Add power glasses

Add power glasses - Glasses designed with additional magnification, primarily used to assist with up-close vision tasks like reading. Commonly found in bifocal and progressive lenses, they help those with presbyopia, a condition where the eyes gradually lose the ability to focus on close objects due to aging. In these cases, the the additional magnification is at the bottom of the lens. There are also single vision add power glasses, more commonly known as reading glasses, where the additional magnification power covers the whole lens.

Eye floaters

Eye floaters - Small, shadowy shapes that appear in your field of vision, often described as spots, threads, or cobwebs. Floaters are usually harmless and result from the breaking down of the vitreous humour, the gel-like substance inside the eye, which occurs naturally with age. However, a sudden increase in floaters, especially when accompanied by light flashes, may signal vitreous detachment and requires prompt medical attention.

Hazel Eyes

Updated On May 05, 2023

Hazel eyes are rare and beautiful, with only 5% of the population having these unique eyes. Read on to find out what causes hazel eyes.

One of the first things you may notice about someone is their eyes. Their colour and expression can be quite prominent, revealing a lot about an individual.

The human eye can reflect someone’s personality and ancestry, show the amount of melanin in the iris and even give a glimpse into one’s current health condition.

Hazel-coloured eyes, while considered rare, are also thought to be one of the most beautiful.

According to researchers at the American Academy of Ophthalmology (2017), around 10,000 years ago, everyone had brown eyes.

Today, approximately 70-80% of the world’s population have brown eyes, making brown the most common eye colour. While not the rarest colour, only 5% of the population have hazel eyes.

How is eye colour determined?

The eye’s iris, the pigmented area surrounding the pupil, gives eyes their colour. Melanin is the pigment responsible for both eye and skin colour.

Hazel eyes are in the brown family, but they feature other colour hues like green and amber in addition to brown.

There is a complex network of genes that determine eye colour in humans. Most of these genes play a role in producing, transporting and storing melanin pigment.

The more melanin you have in your iris, the darker your eyes are. Therefore, people with brown eyes have the most melanin. People with the least melanin have blue, grey, or green eyes. Hazel eyes have more melanin than blue but less than brown.

Babies are not born with the total amount of melanin in their irises. More melanin may accumulate in the iris in the first few years of life, causing a child’s eyes to change or darken.

Blue eyes that change to brown develop significant amounts of melanin, while those that turn green or hazel produce slightly less.

How does light affect different eye colours?

Have you ever noticed that eyes change colour in different environments? This is because of how particular light and sunlight hit and scatter within the iris. Melanin in the iris absorbs different wavelengths of light.

Eyes with a higher concentration of melanin (darker eyes) absorb more light and reflect less from the iris.

The opposite occurs in eyes with lower concentrations of melanin (light-coloured eyes); less light is absorbed, and more is reflected off the iris.

What causes hazel eyes?

Hazel eyes have been called the chameleon of eye colours, changing colour based on their surrounding environment. Are they green, gold, brown or a mix of all?

Hazel eyes are complex, and while what exactly determines hazel eye colour is still up for debate, researchers have narrowed it down to the amount of melanin present, scattering of light and perception.

Hazel eyes have a lower concentration of melanin, causing more light reflection off the iris. This higher level of reflection is why we tend to see changes in hazel, blue, or green eyes.

The distribution of melanin can differ in parts of the iris, causing hazel eyes to appear light brown near the pupil and greener at the edge of the iris.

DID YOU KNOW?

Our eyes can change colour after birth as more melanin is produced, causing lighter eyes to darken.

What's the difference between hazel and green eyes?

The main difference between green eyes and hazel eyes is how melanin spreads in the iris. As mentioned, the melanin in hazel eyes may vary in different parts of the iris, causing different eye colours to appear.

As light is reflected off hazel eyes, it produces other eye colours like green, brown or gold. The melanin in green eyes is more evenly dispersed, causing light to scatter so they appear as one colour: green.

Are hazel eyes rare?

Only about 5% of the world’s population have hazel eyes, making them rare. While anyone can have hazel eyes, they are most commonly found among those of Middle Eastern, Brazilian, Spanish, or North African descent.

The rarest eye colour is green, with only 2% of the population having them. Even rarer than green eyes is heterochromia, a condition where a person has two different coloured eyes. Less than 1% of the world’s population has this condition.

Are people with hazel eyes more at risk for eye problems?

There are some links between eye colour and health factors. People with light-coloured eyes are more prone to ocular melanoma, also known as eye cancer.

This is because those with very light eyes have less melanin, a natural eye protectant.

Wearing sunglasses is a great way to shield your eyes from UV rays. Not only do they help you see clearer when outdoors, they protect against eye cancer and macular degeneration.

Sunglasses are beneficial when spending time outside even on a cloudy day as UV rays are still present.

Changing your eye colour with contacts

For those who are unhappy with their natural eye colour or want to try a different eye colour, coloured contacts may be an option.

Contacts come in various styles, allowing you to experiment with anything from grey eyes to dark brown eyes.

Colour contact lenses require a prescription. If you don’t have one, you can see your eye doctor for an eye exam. An eye doctor can help you choose the best contact lenses for your lifestyle needs.

It is crucial to read the instructions to ensure you have the correct contact lenses and know how to use them.

If worn improperly, they can cause eye irritation, infection, or even sight loss. Always speak with an eye care professional before wearing contacts.

What makes hazel eyes unique?

Hazel-coloured eyes reflect light in a way that makes them change colour. Considered unique because they feature a combination of various colours like brown, green and amber, they are often divided into hazel brown or hazel green eyes.

To enhance your eye colour even further, try wearing different shades that bring out and complement your hazel eyes.

Eye colour is a distinctive and beautiful trait that reflects a lot about someone. It is essential to remember that no matter what your eye colour is, you must take care of your eyes.

Seeing an eye doctor, wearing prescription eyewear if necessary and protecting them from UV rays are a few ways to get started.

Best Glasses for an Active Lifestyle

Eyewear shouldn’t hold you back. Look for durable, lightweight frames with high impact lenses and coatings.

For most of us, living an active lifestyle is something we strive to do. We’ve all understood the importance of movement in our lives.

Whether you’re a seasoned athlete, a weekend warrior, or someone trying to incorporate more physical activity into your life, finding the perfect pair of eyeglasses to suit your active lifestyle is paramount.

In the pursuit of well-being, eyewear should not be a hindrance but a supportive companion.

Good sports eyewear can provide eye protection, enhanced performance, comfort and even support overall eye health.

Whether competing in water sports, trail running, mountain biking, or any outdoor sports, prescription sports glasses or sports sunglasses are an accessory that can improve visual acuity and take your performance from good to great

What is the difference between everyday glasses and sports glasses?

Depending on your level of fitness and training, investing in high-performance eyewear or dedicated sports sunglasses, glasses, or sports goggles is a great option.

Regular eyeglasses and sports glasses serve distinct purposes and are designed with different features to cater to the wearer’s specific needs during various activities.

The first difference you may notice is the overall design and build. Prescription glasses are primarily designed and worn for vision correction.

They are typically made of plastic or metal, and their frames may be more delicate. Sports glasses, on the other hand, are engineered with durability and performance in mind.

They often feature robust, impact-resistant materials and sport-specific designs like rubber grips that prioritise functionality over fashion.

Everyday glasses are fitted with standard prescription lenses optimised for clarity in day-to-day activities. They may not offer features like UV protection, anti-fog coatings, or polarisation.

Sports eyewear can come with specialised lens technologies, such as polarised lenses to reduce glare, anti-fog and anti-scratch coatings for improved visibility and photochromic lenses that adapt in changing light conditions.

Another significant difference is that sports eyewear is designed to stay securely in place during vigorous activities.

Sport-specific frames often have features like rubberised nose pads and temple grips to prevent slipping, ensuring a stable fit.

Standard eyeglasses are not always designed to withstand high-impact activities. They may feature glass lenses which can break or shatter upon impact, posing a risk to the wearer.

Sport-optimised lenses are generally made of impact-resistant materials like polycarbonate or Trivex.

These materials are more durable and can protect the eyes from potential injuries caused by flying objects or collisions.

Wrap around style sports sunglasses are even better at protecting your eyes as they are designed to shield them from wind, dust and debris.

Can I add prescription lenses to my sports glasses?

If you wear prescription glasses and require vision correction, a pair of prescription sport sunglasses or glasses are a great solution to keep you active.

Depending on the specific frame design and offerings, you can often add your prescription to sports glasses.

Keep in mind that not all frames are compatible with prescription lenses, so it is essential to ensure that the frames you choose can be fitted with them before buying.

The first step is getting an updated prescription from your eye doctor. They will assess your vision and determine your prescription needs.

Once you have your prescription, you can select sports glasses compatible with prescription lenses.

From single vision to progressive lenses, many sports eyewear brands offer options for prescription inserts or custom-made lenses that can be fitted into the frame.

At SmartBuyGlasses, you can add your prescription details and customise your lenses for your specific vision needs. There is no need to ditch your prescription glasses to stay active.

It’s important to follow proper care and maintenance guidelines for your sports glasses with prescription lenses, just as you would for regular eyeglasses.

Clean the lenses regularly, avoid harsh cleaning solutions and protect them from scratches.

What are the benefits of wearing sports glasses?

Whether you’re an amateur or professional athlete, wearing sports sunglasses or glasses has many benefits. Some of the biggest benefits include:

They provide eye protection from injuries during sports and other physical activities.
UV protection to help shield your eyes from UVA and UVB rays during outdoor activities.
Prescription sports glasses can help athletes with vision impairments to see clearly.
Sports glasses typically feature polycarbonate lenses, which are more durable than glass lenses.
Certain sport lenses come with anti-glare coatings or polarised lenses.
Sports glasses are made from durable materials and offer a snug fit, so they stay securely in place during physical activity.

Quite versatile, sports sunglasses are available for various sports and activities.

From light walking to cycling and mountain biking, there are specialised designs tailored to the specific demands of each sport, ensuring that athletes have the proper eyewear for their chosen activity.

What to consider when buying glasses for an active lifestyle

If you want to enhance your athletic performance, it’s time to get a pair of sports frames that fit comfortably. Sports sunglasses don’t have to be ugly and bulky.

Finding a versatile pair to take you through the day is easy once you consider a few things. The first step is understanding your face shape.

Some frame sizes and styles may fit certain face shapes better than others. Next, consider your style preferences.

Sports glasses come in various types, from sleek and modern designs to more sport-specific options. Choose a style that suits your taste and the sports or activities you’ll engage in.

The lens colour can significantly impact your performance and visual comfort in different conditions.

Clear lenses: suitable for low-light conditions or indoor sports.
Yellow or orange lenses: enhance contrast and depth perception in overcast or hazy conditions.
Grey lenses: provide accurate colour perception and are excellent in bright sunlight.
Brown or copper lenses: enhance contrast and are ideal for variable lighting conditions.
Mirrored lenses: reflect sunlight, reducing glare in very bright conditions.

Another important thing to consider is the special lens coatings available. Look for sports sunglasses with scratch-resistant coatings.

Scratches on the lenses can impair your vision and compromise safety, especially during intense activities.

An anti-fog coating helps prevent condensation and fogging on the lenses. This feature is crucial for sports that involve rapid temperature changes or high-intensity physical exertion.

Depending on the sport, consider the level of impact resistance your glasses need. For high-impact sports like racquetball or basketball, choose glasses with durable frames and higher impact resistance.

Ensure that the design of the sports glasses does not obstruct your peripheral vision, as this can be crucial for safety in many sports.

Rimless sunglasses are a good option, providing the wearer with an almost entirely unobstructed view.

The best sports sunglasses will vary depending on the wearer. Be sure to weigh up your options and tailor your choice to your specific sport and personal preferences.

Then, you can select the right pair of sports glasses that enhance your performance and protect your eyes effectively.

DID YOU KNOW?

Various organisations, such as the American National Standards Institute (ANSI) and the European Committee for Standardization (CE), have established standards for sports eyewear to ensure they meet specific safety and performance criteria.

Tips for working out in glasses

Working out with glasses can be tricky. You’re moving a lot, and sweat may cause your frames to slide down your face. The last thing you want is for your glasses to slip off while exercising.

Don’t let your glasses keep you from working up a sweat! Opt for lightweight and durable materials like titanium or plastic when choosing frames.

A snug fit on your face and rubberised nose pads or temple tips can help your glasses stay put and prevent slipping during workouts.

Many sports glasses come with adjustable straps that can be secured around your head to keep them in place during intense activities. This helps prevent them from falling off or sliding down your nose.

If you tend to sweat during workouts, use a sweatband or headband to help absorb moisture and prevent it from dripping onto your lenses. This can help keep your glasses clean and fog-free.

Regularly clean your glasses with a microfiber cloth to remove sweat, dirt and smudges. Dirty lenses can affect your vision and become a distraction during exercise.

Lastly, be sure to schedule regular eye exams to ensure your prescription is up to date and that your eye health is in good condition. This will help ensure you have the right glasses for your workouts.

How to find the best glasses for an active lifestyle

As discussed, finding the best glasses for active lifestyle involves considering various factors to ensure that your eyewear is comfortable, durable and suitable for your specific activities.

Be sure to fit your frames with lens tints and coatings that match your active lifestyle. Polarised sunglasses are a great option if you engage in watersports or driving, as they reduce glare.

Some sports glasses offer interchangeable lenses, allowing you to switch between clear, tinted, or polarised lenses based on lighting conditions.

Photochromic lenses, which automatically darken when you transition from indoors to outdoors, are another excellent lens option.

Remember that the best glasses for an active lifestyle will be tailored to your needs and preferences.

Take your time to make an informed decision and consult with an optometrist or one of our certified opticians for personalised recommendations if needed.

Don’t let your eyewear keep you on the sidelines. It’s time to embrace your sporty style and take your performance to the next level with versatile sunglasses or glasses designed for an active lifestyle.

Strabismus: Explanation and Treatment Options

Strabismus: Explanation and Treatment Options

What is strabismus? Learn about its causes, symptoms (including when they appear) and treatments.

Have you ever wondered if there are glasses able to correct strabismus? Or if any other treatments can help? Find all the information you need about strabismus, what it is, why it occurs, and all the treatment options.

What is strabismus?

Strabismus (also sometimes known as crossed eyes) is a condition where one of the eyes is not aligned with the other – i.e.; it looks in a different direction from the other eye.

Six muscles control the movement of the eyes. Under normal conditions, these muscles work together and point the eyes in the same direction. When strabismus occurs, one of the eyes works differently and has a problem keeping ocular alignment.

Proper eye alignment is needed to avoid seeing double, for good depth perception, and to prevent poor vision in the turned eye. When the eyes are misaligned, the brain receives two different images. This may create double vision and confusion. However, over time, the brain will start to ignore the image received from the turned eye.

Strabismus can be constant or intermittent, which means it can either be constantly present or only be present at times. Other two types include:

Unilateral strabismus occurs when the misalignment affects the same eye.
Alternating strabismus happens when your eyes may take turns being misaligned.

Based on the direction of the misaligned eye, there are four types of strabismus:

Esotropia: inward turning
Exotropia: outward turning
Hypertropia: upward turning
Hypotropia: downward turning

DID YOU KNOW

Strabismus usually appears during the first three years of age, but cases of adult strabismus are also very common.

Strabismus symptoms

Based on what age the strabismus occurs, different symptoms may appear. In adults, signs of strabismus might include:

Weakness in the eye
Vision changes (double vision, blurry vision, loss of depth perception)
Constant tilting of the head to see an image clearly

Strabismus is one of the most common eye conditions in children. Children can either be born with strabismus or acquire it later. Strabismus should be diagnosed as early as possible to prevent vision loss and be able to take the necessary precautions. Signs of strabismus (crossed eyes) in children can include:

The eyes are always turned outward or inward during the first three months of age
After the first three months of age, one or both eyes are crossing in
Red-eye infection in one eye

If not diagnosed and treated early, strabismus can result in amblyopia, also called ‘lazy eye.’ Amblyopia causes vision to not develop properly in the misaligned eye and can eventually lead to complete vision loss. Another complication is double vision, not to mention the personal side effects of having a misaligned eye.

When do the symptoms of strabismus appear?

By the age of three to four months, the infant’s eyes should be able to focus on small items and remain straight. The baby should easily focus on objects both near and far away. Strabismus is common among infants and usually appears by the time the child is three years old.

False strabismus can make it seem like the child has a misaligned eye when the eyes are aimed in the same direction. With the baby’s growth and development, the eyes will no longer appear crossed.

What causes strabismus?

As previously explained, strabismus occurs when the six muscles that control our eye movements don’t work correctly. 30% of the children with strabismus have inherited the condition from their family history and have a family member with a similar problem.

Down syndrome (20-60% of patients with Down syndrome are affected)
Stroke (is the leading cause of strabismus in adults)
Head injuries (if the damaged area of the brain is responsible for the control of eye movement)
Brain tumors
Poor vision in one eye

The eyes are always turned outward or inward during the first three months of age
After the first three months of age, one or both eyes are crossing in
Red-eye infection in one eye

How is strabismus diagnosed?

Strabismus is diagnosed after a complete eye examination with an ophthalmologist or optometrist. The exam can include different things, such as:

The examination of patient history to determine if any other complications may cause strabismus and affect it.
Examination of eye health to determine the overall health of the eye; based on when the patient has been diagnosed, there might already be some damage to the eye.
Visual acuity test to measure the visual acuity and determine how much vision is being affected in the misaligned eye.
Alignment and focusing tests assess how well the eyes align and move together.

Once all tests are done and completed, based on the diagnosis, your eyecare specialist can discuss with you and suggest treatment options.

Can strabismus be prevented?

Unfortunately, strabismus cannot be prevented; however, if detected early and properly treated, it can be corrected. When it comes to strabismus treatments, there are several options:

Eyeglasses or contacts
Patching: covering the misaligned eye with a patch every day for a few hours can help remind the brain which ‘correct eye’ needs attention. This can sometimes lead to a better alignment of the misaligned eye.
Prism lenses: these lenses are thicker than usual lenses and can alter the light that reaches the eye; this results in the eye having to move less to see properly. In some cases, prism lenses can eliminate eye turning.
Visual therapy: your eyecare specialist might prescribe a few visual activities to improve eye coordination and eye focusing. These eye muscle exercises can be done with a professional’s help or at home.
Eye muscle surgery: this intervention changes the length and position of the muscles around the eye so they don’t look misaligned anymore. After this type of surgery, visual therapy is often advised.
Medications

Based on the severity of the strabismus, some treatments might be more effective than others. Cases of mild strabismus may only require glasses or patching, while severe cases might require eye muscle surgery.

Can strabismus be fixed?

Adult strabismus can be treated in various ways; just like for children, not treating strabismus can be extremely dangerous for the eye’s overall health.

Studies show that improvement is possible at any age when it comes to strabismus. The recovery speed might differ, but adults can still achieve great results by doing visual therapy, wearing glasses, and taking all the necessary measurements to improve.

Adult strabismus surgery is also very common, mainly because it is easier for adults to undergo surgery than for children.

False strabismus can make it seem like the child has a misaligned eye when the eyes are aimed in the same direction. With the baby’s growth and development, the eyes will no longer appear crossed.

Glasses for strabismus

When it comes to glasses, it is important to note that there are no special glasses that correct strabismus.

After consulting with an ophthalmologist, the treatment of strabismus can include wearing corrective lenses. In some cases of mild strabismus, prescription glasses can even correct the alignment. Based on the condition of the eye, the doctor can either suggest prism lenses or not.

Do glasses help with strabismus?

Again, depending on how severe the strabismus is, eyeglasses might be able to correct the alignment and are mainly used in patients with uncorrected refractive errors.

Although it is impossible to prevent, strabismus can be treated. With the help of an ophthalmologist and if diagnosed in time, being proactive about treatment can prevent vision loss and even correct the misaligned eye.

New Glasses Problems: How to Avoid Marks on Your Nose

They may seem unavoidable, but there are measures you can take to prevent your glasses from leaving marks on your nose.

The benefits of wearing glasses – namely, being able to see and interact with the world around you – far outweigh the downsides, but there are still a couple of small inconveniences that can come with the territory.

One of these is the indentations or red marks they can leave on your nose. These unsightly impressions can be a source of discomfort and annoyance, especially after a long day of wearing your favorite frames.

If you’re tired of those tell-tale red patches that broadcast to the world that you wear glasses, this article will guide you on how to enjoy the functionality of your specs, without having to put up with the notorious nose marks.

Thanks to these practical and effective solutions, you’ll never have to Google “mark on nose from glasses” again!

Why do I have marks on my nose from my glasses?

Some people have no issues with nose marks from their glasses, while for others, they’re a daily occurrence. If your glasses leave marks on your nose bridge, there are a few possible explanations, many of which are linked to how they fit you.

Weight distribution and pressure

The primary reason glasses leave marks on the nose is due to the combined weight of the frames and lenses. The nose pads are the primary point of contact between your skin and your glasses.

All of the pressure created by the weight of the glasses is exerted through the relatively small surface area of the nose pads and the small area of skin they rest on.

The heavier your frames and lenses, the greater chance of nose marks. If the weight of your glasses is unevenly distributed, the glasses marks may be intensified on one side of your nose bridge.

Skin sensitivity

The skin on our noses is delicate, making it more prone to indentations. Prolonged pressure from the nose pads of glasses can cause the skin to compress, leading to temporary marks. For some individuals with especially sensitive skin, this can even lead to irritation or redness.

Sweat and friction

Sweat can exacerbate the situation. When our noses sweat, it can reduce the friction between the skin and the nose pads. This leads to the glasses sliding down the nose, and the wearer pushing them back up, creating more pressure and friction, which further contributes to those pesky marks.

Material and type of nose pads

The material of the nose pads can also play a significant role. Some materials may be harder or less forgiving than others, leading to more pronounced indentations. Soft nose pads made from silicone, for instance, may be gentler on the skin than harder plastic varieties.

Short-term solutions

If you’re looking for a quick fix to make the marks on your nose disappear, there are a few things you can do to ease the redness and irritation in the short term.

Massage your nose

Regularly massaging the bridge of your nose can help improve blood circulation, which, in turn, can speed up the healing process and reduce the appearance of red marks.

Using your fingertips, gently rub the affected areas in circular motions for a few minutes daily. This not only stimulates the blood flow but also soothes the compressed skin.

You can enhance this massage by applying a moisturiser or a gentle natural treatment like aloe vera gel, both known for their soothing properties.

Wash your face regularly

A clean face not only feels refreshing but can also prevent and soothe red marks. Using a gentle facial cleanser, wash your face at least twice a day, especially after any sweaty activities.

This helps to remove any build-up of oils, sweat and dirt that might exacerbate skin irritation.

After washing, pat your face dry with a soft towel and apply a light moisturiser. This will keep your skin hydrated, aiding in the faster healing of those marks.

Take a break from your glasses

Giving your skin some breathing room can make a world of difference. If possible, consider switching to contact lenses for a portion of the day. This provides your nose with a much-needed break from the constant pressure of glasses and their nose pads.

If contacts aren’t an option, try taking off your glasses for short intervals when you don’t need them, such as when reading up close or before bedtime.

Remember, even a brief break can significantly reduce the prolonged pressure that contributes to red marks.

DID YOU KNOW?

Lightweight plastic frames with a fixed pad bridge are the best option for avoiding red marks.

Long-term fixes

The steps outlined above can provide some relief, but they don’t exactly address the root of the problem. If red marks on your nose bridge are the bane of your life, you’ll want to try some of these solutions.

Choose lightweight glasses

The weight of your glasses plays a significant role in the intensity of the red marks. The heavier the frames and lenses, the more pressure they exert on your nose.

Opt for frames made of lightweight materials such as titanium or thin plastic, as opposed to heavier metals or bulky constructions.

Similarly, if you have a strong prescription, consider high-index lenses, which are thinner and lighter than standard lenses. The reduction in weight minimises the pressure and the resulting marks.

Choosing glasses that have an enlarged flat surface on the inner section of the rim – known as a fixed pad bridge – instead of nose pads can also be a solution to the problem.

These types of glasses rest directly on the nose bridge and often distribute the weight better than those with small nose pads, reducing the likelihood of red marks.

Loosen the temples

The temples of your glasses, if too tight, can exert excessive pressure on the sides of your nose, causing discomfort and leaving marks. If your glasses constantly feel tight, it might be time for a simple adjustment.

Loosening the temples slightly can make a huge difference. Visit an optician, as they will know exactly what they’re doing, and many offer free adjustments.

Remember, glasses should fit snugly but not tightly. They should sit comfortably on your nose without pressing into your skin.

Adjust the nose pads

The nose pads of many glasses are flexible, and can be adjusted by hand, without using any tools. Try varying the positioning and angle of the nose pads for greater comfort.

If they aren’t flexible, don’t force them. Instead, bring your frames to an optician and ask them to adjust the nose pads for you.

There’s always a solution

Red marks from glasses on your nose don’t have to be a daily annoyance. Try out some of the tips we’ve suggested here to deal with them, and the next time you buy a new pair of glasses, keep those points about lightweight styles and adjustable nose pads in mind.

Technology in the eye industry is constantly evolving. Today, it is easier and more efficient than ever to get a copy of your eye prescription. Gone are the days of waiting in long lines to receive your prescription from the optician’s office.

Read on to learn more about eye prescriptions, where to get them, and how to read them.

Where can I get a copy of my eye prescription?

Your eye prescription (also known as Rx prescription) is written by an eyewear prescriber, such as an optician or optometrist. It specifies the value of parameters needed to construct and dispense corrective lenses for a patient.

It is recommended that you get an eye test from your doctor at least every two years to check the health of your eyes and if your eyesight has changed. Before buying a new pair of glasses, it is vital that your prescription is up to date.

If you have not had an eye test in recent years, consider booking an eye test with an optician before trying to obtain your current prescription.

How long does it take to get prescription glasses?

Standard in-person eye tests usually take around 30 minutes. Once your eye test is complete, your doctor will provide you with your prescription card.

If you ever misplace your card, you can call up your doctor and request a copy of your prescription.

However, there is an even quicker way to find out your eye prescription. If you simply need a retrieval of your current eye prescription from your current glasses, you can use our revolutionary technology to reveal it without leaving the house.

At SmartBuyGlasses, you can extract your current prescription in a matter of minutes from your glasses with the innovative vision testing Lens Scanner App.

By scanning your current prescription glasses, you’ll have access to your current prescription in minutes, completely free of charge.

This is perfect for individuals who are happy with their current prescription but would like to update their eyewear.

Can I get a copy of my eye prescription online?

Depending on the practice you attend, some opticians may be able to provide you with your eye prescription online. Following your eye test, your prescription will be registered at the optical practice where you had the eye exam.

It is a legal requirement to provide you with your prescription for glasses or contact lenses upon request.

Both opticians and the customer benefit from being able to access prescriptions online due to convenience and time. Usually, you can visit your practice’s website to request the prescription, call them, or send an email.

Some companies may even be able to send over prescriptions on the same day. Simply search the practice and location online to find out more about the best way to contact your optician.

DID YOU KNOW?

Getting your prescription can be quick and easy! If you are in a pinch and have your correct prescription glasses at hand, you can use our handy LensScanner tool to get your prescription details.

How accurate are online prescription glasses?

There will be no changes made to the prescription you obtained from your optometrist, even if they publish it online, so it is 100% accurate.

As for our Lens Scanner App, when used correctly, it can accurately reveal the power in your lenses in a matter of moments.

Please be aware that using the Lens Scanner App cannot be used for progressive lenses and is not a substitution for an eye exam.

We recommend getting an eye exam if you have noticed changes in your eyesight and to check your eye health.

Can I see my prescription history?

It may be beneficial for you to look into your eye prescription history to see the changes in your eyesight over the years. You can request your eye prescription history from your optician via phone call, email, or by visiting the branch.

Some opticians allow you to access your prescription history online via their website, so it’s worth checking this out first.

Please note that requesting your prescription history can take longer than requesting your current prescription, as there are more details to prepare.

Generally, a prescription will include the following information: sphere power, cylinder power, axis, and ADD power.
Sphere power indicates how strong your prescription lenses should be to correct any near or Farsightedness. This number can range from negative numbers (for Nearsightedness) to positive numbers (for Farsightedness). The greater the number, the stronger the prescription needed to correct vision problems.
Cylinder power indicates if astigmatism is present and the amount of correction required by referencing a minus or plus sign and a numerical value. If this field is left blank on your prescription, it means no astigmatism is present.
Axis indicates the angle of your prescription lenses, expressed in degrees on a scale from 0-180. This number will usually have a small “x” placed before it to indicate that it is an axis measurement.
Finally, ADD power indicates how much prescription strength you need for reading and other tasks requiring near vision. This field is typically filled out if you are over the age of 40, as people typically start to need prescription lenses for seeing up close around this age.

By understanding these key elements of an eye prescription, you can discover more about your own optical health and decide which glasses are perfect for you.

High Index Lenses

Thick lenses are an aesthetic concern for many people, but high index lenses allow strong prescription lenses to be thinned. Learn all about them in this article.

Lens index indicates how thick or thin a lens is. Also known as the index of refraction or refractive index, it is measured by numbers and describes how efficiently a material bends light. High-index lenses allow people with strong prescriptions to wear eyeglasses with thinner lenses.

Read on to learn what high-index lenses exactly are and how they compare to other types of lenses.

What are high-index lenses?

High-index lenses are thin, light, and powerful lenses. Prescription glasses equipped with high-index lenses are noticeably slimmer, more lightweight, and more stylish. That’s why high-index lenses are recommended for people with strong eyeglasses prescriptions.

Typically, those with higher vision correction needs will be forced to wear thicker and bulky conventional glass or plastic lenses that are thicker towards the edges. But with the emergence of high-index materials, the optical industry has been transformed.

Now, strong refractive errors such as myopia, hyperopia, presbyopia, and astigmatism can be corrected with thinner lenses with no compromise on efficacy.

Thanks to high-index lenses, strong prescription glasses can now be sported in stylish, semi-rimless, and even rimless styles. Most high-index lenses are also aspheric, making them slimmer and eliminating the “bug-eye” look to a great extent.

What are high-index lenses made of?

Most high-index lenses are made of a particular type of light plastic that bends light more efficiently than other lens materials. There are also high-index lenses made of glass, but they are recommended or prescribed less often.

DID YOU KNOW?

The first high index lenses were produced in 1983, made from polycarbonate.

High-index lenses vs. regular

Both regular lenses and high-index ones bend light to correct refractive errors. The difference is that regular lenses have to be thicker to correct strong prescriptions, while high-index lenses are made of a material that makes them lighter and thinner.

In general, the stronger the prescription, the higher the index should be for the glasses to offer comfortable vision and fit. For example, a regular lens with a 1.50 index and a 1.67 high index lens can have the same prescription, but the high index lens would be around 30% thinner.

High-index lenses vs. polycarbonate

Polycarbonate lenses have a 1.59 index, making them thinner than standard lenses but not as much as high-index lenses.

They are also impact-resistant, offering increased durability. In general, polycarbonate lenses are only recommended for children’s glasses, sports eyewear, and safety goggles because they don’t provide the same visual clarity as other plastic lenses.

1.67 vs. 1.74 high-index lenses

Both 1.67 and 1.74 high-index lenses can accommodate strong prescriptions. The difference is in the thickness. 1.74 high-index lenses are up to 10% thinner than 1.67 high-index lenses.

As a reference, 1.67 high-index lenses are recommended for strong prescription with an SPH correction between +/-7.00 and +/-9.00, and a CYL correction between +/-3.25 and +/-4.00.

1.74 high index lenses are known “as thin as possible” lenses and are recommended for even stronger prescriptions with SPH corrections around +/-9.25 and above, and CYL corrections around +/-4.25 and +/-6.00.

They are 35% thinner than the standard lenses. Although they appear thin, they are at the same time strong and will include the features to correct vision problems.

Are high-index lenses worth it?

High-index lenses are the solution for accommodating high prescriptions in thinner lenses. That is not all, though; here are all the advantages of choosing high-index lenses:

Thinner and lighter than other lenses: the specific plastic blend makes it possible to create thinner and lighter lenses that provide better light refraction than regular ones.
Versatility: high index lenses can be customized according to your needs and preferences. They can be single vision, progressives, transitions, and can be treated with many coatings such as blue light, polarization, anti-reflective, and more.
Comfort: because they are lighter and thinner than other types, high-index lenses offer a higher level of comfort. With high-index lenses, your glasses will not be heavy on your ears and nose, making your life easier.
Great fit for most frames:high index lenses fit thousand of different frames. Always remember that the bigger the frame, the thicker the lens, so opticians recommend smaller frames if you have a strong prescription.

Disadvantages of high-index lenses

More fragile than other lenses: high index lenses are not as impact resistant as other types of lenses. This means that they are not indicated for children or sports.
More expensive than other lenses: These lenses offer many benefits but are also a bit more expensive than regular lenses. For many wearers, though, their benefits outweigh the price difference compared to lower index lenses.

High-index lenses might be perfect if you want more comfort and a better appearance. Before deciding on your lens index, talk to your eye doctor or take advantage of our free online optician support service to see which lens is best for your eye prescription.

Buying glasses online shouldn’t be daunting, in just a few easy steps you can find the perfect pair that suit you and your vision needs.

We buy many things online, from groceries to clothes, and while these things seem “normal,” some products are considered a bit more complex. Purchasing eyewear online may seem exciting, but with questions like frame fit and prescription accuracy, it can be daunting to some.

At SmartBuyGlasses we guarantee that with a few easy steps and access to our online opticians, buying prescription glasses online is simple and easy. Our customer service team is also available to help you along the way.

What do I need to buy glasses online?

When purchasing prescription eyeglasses from online glasses retailers, you will usually need three things:

Your up-to-date eye prescription
Your pupillary distance
Your vision insurance information (if you have coverage)

An updated eye prescription is necessary for purchasing prescription glasses. It’s important to always schedule your yearly eye exam with your eye doctor to identify vision problems, write your prescription, and address your eye care needs.

You don’t need a prescription if you’re purchasing blue light glasses, sunglasses, or other non-prescription eyewear. However, even if you don’t require prescription eyewear, having an eye exam at least every two years is still important to maintain eye health.

Can I order glasses online without a prescription?

If you require prescription lenses, you will need an up-to-date eye prescription during the ordering process. Your glasses prescription is essential to ensure you get the proper vision correction. If you’ve misplaced your prescription, you can use our Lens Scanner app to retrieve your prescription information from your current pair of single vision lenses.

Advantages of buying glasses online

There are many advantages to buying glasses online, convenience being one of the biggest. From the comfort of your home, you can shop for new eyewear on your own time. Shopping at your leisure removes the pressure many people face in-store.

Shopping online for glasses also gives you access to a more extensive selection of frames, making it easier to find a new pair. Online you can browse various brands, styles, and colours. Prices online tend to be more affordable, and with the opportunity to compare prices, you are guaranteed to find the perfect pair at the best price.

Ordering prescription glasses online

Buying a pair of glasses shouldn’t cause any stress or for you to pay too much money. If it’s your first time purchasing eyeglasses online, follow these simple steps.

1. See an eye doctor to get an updated prescription

As mentioned, seeing an Optometrist for an eye exam and receiving an updated prescription is the first step in buying glasses online and ensuring clear vision. At SmartBuyGlasses, you have the option to upload, manually enter, or send in your prescription after the check-out process.

2. Choose your frame width

Purchasing glasses that fit properly is essential. Glasses should fit your face correctly in order to provide the best correction. Our ‘medium’ frame width works well for most people, but we carry glasses with frame measurements from 38mm-69mm. We also offer a low bridge fit, ideal for those with higher cheekbones and a flatter nose bridge.

Your pupillary distance (PD) and frame measurement from your current glasses can help determine the best size for you. PD reveals how far your pupils are from one another and is helpful in centring your frames on your face.

Check the inside arm of your current glasses frame for the lens width, nose bridge size, and temple arm length. Whether you’re happy with the fit of your existing frames or want to change something, these numbers can aid you in the selection process.

DID YOU KNOW

Buying glasses online is not only easy and convenient but can also be fun. With virtual try-on technology, you can now see how glasses will look on you before purchasing.

How can I get my pupillary distance?

Your PD will usually be measured as part of an eye exam and then written on your prescription. If you misplace your prescription, there are two simple ways to get your PD; use our Pupillary Distance app to retrieve the details or measure it yourself.

The Pupillary Distance app enables you to get your PD quickly and easily with only your phone or computer, and a card with a magnetic strip. If you don’t have access to the tools required to use our app, you can easily measure your PD yourself. All you need is a ruler and a mirror. To measure your PD at home:

Stand in front of a mirror and hold a ruler to the bridge of your nose or against the line of your eyebrows.
Close your right eye and align the ruler’s zero with your left pupil.
Keep the ruler still, then close your left eye and open your right eye.
The number aligned with your right pupil’s center is your PD measurement.

3. Find frames that suit your face shape

While you can wear any glasses frames you want, certain frame styles suit particular face shapes. If you’re unsure of your face shape, follow these easy steps.

Look in the mirror and outline your reflection on the mirror with a bar of soap or lipstick.
Consider the shape you’ve just drawn; compare and match it to a standard face shape below.

After you’ve understood your face shape, it’s time to choose a complimenting frame.

How do I know what style of glasses to get?

If you have an oval face, you can wear almost any style, including oversized glasses, rectangular, square, round, or cat-eyed frames. For those with a square face, you should opt for oval or round glasses to soften your features. You can use rectangular, square, or cat-eye glasses to add sharp angles and definition if you have a round face shape.

People with heart-shaped faces tend to have wider foreheads and a narrow chin. This shape works well with various styles, including rectangle, oval, and cat-eye. The least common face shape is diamond; a geometric, rectangular, or oval frame would work well for this shape.

4. Find a frame that suits your style

Of course, it’s important to understand what frames may look best on you, but it’s also important to consider your style and what may make you feel the best. Everyone has a certain sense of style, whether subtle or bold, neutral or bright, or anything in between; finding eyewear to match your aesthetic is essential.

Consider the type of glasses frames you want. Do you prefer rimless or full-rim frames? Be sure to consider the frame material as well. Metal or titanium frames are minimalistic and sleek. Plastic frames are generally lightweight and comfortable for everyday wear.

Don’t forget about colour. These days, frames are available in all colour blocks, gradients, and patterns. Think about how and where you’ll wear your glasses or sunglasses, then select the frames that best fit your lifestyle and complete your wardrobe.

5. Choose your lenses and coatings

Now that you’ve chosen frames, it’s time to select your lenses. With a wide range of lenses available, it may be hard to know which to select. Most frames can be fitted with prescription lenses, including single vision and progressive, and coatings like blue light block. Every lens has its benefits, so it’s essential to understand what you need from your new eyeglasses.

Your prescription for eyeglasses will guide you in choosing your lenses for vision correction. If you want to reduce eye strain caused by too much screen time, an anti-glare coating can be added to your lenses.

SmartBuyGlasses has many different lens options and will recommend lenses based on the frames you choose to ensure they’re not too thick or thin. Lenses are available at different widths, with anti-reflective coatings, UV protection, and other features. To learn more about different lenses, head to our Lens Hub to read more.

6. Place your order

Now that you’ve found your perfect frames and added lenses, it’s time to place your order. Before purchasing, check with your insurance provider to see if they will cover all or some of your frame or lens costs.

At check out, enter your payment details, and if you have vision insurance, be sure to download an invoice and claim a reimbursement directly with your provider. It’s important to note that SmartBuyGlasses offers 100-day returns and a 2-year warranty so you can feel confident when you shop online.

Can I try on glasses when ordering online?

With advances in virtual AI technology, you can now try on over 10,000 glasses before purchasing your new pair using our Virtual Try-On tool. With so many frame styles, a virtual try-on is helpful as you begin your search.

To get started, all you need is your phone or computer. You’ll take a short video of yourself and then are free to try on frame after frame for as long as you want, eliminating any pressure or embarrassment you may experience in a retail store.

Is it a good idea to buy glasses online?

Buying glasses online has many benefits. Finding quality glasses online doesn’t have to be complicated or costly. Besides taking advantage of online savings, you can avoid shopping in-store, where you may only be able to try on up to five frames.

Shopping online for eyewear opens the door to an endless amount of frames and lenses. It allows you to experiment and find a frame style that may not be available in-store.

Hopefully, how to buy glasses online is a bit clearer, and you’re ready to try it. SmartBuyGlasses carries one of the largest eyewear selections for men, women, and kids.
