What Exactly is an Eye Chart?

If there’s one aspect of optometry that everyone recognizes, it’s the traditional eye chart, with its rows of big letters on top, which gradually become smaller the farther down you go. This chart is usually known as the Snellen chart.

Yet how much do you really know about this eye chart? Are all eye charts the same? How are these eye charts used? And when were they invented?

Here’s everything you need to know about eye charts and more!

What is an Eye Chart?

An eye chart is one of the tools your eye doctor uses to assess your eyesight. Based on how well you can see various letters on the chart, your optometrist will determine whether you have myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age-related farsightedness) or astigmatism, and will measure the prescription that will give you the clearest, most comfortable vision.

Are All Eye Charts The Same?

There are a number of variations to the standard Snellen eye chart. The one an eye doctor uses depends on the personal needs and abilities of the patient. For example, eye doctors will use charts with pictures or patterns for younger children who may not have learned to read or identify letters and numbers.

There are also certain charts that specifically measure distance vision, while others are better for measuring near vision.

History of the Snellen Eye Chart

The Snellen eye chart was developed by Dutch eye doctor Hermann Snellen in the 1860s. Before this standardized eye chart was developed, each eye doctor had their own chart that they preferred to use.

Having so many different eye charts made it impossible to standardize the vision correction available to patients. Eyeglass makers didn’t receive the defined measurements they needed to accurately design, manufacture and measure the optical prescriptions their patients needed.

For the first time, the Snellen eye chart allowed a person to provide a standardized prescription from any eye care provider they chose to any eyeglass maker, and get the same optical lenses to accurately correct their vision.

How The Snellen Chart Is Used in Eye Exams

The standard Snellen chart displays 11 rows of capital letters, with the first row consisting of a single large letter. The farther down the chart you go, the smaller the letters become.

Your Markham eye doctor will ask you to look through a phoropter – an instrument used to test individual lenses on each eye during an eye exam – and look at the Snellen chart placed 20 feet away. Your eye doctor will prescribe the lenses that provide you with the clearest and most comfortable vision.

In many offices, where 20 feet of space may not be available, you’ll be asked to view the chart through a mirror. This provides the same visual experience as if you were standing 20 feet away.

If you have 20/20 vision, it means you can see what an average person can see on an eye chart from a distance of 20 feet. On the other hand, if you have 20/40 vision, it means you can only see clearly from 20 feet away what a person with perfect vision can see clearly from 40 feet away.

If you have 20/200 vision, the legal definition of blindness, this means what a person with perfect vision can see from 200 feet away, you can see from 20 feet away.

Does 20/20 Visual Acuity Mean Perfect Vision?

No. While eye chart tests identify refractive errors, they can’t detect signs of visual skill deficiencies or diseases such as glaucoma, cataracts or macular degeneration. These are diagnosed using advanced equipment as part of a comprehensive eye exam with your local Markham eye doctor. Early diagnosis and treatment of eye conditions are essential to ensuring long-term vision and eye health.

Q&A With Your Local Optometrist

How do you keep your eyes healthy?

You only have one set of eyes – don’t take them for granted!

Make sure to implement the following habits for healthy eyes (and body). These include:

  • Eating a balanced diet rich in fiber, fruits and vegetables
  • Drinking plenty of water to hydrate your body and eyes
  • Not smoking, and avoiding 2nd-hand smoke
  • Wearing sunglasses to protect your eyes from ultraviolet (UV) rays
  • Maintaining normal BMI with regular exercise
  • Regular visits to your eye doctor as recommended

What health conditions can an eye exam detect?

A comprehensive eye exam can often detect certain underlying diseases that can threaten your sight and eye health, such as diabetes, high blood pressure, high cholesterol, tumors, autoimmune conditions and thyroid disorders. This is why having your eyes checked regularly is key. The earlier the diagnosis and treatment, the better the outcome and the higher your quality of life.

Markham Optometrist – 5 Foods Can Help Improve Eye Health

Beyond your annual eye exam, there’s one big thing you can do for yourself to prevent eye disease and keep your vision clear and your eyes healthy. Eat right!

Keywords:

5 Popular Foods For Great Vision and Healthy Eyes

At Dr. Laura Di Nino, our eye doctors care about your overall vision and eye health. During an eye exam, we’ll check for the presence of eye conditions and diseases such as macular degeneration, cataracts, diabetic retinopathy and glaucoma. We’ll also check if you need glasses or contacts for refractive errors such as myopia, hyperopia or astigmatism.

But what foods help the most for keeping your eyes healthy? Here’s a list of 5 popular foods for optimum vision and eye health:

Spinach

Spinach is a great example of a dark leafy green that is high in folic acid. This helps preserve the health of the optic nerve (the part at the back of the eye that sends visual information to the brain) and prevent degeneration. It is also high in lutein and zeaxanthin, antioxidants that can’t be naturally produced by the body, and which act as a sort of “sunglasses” for the macula, helping protect it from the harmful effects of blue light and UV radiation. High concentrations of these antioxidants reduce your risk of macular degeneration.

Sweet Potato

For a great source of vitamin A and beta-carotene, sweet potatoes are a great choice. Eating a baked sweet potato or a slice or two of sweet potato pie can help maintain eye health by reducing your risk of developing eye infections. Eye care professionals also suggest that vitamin A may also help reduce or prevent dry eye symptoms and improve night vision.

Carrots

If there is one superfood that our eye doctors would recommend for a huge boost to your eye health, it would be carrots. A single carrot provides a whopping 200% of the recommended minimum daily amount of vitamin A. Throw in critical minerals such as vitamins B, K, and C, as well as fiber and magnesium, and carrots simply can’t be beat as a must-have in your eye health diet.

Orange

Sweet potatoes, carrots… If we’re talking about orange foods, you can’t forget the delicious tang of oranges! These tasty citrus fruits are heavyweights when it comes to vitamin C, promoting overall body health and reducing inflammation in the eyes that can lead to dry eyes and infection.

Vitamin C also helps promote blood vessel health. This prevents weak blood vessels from leaking into the retina, causing diabetic retinopathy and retinal detachment.

Amla

Not everyone has heard of this native Indian fruit, which is rich in vitamins A and C, as well as carotene. These are all essential for preserving the healthy structure and function of the eye and preventing various eye disorders and diseases. Eating only one of these delicious fruits each day can reduce cataract problems and intraocular tension, as well as combat itchy, red, watery eyes.

Eating right is a great way to minimize your risk of developing potentially sight-threatening eye diseases and conditions. To find out more about what foods can help keep your vision clear and your eyes healthy, speak to our optometrists at Dr. Laura Di Nino in Markham today.

Markham Optometrist – 3 Signs It’s Time To Get New Glasses

Did you know that people spend an average of seven hours every day staring at screens? What’s more, studies have shown that a whopping 68% of people regularly use more than one digital screen at the same time. This could mean using a smartphone while watching TV, a laptop while on a tablet, or any other combination of similar digital devices.

Keywords:

How Do I Know If I Need New Glasses?

If you’re constantly tethered to your electronic devices, it’s important to learn to recognize when you need a change for better, more comfortable vision.

Don’t let your vision suffer because of too much screen time! Visit your Markham eye doctors at Dr. Laura Di Nino and make sure you have the perfect pair of new glasses to give you crisp, comfortable vision all day long.

3 Signs You Need New Glasses:

Changes in your vision:

If you experience vision problems like blurry or double vision or if you have to squint in order to read or see objects clearly, it may be time to visit us for a comprehensive eye exam. New glasses with an updated lens prescription may be just what you need to get your vision back on track.

Eye strain and fatigue when doing computer or other close work:

If you work on your computer or other digital screens for significant parts of your day, you may experience symptoms such as neck pain, headaches, and dry eyes. These can signal a condition known as digital eye strain. Along with a new prescription, you may also consider speaking to our eye doctors about special anti-glare and anti-blue-light coatings for your lenses, to provide an additional layer of protection.

Lots of time in the sun:

Long periods of time in the sun either as leisure or as part of a job that requires a lot of time outside, can cause your eyes to become irritated. Prescription sunglasses with a gray tint and a high rating for UV protection can help keep vision clear and comfortable while you’re out and about.

Bloodshot Eyes – Should You Be Concerned?

You wake up in the morning ready to start your day, only to discover that your eyes are bloodshot. That might not be surprising if you stayed up late to finish a project, had too many drinks at a party or spent time in a smoke-filled room.

But bloodshot eyes can also signal an underlying eye problem. If your eyes appear red or bloodshot, make an appointment with an eye doctor for a comprehensive eye exam to determine the cause and to receive effective treatment.

Why Do I Have Bloodshot Eyes?

When blood rushes to the front of the eye, the tiny red blood vessels on the white of the eye dilate and become visible. This makes the eyes appear red and irritated.

So why do these blood vessels dilate, causing your eyes to look bloodshot?

Bloodshot eyes tend to be caused by:

  • Dry eyes
  • Irritants such as smoke, pollen and perfume
  • Lack of sleep
  • Excessive alcohol consumption
  • Spending too much time in front of the computer

Bloodshot eyes due to lifestyle and environmental irritants may disappear on their own, or you can try to relieve them with over-the-counter eye drops or liquid tears. Lifestyle changes, such as getting more sleep, cutting down on alcohol intake and limiting screen time can often be helpful. If allergies are the culprit, oral antihistamines and antihistamine eye drops may relieve symptoms.

At other times, underlying problems requiring prompt medical attention can cause your eye’s blood vessels to dilate. The following are some of these medical conditions:

Conjunctivitis

You’ve probably heard of “pink eye.” It’s another name for infectious conjunctivitis – an infection of the conjunctiva, the thin membrane covering the eyelid and the front surface of the eye.

There are two types of infectious conjunctivitis – bacterial and viral.

If your child has conjunctivitis, they’re not alone. About 12% of kids get bacterial conjunctivitis every year. This highly contagious condition affects children and adults. In addition to reddish eyes, the following symptoms are associated with conjunctivitis:

  • Bacterial conjunctivitis – irritated eyes, swollen eyelids, eye discharge, crusty eyelids and excessive tearing
  • Viral conjunctivitis – cold or flu-like symptoms, runny nose, fever, itchy eyes, excessive tearing

If you or your child are experiencing these symptoms, it’s important to schedule a prompt appointment with an eye doctor, who can diagnose whether the conjunctivitis is viral, bacterial or due to allergies.

Depending on the diagnosis, your eye doctor will prescribe antibiotic eye drops or creams to treat bacterial conjunctivitis. The viral form may run its course after a few days, but cold compresses and non-prescription eye drops may provide relief.

Dry Eye Syndrome

If your eyes are chronically bloodshot you may have dry eye syndrome (DES). Signs of DES include:

  • Dry, irritated eyes
  • Burning or stinging eyes
  • Discharge from the eyes
  • Light sensitivity
  • A feeling you have something stuck in your eyes
  • Blurred vision
  • Watery eyes

Dry eye syndrome is most commonly caused by a blockage of the tiny meibomian glands in the eyelids. These glands secrete oil that keeps eye moisture from evaporating too quickly. Without the oil, tears dry fast, leaving your eyes feeling dry, itchy and with a bloodshot appearance.

Too much screen time, aging, certain medications such as antihistamines, and medical conditions such as Sjogren’s syndrome can cause dry eye syndrome.

In addition to any medications or in-office treatments your eye doctor recommends, make sure to get plenty of hydration, take frequent breaks from digital screens and use a humidifier in your home.

Uveitis

In addition to bloodshot eyes, if you also experience blurred vision, see floaters or your eyes feel painful, you may have an eye inflammation called uveitis. The causes of uveitis include:

  • Autoimmune or inflammatory condition
  • Infection
  • Medication side effects
  • Cancer (in rare cases)

Unfortunately, uveitis symptoms can often be mistaken for something less serious. That’s the reason it’s important to get an eye exam if your eyes are bloodshot. Left untreated, uveitis can lead to serious conditions such as retinal scarring, cataracts and vision loss.

Depending on the cause and severity, your eye doctor may treat uveitis with prescription eye drops, steroid pills, injections or eye implants.

Eye Injury

It’s vital that all eye injuries receive immediate eye care from an eye doctor.

Even a minor eye injury can cause a big red blotch to form on the white part of the eye (sclera). The cause is a broken blood vessel or a subconjunctival hemorrhage.

Although the appearance of this blood looks severe, and can make the entire white part of the eye appear bright red, a subconjunctival hemorrhage is usually painless and doesn’t cause vision loss. Any time you notice excessive blood on the eye following an eye injury, schedule an appointment with an eye doctor to assess the health of your eye.

Glaucoma

In rare cases, bloodshot eyes may signal the presence of glaucoma – a leading cause of vision loss and blindness.

While some types of glaucoma don’t show symptoms in the early phases, bloodshot eyes can indicate the type of glaucoma that requires immediate medical care. This disease causes damage to the optic nerve due to excessive pressure within the eye. When this pressure suddenly rises, the eye’s blood vessels become dilated and visible, making the eye appear red.

If you have bloodshot eyes and/or have the following risk factors for glaucoma, immediately schedule an appointment with your eye doctor.

  • Family history of glaucoma
  • Aged 60+
  • African American, Asian or Hispanic
  • Diabetes
  • High blood pressure

Bloodshot Eyes Won’t Go Away?

Talk to Us Any time you notice bloodshot eyes or blood on the front of the eye, don’t wait. Schedule your eye exam with Dr. Laura Di Nino at Dr. Laura Di Nino in Markham today.

Q&A With Your Local Optometrist

Can I get bloodshot eyes after LASIK surgery?

LASIK surgery is highly effective minimally invasive laser eye surgery that can correct refractive errors, but like all surgical procedures, it can have side effects. Your eyes may be bloodshot or you could see halos from a few days to three weeks after surgery. Additionally, you may experience other dry eye symptoms. Eye drops and liquid tears can alleviate these symptoms, but if you have any concerns about your eyes following LASIK surgery contact your eye surgeon.

What Should I Expect from a Glaucoma Exam?

If you have a family history and/or other risk factors for glaucoma, and if your eyes look bloodshot, consider scheduling a glaucoma exam. Your eye doctor may perform the following tests:

  • Tonometry – eye pressure test
  • Gonioscopy – to see how fluid is draining out of your eye
  • Vision field test – to examine the functioning of the optic nerve
  • Dilated pupil exam – to detect any damage to the optic nerve
  • Retinal photo or OCT – digital examination of the retina and optic nerve health

Can Cholesterol Affect Your Eyes?

When you think about high cholesterol, what do you think of? Most people would say something like “heart problem” or “cardiovascular disease.” But did you know that high levels of cholesterol can also have an effect on your body that goes beyond your heart? You may be surprised that high cholesterol can also have an impact on your eyes.

Keywords:

High Cholesterol and Your Eyes

Xanthelasma (Fatty deposits) in your eyelid
The most common way that your eyes can be affected is through the presence of xanthelasma. These are small yellow-tinted deposits of fat in the skin around your eyes, specifically, in the upper eyelids and inside the eyelids, around the area of the nose.

Risk factors and causes of xanthelasma
Not everyone who has high cholesterol develops xanthelasma, but more than 50% of people who have xanthelasma have high cholesterol.

Some of the risk factors for xanthelasma include:

  • Heavy drinking.
  • Heart disease.
  • Smoking.
  • Pancreatitis.
  • Obesity.
  • Conditions caused by xanthelasma

Usually xanthelasma isn’t painful. Though it’s usually just an issue of looks, xanthelasma can sometimes get worse, causing more serious problems.

Arcus senilis is a condition in which a white or grayish ring or halo appears around the edges of the clear layer of your eye that protects your iris, known as the cornea.

This ring comes from cholesterol deposits in your eye, which don’t impair your vision, but are still a definite sign of issues with high cholesterol which need to be addressed with your doctor.

Hollenhorst plaque is a much more serious issue than arcus senilis. This occurs when small pieces of plaque build-up that result from high cholesterol break loose from the blood vessel walls, travel up to the vessels in the eye, and get stuck there, blocking blood flow in one or more of the blood vessels within your eye. This can lead to potentially severe consequences for your vision, including vision loss and even blindness.

Increased risk of eye diseases and conditions

Along with the immediate signs of high cholesterol that are present in the form of xanthelasma and associated eye conditions, there is also an increased risk of developing several sight-threatening eye conditions, including:

  • Macular degeneration
  • Glaucoma
  • Myopia
  • Treating cholesterol conditions in your eyes
  • Treating these and other eye conditions that result from high cholesterol requires a holistic approach that considers the whole body, One of the most effective ways to address these problems is to adopt a low-fat diet. This includes eating more unprocessed fruits and vegetables and avoiding foods that are highly processed, such as potato chips and simple carbs.

In some cases, your doctor may also prescribe certain medications to help lower cholesterol including:

  • Statins (Atorvastatin, Fluvastatin and Lovastatin).
  • Bile acid sequestrants (Cholestyramine, Colestipol, Colesevelam).
  • PCSK9 Inhibitors (Alirocumab, Evolocumab).

Though they may not cause you any pain, these eye symptoms can still do damage to your vision, and are also a sign of an overall issue with your health. Don’t ignore the signs of high cholesterol.

Types of Eye Exams

With technology making life more and more convenient every day, there’s a growing trend toward online healthcare appointments. And eye care is no different. But what exactly can you get out of an online eye care appointment, and what should you still expect to visit your Markham eye doctor in person for? Let’s find out!

Keywords:

Online/App Based Appointments

These appointments are ideal for people on the go who are not suffering from any particular vision issues or symptoms. They are meant as a convenient way to update stable prescriptions for young adults between the ages of 18 and 40 who have no eye health issues and are experiencing no change in their vision. No eye doctor is present for these kinds of appointments.

Telehealth Visits

These appointments offer a face-to-face meeting with your eye doctor online, usually through a specialized telehealth service optimized for your privacy. They are for patients who may already be established with the practice or have complaints related to the outside of the eye or the eyelids, such as a black eye or stye. Nonetheless, even a telehealth appointment with the highest-quality webcam can’t give your eye doctor nearly as much information as they can get from high-resolution imaging equipment in-office.

In-Person Comprehensive Eye Exams

This is the most thorough type of eye exam. It allows your eye doctor to utilize the latest eye care technology to measure your level of refractive error, test your inner eye pressure to check for signs of glaucoma, take images and scans of your retina to guard against retinal detachment and macular degeneration, and more.

Many potentially sight-threatening conditions show no signs or symptoms until significant damage to the eye has already been done. These conditions can only be detected with a thorough in-person eye exam.

Effective Tips for Reducing Computer Vision Symptoms

In this day and age, you simply can’t escape the glow of smartphones, tablets, computers, and TVs. Unfortunately, this can have some very damaging effects on your eyes.

Keywords:

After a full day in front of screens, many people report experiencing symptoms such as eye strain, light sensitivity, and headaches. All of these have been linked to extended screen time, and are often referred to as computer vision syndrome.

These symptoms can be especially bad for those with myopia (nearsightedness), hyperopia (farsightedness), or astigmatism.

Since many of us need these screens for school and work, we don’t have the luxury of significantly reducing our daily screen time. Nonetheless, there are still many creative ways to reduce the painful and uncomfortable effects of extended digital screen usage.

Here are four effective ways to minimize eye fatigue and other computer vision symptoms.

Ask about ways to reduce blue light exposure

One of the most common unseen problems with digital screens is blue light exposure. Though blue light is natural, and even healthy for your eyes in moderation, excessive amounts like that experienced from long hours on screens can cause issues with sleeping and result in strain on your retina that has been linked to an increased risk of long-term retina damage.

One easy and inexpensive way to reduce the effects of blue light on your eyes is by asking your eye doctor during your annual eye exam about anti-glare and anti-blue light coatings for your glasses. Many electronics stores will also sell blue light filters for your computer and other digital screens.

Try the “20-20-20 Rule.

Research shows that spending long hours concentrating on computer work significantly decreases the number of blinks you take per minute, leading to dry, red, itchy eyes.

Try the “20-20-20 Break and Blink Rule” to help increase the number of blinks you take while working. Every 20 minutes in front of your computer, look at an object 20 ft away from you for 20 seconds and blink. This gives your eyes a chance to “reset” before continuing to work and helps prevent eye strain, dry eyes, and headaches.

Take Eye Health Supplements.

Eye health supplements contain healthy and essential nutrients and vitamins and minerals that can help reduce the harmful effects of digital screens. Zeaxanthin and Lutein are anti-oxidants found in many supplements that can’t be naturally produced in the body and help protect the macula from blue light damage.

High-quality eye health supplements can reduce computer vision symptoms, as well as minimize the long-term risk of developing eye conditions such as cataracts and macular degeneration.

Lubricate your eyes.

Naturally, our eyes lubricate themselves by blinking. However, because of the reduced rate of blinking mentioned earlier, eyes tend to dry out faster while concentrating on digital screens.

One way to combat this is by the use of lubricating drops or artificial tears. Though over-the-counter eye drops are easy to obtain, it’s always better to speak to your eye doctor to get the best advice on what will help you the most. In many cases, prescription eye drops or artificial tears will be much more effective.

For more information on how you can reduce eye strain and other symptoms of computer vision syndrome, speak to our eye care professionals at today!

What’s Your Optometrist Role in Cataract Surgery?

If you’re over the age of 60, there’s a good chance you’ll develop cataracts sometime in the next 20 or so years. While the only effective long-term treatment for cataracts is surgery, it can take years or even decades for a cataract to reach the point where it needs to be surgically removed.

In the meantime, your optometrist can monitor its progression, manage your symptoms and ensure you have the best vision possible. Once your cataract makes it difficult for you to function day-to-day, your eye doctor will refer you to an ophthalmologist who will perform eye surgery to replace your eye’s natural lens with a clear artificial lens.

Following your surgery, your optometrist will co-manage your post-op recovery in coordination with your eye surgeon.

Your Optometrist Will Discuss Cataract Treatment Options

A cataract, a clouding of the eye’s natural lens caused by the breakdown of proteins in the lens, leads to progressively blurry vision. So if you’ve been diagnosed with a cataract but aren’t yet ready for surgery, you’ll be having regular contact with your optometrist, who will explain the condition, discuss your treatment options and help manage your symptoms.

Once you’re diagnosed with cataracts, you may want to slow the progression of the condition. Working with an optometrist who knows your personal and family health history as well as your various options for cataract management and surgery is a massive advantage, as your optometrist can give you advice on dietary and lifestyle changes.

The Importance of Regular Eye Exams

Regular eye exams are important for everyone, and particularly if you’ve been diagnosed with cataracts. Because the cloudy areas on your eye lenses will worsen with time, your optometrist will carefully monitor your vision and upgrade your glasses or contact lens prescription as needed. Your optometrist will perform a visual acuity test and other tests to gauge increased sensitivity to light and glare, as well as deterioration in your contrast and color vision.

When’s It Time for Cataract Surgery?

At some point, your optometrist may determine that your cataracts are severe enough to require surgery. That’s typically when options to correct your vision — updated prescriptions and speciality filters that block glare and increase contrast vision — are no longer sufficient to give you the vision you need.

Your optometrist can recommend an ophthalmologist and provide information about what to expect during cataract surgery. You’ll see your eye surgeon for post-surgery check-ups, and your optometrist for long-term eye care.

If your vision is blurred or if you notice a cloudy patch forming on your eye, you may have developed cataracts. For optimal vision care and cataract management, make sure to schedule an appointment with Dr. Laura Di Nino at Dr. Laura Di Nino in Markham today.

What’s the best treatment for cataracts?

Although many people use glasses to manage cataract symptoms and improve their deteriorating vision, the only way to really treat cataracts is via surgery. You may want to delay the procedure, but once your quality of life is affected to the degree that it’s difficult to drive or perform everyday tasks, it’s time to have cataract surgery.

Will cataracts return after surgery?

Generally, no. Because the eye’s natural lens is removed and replaced with an artificial one during cataract surgery, a cataract can’t return to that eye. That said, there’s a possibility that a few years after the surgery, you may need a quick laser procedure if the proteins on the lens capsule — the layer that holds the artificial lens in place — becomes cloudy.

5 Vision-Saving Tips for National Save Your Vision Month

March is here. And you know what that means…

It’s National Save Your Vision Month!

In honor of this special month, which not only signals the start of spring but reminds us to protect our eyes, we’ve put together a list of 5 essential ways that you can ‘save your vision.’

It goes without saying that routine eye exams are a top priority when it comes to taking care of your eyes, so here are 5 additional things you can do to keep your eyes healthy and your vision clear.

1. Maintain a Healthy Diet

You’re likely aware that a balanced diet consists of all different types of nutritious foods that contain the vitamins and nutrients you need to keep your body healthy and strong.

But did you know that certain foods actually promote eye health and can lower your risk of eye disease?

Eating foods that are high in omega-3 fatty acids, lutein and zeaxanthin, as well as vitamins A, B, C and E, can protect your eye health and help save your vision from sight-threatening eye diseases, like age-related macular degeneration (AMD), diabetic retinopathy and glaucoma.

If you don’t think your daily meals offer enough of these essential vitamins and nutrients, ask your doctor whether you should add a daily supplement to your diet.

2. Limit Screen Time

The digital world has created a new venue for working, communicating, socializing and entertainment. But it’s also brought about a new eye condition called computer vision syndrome (CVS) — also called digital eye strain (DES) — that’s a growing concern among eye care professionals.

Not only can too much screen time affect productivity in work and school, but it can also result in dry, red, irritated eyes, blurry vision, headaches, neck, back and shoulder pain, and even have a negative effect on your mood and quality of sleep.

So this month, take it upon yourself to be more aware of how much time you spend in front of a digital screen, and try to set boundaries whenever possible for you and your children. You can also practice the 20-20-20 rule — every 20 minutes, look at something at least 20 feet away for a minimum of 20 seconds.

3. Use Protective Eyewear

Every day, thousands of people receive emergency care for an eye-related accident — many of them resulting in permanent damage and vision loss.

The best way to protect yourself and your loved ones is by wearing protective eyewear for all activities that pose an eye health risk — from sports and water gun fights to lightsaber tournaments and science experiments. And, of course, this also implies any type of home-improvement project that involves small particles like grass, saw dust or metal flying into your eye.

Protective eyewear can truly save your vision.

 

4. Wear Sunglasses All Year Round

Sunglasses are more than just a fashion accessory to enhance your look. They shield your eyes from the sun’s harmful UV rays, which can damage your vision and lead to serious eye diseases like cataracts and macular degeneration.

Now you have an even better excuse to go out and buy yourself the new pair of shades you’ve been dreaming about. Just make sure they offer 100% UV protection.

Wear your new sunglasses all year round, even on cloudy and snowy days, because the sun’s UV rays can penetrate the clouds and reflect off the snow-covered ground, doubling your exposure.

5. Quit Smoking

If you’ve been thinking about quitting, now’s the time! Smoking is not only dangerous for your overall health, it increases your risk for sight-threatening eye diseases like glaucoma, diabetic retinopathy, age-related macular degeneration and cataracts.

So, for the sake of your vision and overall health, take the first steps toward kicking your smoking habit.

In honor of National Save Your Vision Month, why not try some of these vision-saving habits that can help you keep your eyes and vision healthy for a lifetime. Your future self will thank you.

Do children need to wear sunglasses?

Yes, sunglasses are essential for protecting your child’s eyes both now and in the future. A child’s eyes are still maturing and are therefore even more susceptible to UV damage than adults. Encourage your child to wear sunglasses whenever they play outside by setting a good example and making sure to wear sunglasses whenever you venture outdoors.

What are sports goggles?

Sports goggles are a type of protective eyewear worn by many athletes. These goggles contain impact resistant, durable polycarbonate lenses, offering the ultimate eye protection during sports activities. If you or your child play sports, sports goggles are an essential accessory to your athletic gear.
