What You Should Know About Night Blindness

If you don’t see well while driving at night, there’s a chance you have night blindness. Night blindness, or nyctalopia, is the inability to see well at night or in dim lighting. It’s not considered an eye disease, but rather a symptom of an underlying problem.  

Our eye doctor can help diagnose, manage and treat your night blindness so that you can enjoy being out at night again. 

Here are 4 things you should know about night blindness:

Causes of Night Blindness 

The inability to see well at night can be the result of a condition such as:

Vitamin A Deficiency — Vitamin A helps keep your cornea, the layer at the front of your eye, clear; it’s also an important component of rhodopsin, a protein that enables you to see in low light conditions. Although uncommon in North America, deficiency of this vitamin can induce night blindness. 

Cataracts — A buildup of protein clouds the eye’s lens, leading to impaired vision, especially at night and in poor lighting conditions.

Diabetic Retinopathy — Damage to the eyes’ blood vessels and nerves can result in vision loss, including difficulty seeing at night.  

Glaucoma — This group of eye diseases is associated with pressure build-up in the eye that damages the optic nerve. Both glaucoma and the medications used to treat it can cause night blindness. 

Myopia — Also called nearsightedness, myopia makes distant objects appear blurry, and patients with it describe a starburst effect around lights at night.

Keratoconus — An irregularly shaped cornea causes blurred vision and may involve sensitivity to light and glare which tend to be worse at night.

Retinitis Pigmentosa (RP) — A progressive genetic eye disease which can be associated with other diseases, RP leads to night blindness and peripheral vision loss.

Usher Syndrome — This genetic condition causes both hearing loss and vision loss, including night blindness and RP, mentioned above.

Symptoms of Nyctalopia

Since night blindness is a symptom of some serious vision problems, it’s important to get your eyes checked regularly to ensure that everything is in good working order. Contact your eye doctor as soon as possible if you notice that you don’t see as well in dim light as you used to, such as when driving at night or when adjusting from being outdoors in the sunshine to being indoors. 

Symptoms of Night Blindness Include:

  • Reduced contrast sensitivity
  • Difficulty seeing people outdoors at night
  • Difficulty seeing in places with dim lighting, like a movie theater
  • Trouble adapting to the dark while driving
  • Excessive squinting at night 
  • Trouble adjusting from bright areas to darker ones 

Treatments for Night Blindness

Your eye doctor will want to diagnose the cause of your night blindness in order to treat it. For example, in the rare case of vitamin A deficiency, it can be treated with vitamin supplements and vitamin-A rich foods; myopia can be corrected with eyeglasses or contact lenses. Other conditions may require medications or surgery. 

If night blindness is caused by a birth defect, Usher syndrome, or retinitis pigmentosa, low vision aids and devices can help you make the most of your remaining vision. 

Prevention

While there is no proven way to prevent night blindness resulting from genetic conditions or birth defects, consuming healthy, nourishing foods and taking certain vitamin supplements may prevent or slow the onset of some eye conditions that cause night blindness.

Are Contact Lenses Safe For Young Children?

Here’s a question we often get at our practice: ‘Is my child too young for contact lenses?’ This is an important question, and the answer may surprise you. 

For children with myopia (nearsightedness), contact lenses can be a convenient method of vision correction. It allows kids to go about their day without having to worry about breaking or misplacing their glasses, and enables them to freely participate in sports and other physical activities. 

Some children and young teens may ask their parents for contact lenses because they feel self-conscious wearing glasses. Contact lenses may even provide children with the confidence boost they need to come out of their shell. Moreover, these days, it is very popular for children to wear single-use one-day disposable soft contacts, since there is no cleaning or maintenance involved. 

Some parents may deny their child’s request for contacts due to concerns about eye health and safety. There’s no reason to worry: contact lenses are just as safe for children as they are for anyone else. 

At Pickering Town Centre Optometric Clinic, we provide children, teens, and patients of all ages with a wide variety of contact lenses. If you’re concerned about the safety of contacts for your child, we’ll be happy to explain and explore ways to ensure maximum safety, optimal eye health and comfort. To learn more or to schedule a pediatric eye exam for contact lenses, contact us today. 

What Are the Risks of Having My Child Wear Contact Lenses?

A study published in the January 2021 issue of The Journal of Ophthalmic & Physiological Optics found that kids aren’t at a higher risk of experiencing contact lens complications. 

The study followed nearly 1000 children aged 8-16 over the course of 1.5-3 years to determine how contact lenses affected their eye health. 

The results indicate that age doesn’t have an effect on contact lens safety. In fact, the researchers found that the risk of developing infections or other adverse reactions was less than 1% per year of wear — which is comparable to contact lens wearers of other ages.

But before you decide that contact lenses are right for your child, you may want to consider whether your child is ready to wear them. During his or her eye doctor’s appointment, the optometrist may ask about your child’s level of maturity, responsibility, and personal hygiene. Since many children are highly motivated to wear contacts, they tend to display real maturity in caring for their lenses. That said, in the initial stages, parents may need to play an active role, as their child gets used to inserting and removing the new contact lenses.  

It’s important to note that just as with any other medical device, contact lenses are not risk-free. Anyone who wears contact lenses has a chance of developing eye infections or other complications with contact lenses. However, when worn and cared for according to your eye doctor’s instructions, contact lenses are low-risk and perfectly safe for children and teenagers.

So, go ahead and bring your child in for a contact lens consultation! We’ll help determine if your child is ready for contacts and answer any questions you or your child may have. To schedule your child’s contact lens fitting or eye exam, contact Pickering Town Centre Optometric Clinic in Pickering today.  

6 Common Myths About Glaucoma

Glaucoma is an eye disease in which increased pressure causes progressive, permanent vision loss and even blindness. Unfortunately, many misconceptions about the disease can leave you misinformed. Below we sort fact from fiction by debunking 6 of the most common glaucoma myths.

Glaucoma Facts vs. Myths

MYTH 1: Glaucoma is a single disease

FACT 

Glaucoma is a group of eye diseases; the most common ones are open-angle glaucoma (OAG) and angle-closure glaucoma (ACG). 

In open-angle glaucoma, the drainage structure in your eye (called the trabecular meshwork) doesn’t allow the fluid inside the eye to flow out as it should, causing an increase in internal ocular pressure that damages the optic nerve. OAG develops slowly, and usually by the time people perceive symptoms, such as peripheral vision loss, they already have optic nerve damage. 

In angle-closure glaucoma, the eye doesn’t drain fluid as it should because the drainage channel between your iris and cornea becomes too narrow, causing increased eye pressure. This pressure damages the optic nerve, leading to vision loss. ACG can occur suddenly or gradually.

MYTH 2: Only the elderly suffer from glaucoma

FACT

Although it’s true that people over 60 are at a greater risk of developing open-angle glaucoma compared to people in their 40s, there are other types of glaucoma that can affect people aged 20 to 50 and even young infants (due to abnormal ocular development). 

In addition to age, those with a higher risk of developing glaucoma include:

  • African Americans and Hispanics 
  • Individuals with a family history of glaucoma 
  • Patients with cardiovascular disease, diabetes, or sickle cell anemia
  • Those who have previously sustained an eye injury
  • People taking steroid medications over the long term

MYTH 3: Glaucoma shows symptoms early on

FACT

The most common form of glaucoma, open-angle glaucoma, shows virtually no signs or symptoms until its later stages when vision loss sets in. Despite what people may think, the increased eye pressure causes no pain. And since peripheral vision is the first to go, you may not recognize vision loss until your vision has become significantly impaired. The only way to detect glaucoma is to undergo a comprehensive eye exam. 

MYTH 4: Nothing can be done once you have glaucoma

FACT 

While there’s currently no cure for glaucoma, many effective treatment options exist: eye drops, oral medications, as well as laser and surgical procedures that can help slow glaucoma progression. Each treatment option is used to get the fluid to flow properly out of the eye, reducing pressure inside the eye and decreasing damage to the optic nerve.

MYTH 5: Testing for glaucoma is painful

FACT 

Actually, testing for glaucoma is practically painless. One of the tests includes a non-contact device that blows a gentle puff of air into each eye to test the intraocular pressure. The sound of the puff may be startling, but it’s over in a second and is painless. With the Goldmann applanation tonometry test, an anesthetic eye drop is inserted into each eye, which may cause a stinging sensation for a few seconds. Your eye doctor will then use a blue light to quickly and gently touch the cornea to precisely measure intraocular pressure. The most accurate of all, however, are visual field testing and OCT (optical coherence tomography), non-invasive imaging, both of which are also painless.

MYTH 6: You can’t prevent glaucoma

FACT 

Regular eye exams are the only way to prevent glaucoma, as blindness or significant vision loss can be prevented if the disease is diagnosed and treated in the early stages. That’s why routine comprehensive eye exams which include glaucoma testing are so important.

Getting your eyes checked regularly can ensure that any existing eye problems are detected early enough to prevent or slow ocular damage. Contact Pickering Town Centre Optometric Clinic in Pickering to book your comprehensive eye exam today!

The Importance of Eye Exams for Contact Lenses

Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe, providing you with the right lenses for you. 

What is a contact lens exam?

If you wear or want to wear contact lenses, you’ll need an eye exam for contact lenses, in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts. 

Are eyeglass prescriptions the same as contact lens prescriptions?

No, a prescription for glasses cannot be used for contact lenses. An eyeglass prescription is for lenses that are positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye.

The prescription for contact lenses also includes the brand, lens diameter and curvature, which are not part of an eyeglass prescription.

Contact lenses fitting: One size does not fit all

One contact lens size doesn’t fit all eyes. If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes. 

Corneal curvature

This measures the curvature of your eye’s clear front surface (cornea) so the eye doctor can select the optimal curve and diameter for your contact lenses. If your eye’s surface is somewhat irregular because of astigmatism or other conditions, you may require a special lens. 

Pupil and iris size

The size of your pupil and iris (the colored part of your eye) is also important in determining the best contact lens design.

Tear film evaluation

This test evaluates the quality of your tears, to determine whether they will be able to keep contact lenses and your cornea sufficiently hydrated throughout the day. If you have dry eye disease, standard contact lenses may not be right for you. 

Trial lenses

Following the eye exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This will allow the eye doctor to make any fine adjustments to the prescription.

Contact Lens Eye Exam Near You

Wearing the correct contact lenses for your eyes allows you to enjoy all of the benefits of wearing contacts, while keeping your eyes healthy and comfortable. 

If you’re already a contact lens wearer, visit your eye doctor at least once a year to make sure the lenses are still providing you with optimum vision and comfort.

8 Ways Your Eyes Change With Age

Our eyes and vision change with age. Your eye doctor can monitor these changes — some of which are a natural part of the aging process — and identify any eye conditions or diseases early enough to treat them and prevent vision loss. Read on to learn more about the different types of eye changes one may encounter with age.

Age-Related Eye Conditions and Diseases

Cataracts

If your vision is starting to get blurry, you may be developing cataracts. There are a few types of cataracts, but the one usually caused by aging is known as a “nuclear cataract”. At first, it may lead to increased nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and clouds your vision. As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color, and left untreated, it can eventually lead to blindness. Luckily, cataract surgery, where the cloudy lens is replaced with a clear lens, is an extremely safe and effective treatment option. 

Blepharoptosis

Blepharoptosis or ptosis is a drooping of the upper eyelid that may affect one or both eyes. The eyelid may droop only slightly or may droop enough to cover the pupil and block vision. It occurs when there is a weakness of the eye’s levator muscle that lifts the eyelid. This condition is usually caused by aging, eye surgery, or disease affecting the muscle or its nerve. Fortunately, blepharoptosis can be corrected with surgery.

Vitreous detachment

This occurs when the gel-like vitreous fluid inside the eye begins to liquefy and pull away from the retina, causing “spots and floaters” and, sometimes, flashes of light. This occurrence is usually harmless, but floaters and flashes of light can also signal the beginning of a detached retina — a serious problem that can cause blindness, and requires immediate treatment. If you experience sudden or worsening flashes and increased floaters, see Dr. Anthony Cheung immediately to determine the cause.

Other Age-Related Changes

In addition to the above eye conditions and diseases, the structure of our eyes and vision change as we get older. 

Presbyopia

Why do people in their 40s and 50s have more difficulty focusing on near objects like books and phone screens? The lens inside the eye begins to lose its ability to change shape and bring near objects into focus, a process is called presbyopia. Over time, presbyopia, also known as age-related farsightedness, will become more pronounced and you will eventually need reading glasses to see clearly. You may need multiple prescriptions – one prescription to enable you to see up close, one for intermediate distance, and one for distance vision. In that case, people often get bifocals, multifocals or PALs, and they can be combined with contact lenses as well.

Reduced pupil size

As we age, our reaction to light and the muscles that control our pupil size lose some strength. This causes the pupil to become smaller and less responsive to changes in ambient lighting. The result? It becomes harder to clearly see objects, such as a menu, in a low-light setting like a restaurant.  

Dry eye

Our tear glands produce fewer tears and the tears they produce have less moisturizing oils. Your eye doctor can determine whether your dry eye is age-related or due to another condition, and will recommend the right over-the-counter or prescription eye drops, or other effective and lasting treatments, to alleviate the dryness and restore comfort.

Loss of peripheral vision

Aging causes a 1-3 degree loss of peripheral vision per decade of life. In fact, one may reach a peripheral visual field loss of 20-30 degrees by the time they reach their 70s and 80s. While peripheral vision loss is a normal part of aging, it can also indicate the presence of a serious eye disease, like glaucoma. The best way to ascertain the cause is by getting an eye exam. 

Decreased color vision

The cells in the retina responsible for normal color vision tend to decline as we age, causing colors to become less bright and the contrast between different colors to be less noticeable. Though a normal part of aging, faded colors can at times signal a more serious ocular problem. 

Beyond the normal changes that come with age, the risk of developing a serious eye disease, such as age related macular degeneration and glaucoma, increases. Routine eye exams are essential to keeping your eyes healthy. Your eye doctor can determine whether your symptoms are caused by an eye problem or are a normal byproduct of aging. 

If you or a loved one suffers from impaired vision, we can help. To find out more and to schedule your annual eye doctor’s appointment, contact Pickering Town Centre Optometric Clinic in Pickering today. 

Protect Your Eyes From Vision Loss: Diabetes Awareness Month

What Is Diabetic Retinopathy?

Diabetic Retinopathy (DR) is one of the most prevalent eye diseases affecting the working age population. It is thought to be caused by high blood sugar levels which, over time, damage the tiny blood vessels of the retina at the back of the eye, making them swell and leak. Left untreated, DR can lead to vision loss and eventually blindness.

Since diabetic eye disease is typically painless and shows no symptoms until its advanced stages, it’s critical to get your annual eye evaluation, as an optometrist can detect the developing signs early enough to prevent vision loss.

Symptoms of Diabetic Retinopathy 

Diabetics may not realize they have diabetic retinopathy, because it develops silently. As the condition worsens, it may cause: 

  • Blurred vision
  • Poor night vision
  • Colors to appear faded or washed out
  • An increased presence of floaters
  • Vision loss
  • Blank or dark areas in your field of vision

Diabetic retinopathy symptoms usually affect both eyes.

Risk Factors

If you are diabetic, caring for your eyes by undergoing routine eye exams and taking care of your body by controlling blood sugar levels are critical to preventing vision loss. There are several risk factors associated with diabetic eye complications, including: 

  • Poor blood sugar control
  • Smoking
  • High cholesterol 
  • High blood pressure
  • Pregnancy
  • Excess weight/obesity

Are There Any Treatments for Diabetic Retinopathy?

Today’s treatment options may improve your vision, even if you feel your eyesight has begun to deteriorate. Medications can be injected to reduce swelling, and laser surgery can be used to shrink and seal off swollen and leaking blood vessels — preserving and, in many cases, even improving vision. 

While certain treatments may work, frequent monitoring of your eyes coupled with managing your blood sugar levels can go a long way toward preventing or reducing diabetic retinopathy complications. 

If You Have Diabetes, Make Sure to: 

  • Control blood sugar and blood pressure to prevent long-term damage to the fine blood vessels within the retina.  
  • Keep a healthy lifestyle routine, especially during stressful times such as the COVID-19 pandemic. (Plus, while diabetics are in the high-risk category, your chances of developing serious COVID-19 related complications is lower if your diabetes is under control.)
  • Maintain a steady diet and exercise regimen to help the body and mind feel better. 
  • Quit smoking, if applicable; you can reach out to a medical professional for guidance.
  • Get yearly diabetic eye exams.

Preventing and managing diabetic retinopathy require a multi-disciplinary approach involving your eye doctor and other medical professionals. Your eye doctor will perform a comprehensive eye exam to determine whether you have diabetic retinopathy, assess its severity, and discuss preventative strategies as well as the latest treatment options.

New To Contact Lenses? Here Are Our Top 5 Tips!

For an estimated 56 million North Americans, contact lenses are the preferred form of vision correction. So if you’ve just started wearing contact lenses — you’re in good company.

Advice About Contact Lenses from Pickering Eye Doctor: Dr. Anthony Cheung

Here are 5 tips to quickly help you adjust to wearing and caring for your new lenses so you can enjoy the many benefits they offer.

  1. Learn How to Tell if Your Contact Lens Is Inside Out

This is a common mistake many beginners make when inserting soft contacts. Place the lens on  your index fingertip and look carefully at its shape. The edge of the lens should be pointing upwards, like the rim of a teacup. If the edge is flared outward like a blooming flower, the lens is inside out.

Some contact lenses have tiny laser markings of numbers or letters. If the numbers/letters read correctly when you hold the lens on your fingertip, they are properly oriented and the lens is ready to be inserted.

  1. Never Use a Substitute for Contact Lens Solution

Your eye doctor will recommend the appropriate contact lens solution to suit your eyes and lenses. Some people have sensitivities and not all lens solutions are the same. 

Even if you run out of contact lens solution, don’t be tempted to rinse your lenses with water, and never use saliva to moisten or clean them.

Using substances other than the recommended contact lens solution to rinse or rewet your contacts can introduce harmful microbes to the eye and cause a serious infection. That’s why it’s best to remove your contacts before showering, swimming, or any other time they might get wet.

  1. If Your Contact Lenses Feel Uncomfortable, Take Them Out!

Some newcomers mistakenly think that if their contacts feel uncomfortable or gritty, they simply need to “get used to them.” Contact lenses are supposed to be comfortable, so if you are experiencing discomfort there may be something wrong.

With clean fingers, remove your contacts and rinse them, inside and out, with the solution or rewetting drops as recommended by your eye doctor. Dust or dirt could have gotten stuck between the lens and your eye, causing irritation. Flushing the lenses with contact lens solution will help remove the irritant.

If your eyes still feel irritated, don’t place the contact lenses back in your eyes. Instead, wait until they are no longer red or irritated, and try inserting them again. If the problem persists, contact your eye doctor.

  1. Wear Contact Lens-Friendly Makeup

Wearing makeup around the eyes can be a source of irritation and infection whether you wear contact lenses or not. Here’s what we recommend when it comes to eye makeup and contact lenses:

  • Choose hypoallergenic makeup.
  • If using a cream-based product around your eyes, choose a water-based formula instead of an oil-based one. 
  • Keep your eye closed during application to avoid makeup particles entering your eye. 
  • Don’t apply eyeliner or eyeshadow to the inner rims of your eyelids.
  • Replace eye makeup at least once every 3 months to minimize the growth and spread of bacteria.
  • Never share eye makeup with friends or family.
  • Remove your contact lenses before removing your makeup.
  1. Stick to the Hygiene Guidelines

We can’t emphasize this enough — always thoroughly wash and dry your hands before handling your contact lenses.

Try to avoid washing your hands with oily or heavily scented hand soaps, as they tend to cling to the surface of the lens and could irritate the eye. Additionally, if you touch moisturizers or lotions before handling your contact lenses you run the risk of some residual product adhering to the lens and clouding your vision.

After washing your hands, dry them using a lint-free towel. It’s harder to grasp contact lenses with wet hands, and — as mentioned above — lenses shouldn’t come into contact with tap water.

Bonus Tip: Get an Eye Exam

While all this advice can be very helpful, it doesn’t replace an in-person exam with your eye doctor.  Your eye doctor will advise you when to return for your next contact lens consultation. Following this schedule is the best way to ensure you can enjoy the freedom of contact lens wear.

If you are new to contact lenses (or not!) and have any questions or concerns about your eyes or vision, call 905-492-1898. Pickering Town Centre Optometric Clinic will be happy to schedule you for a contact lens exam and fitting.

With the help of Dr. Anthony Cheung, you’ll be an expert in contact lens wear and care in no time!

5 Reasons To Wear Sunglasses In The Fall

When we think of fall accessories, the first things that come to mind are warm sweaters, plush scarves, or a snug pair of boots. Here’s another essential item to add to your list: a good quality pair of UV-blocking sunglasses. 

But why is it so important to protect your eyes when the sun seems to be hiding behind clouds on most days? While it may not make much sense, you’ll get a better understanding by the time you finish reading this article. So let’s dive in and explore the 5 reasons you should protect your eyes from the sun in the fall. 

Sunglasses: Summer Vs. Fall

The Sun’s Position

While we may squint more in the summer, the sunlight’s path to the eyes is more direct in the fall as the sun sits closer to the horizon. This places our eyes at greater risk of overexposure to UV rays. 

Changing Temperatures 

Irritating symptoms like dry, red, or watery eyes are often due to the season’s cool and harsh winds. The colder the air, the stiffer and thicker the eyes’ tear oils (meibum) become. Because thicker meibum doesn’t spread as evenly over the surface of the eyes, the tears can’t offer sufficient protection and moisture. 

Minimize irritation by shielding the eyes from cool winds with wraparound sunglasses.

UV Rays 

Exposing your eyes to the sun’s harmful ultraviolet (UV) rays is problematic year-round, as it can result in serious eye diseases, such as cataracts and macular degeneration. That’s why it’s important to wear 100% UV-blocking sunglasses anytime you’re outdoors, no matter the season.

Make sure to sport your sunnies even on cloudy days, as up to 90% of UV rays pass through clouds. Furthermore, outdoor objects like concrete and snow reflect a significant amount of UV rays into the eyes. 

Fall’s Dangerous Sun Glare 

Because the sun is positioned at a lower angle in the fall, it can produce a brutal glare that poses a danger for driving. Rays of light that reflect off of smooth surfaces like the metal of nearby cars can be so bright to the point of blinding the driver.  

You can combat this dangerous glare by wearing polarized sunglasses. These lenses reduce the glare’s harmful effects by filtering out horizontal light waves, such as the ones reflected by a shiny car bumper. 

Protection From the Elements

Aside from its drying effects, winds can carry dust, debris, and pollutants that can irritate the delicate areas in and around the eyes. Wear sunglasses to shield and block out irritants and certain allergens that drift in the autumn air.

Looking for Sunglasses Near You?

Here’s the bottom line: you need to protect your eyes by wearing sunglasses in the fall and year-round, no matter the season or climate. Investing in a stylish pair of durable, UV-protective sunglasses is — simply-put — a worthwhile investment in your eye health.

So if you’re looking for advice about a new pair of high-quality sunglasses for the fall, with or without prescription lenses, visit Pickering Town Centre Optometric Clinic. If standard sunglass lenses are too dark for you at this time of year, ask us about green or brown tinted lenses; they transmit more light and contrast to the eyes than standard grey tints.  

We’ll be happy to help you find that perfect pair to protect your eyes, suit your lifestyle needs and enhance your personal style. To learn more, call 905-492-1898 to contact our Pickering eye doctor today.

The Best Foods for Your Eyes

We all know that eating nutrient-rich foods, drinking plenty of water, and exercising can boost our health. So it’s no surprise that these same activities also support eye health. Research has shown that regularly consuming certain vitamins and nutrients can actually prevent or delay sight-threatening eye conditions and diseases such as macular degeneration, cataracts, and glaucoma. 

Here’s a list of the best vitamins, minerals, and nutrients that can help keep your eyes healthy for a lifetime. 

We invite you to consult with our eye doctor, Dr. Anthony Cheung, to discuss which nutrients are most suited to your specific eye health and needs. 

Vitamins and Nutrients That Support Eye Health

*Always best to speak with your primary care doctor before taking any vitamins or supplements, and to ensure you consume the correct dosage for your body.

Vitamin A

Vitamin A deficiency can cause a host of eye health issues, including dry eyes and night blindness. In fact, vitamin A deficiency is a leading cause of blindness worldwide.

Vitamins A and A1, which are essential for supporting the eye’s photoreceptors (the light-sensing cells) in the retina, can be found in foods like carrots, leafy greens, egg yolks, liver, and fish. 

Omega-3 Fatty Acids

Eating Omega-3 rich foods like fatty fish can support eye health in a few ways. DHA and EPA, 2 different types of Omega-3 fatty acids, have been shown to improve retinal function and visual development.  

Omega-3 supplements can also ease dry eye symptoms. A randomized controlled study found that people who consumed Omega-3 supplements experienced improved tear quality, which resulted in reduced tear evaporation and increased eye comfort.  

Lutein and Zeaxanthin

Lutein and zeaxanthin are antioxidants that accumulate in the lens and retina and help filter out damaging UV rays and blue light. One study showed that individuals who had the highest levels of these nutrients in their diets had a 43% lower chance of developing macular degeneration than those who had consumed the least amount.  

Spinach, egg yolks, sweet corn, and red grapes are some of the foods that contain high levels of lutein and zeaxanthin. 

Vitamin C 

High amounts of vitamin C can be found in the aqueous humor of the eye, the liquid that fills the eye’s anterior chamber and supports corneal integrity. This has prompted scientists to consider this vitamin’s role in protecting eye health. 

Research suggests that regularly taking vitamin C (along with other essential vitamins and minerals) can lower the risk of developing cataracts, and slow the progression of age-related macular degeneration and visual acuity loss.

While vitamin C appears to support eye health in a variety of ways, it’s still unclear whether taking this supplement benefits those who aren’t deficient. Vitamin C can be found in various fruits and vegetables, like bell peppers, tomatoes, citrus fruits, broccoli, and kale. 

Vitamin E

Vitamin E is an antioxidant that helps protect fatty acids from becoming oxidized. Because the retina has a high concentration of fatty acids, sufficient vitamin E intake is crucial for optimal ocular health. 

Vitamin E can be found in almonds, flaxseed oil, and sunflower seeds. 

Zinc

Healthy eyes naturally contain high levels of zinc. A zinc deficiency can cause night blindness, and thus increasing zinc intake can improve night vision. Zinc also helps absorb Vitamin A, an essential antioxidant. 

Make sure to avoid taking high doses of zinc (beyond 100 mg daily) without first consulting your eye doctor. Higher doses of zinc have been associated with side effects such as reduced immune function. You can increase your zinc intake naturally by consuming more oysters, meat, and peanuts. 

Phytochemical Antioxidants

Phytochemical antioxidants are chemicals produced by plants that contain several health benefits. Some studies show that these plant-based chemicals may enhance vision and eye health as well as prevent age-related eye diseases and complications by alleviating ocular oxidative stress. Oxidative stress within the eyes contributes to several eye conditions, including  dry eye syndrome. Consuming more produce with these antioxidants can help balance the anti-oxidant and pro-oxidant system, resulting in healthier eyes. 

Personalized Eye Nutrition 

If you or someone you know is looking for ways to boost or maintain eye health, speak with an optometrist near you about what supplements and vitamins are best for you. For an eye doctor in Pickering, give us a call at 905-492-1898.

 

How Can My Child’s Myopia Be Corrected?

At Pickering Town Centre Optometric Clinic, we help children like yours achieve clear and comfortable vision, so they can succeed at the important things in life.

Methods of Myopia Correction

Contact Lenses 

Contacts can be a great choice, especially for physically active children or teens who don’t want to worry about breaking or misplacing their eyeglasses. In some cases of very high myopia, contact lenses can offer clearer vision than glasses. 

Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. There are several types, including: soft contacts, daily disposables, extended wear, and rigid gas permeable (hard) lenses. Navigating through the differences between them can be daunting. Fortunately, if you’re located in Pickering our eye doctor will be happy to guide you. Speak with Dr. Anthony Cheung to determine whether your child is ready for contact lenses. 

Prescription Glasses 

Glasses are a popular choice among our younger patients. Choosing from an array of styles makes the process fun and exciting! Allowing the children to be active participants in selecting their eyewear increases the likelihood that they’ll actually wear them. There are strong, flexible and resilient frames which look great and are comfortable too.

The optician can customize the lenses with additions and upgrades like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun. For those requiring vision correction for distance and near, we also offer bifocal or multifocal lens prescriptions. 

We Can Help Correct Your Child’s Myopia 

If you’re located near Pickering, Ontario, an eye exam with our optometrist can determine your child’s exact prescription, and give you the opportunity to receive answers to any questions you may have about your child’s eye health and vision. Progressive myopia, where a growing child’s prescription continues to worsen, is why it’s important for myopic children to undergo eye exams at least once a year. 

At Pickering Town Centre Optometric Clinic, our friendly and knowledgeable staff will be happy to recommend the most suitable method of correcting your child’s myopia to meet his or her individual needs. Thanks to the wide range options available, your child will walk away with eyewear that will not only enhance his or her style but will also be a boost of confidence. 

Let us help your child see the world in a whole new light. To schedule your child’s annual eye exam or if you have any further questions, contact Pickering Town Centre Optometric Clinic at 905-492-1898 today. 

WE ARE OPEN!

Due to Covid-19 we have taken extensive measures to keep our staff and patients safe. Please call or email ptcoptometricclinic@gmail.com prior to coming in so that we can book a time and notify you of our safety protocols in order to maintain social distancing.

If you need to order your contact lenses please call or email us and we will ship them to you directly. If you prefer, our Optometrists are still offering virtual eye care when possible.

We ask that if you or someone you live with has been ill in the last 14 days, you have traveled outside Canada in the last 14 days and/or you have been diagnosed/exposed to COVID-19 in the last 30 days that you refrain from making an appointment at this time.

*Please note our Sunday hours have been tentatively changed to match the current mall hours of 11-5pm.

Thank you for making our clinic a safe space.
