Can I Wear Contacts If I Have Astigmatism?

brunette girl smiling 640Many people choose to wear contact lenses to correct their vision due to the freedom and convenience contacts provide. But for those with astigmatism, wearing contact lenses isn’t always simple.

At The Scleral Lens Centre At Village Eye Centre in North Edmonton we offer specialized contact lenses that provide clear and comfortable vision, even if you have moderate to severe astigmatism.

What is Astigmatism?

Astigmatism is a refractive error caused by an irregularly shaped cornea. The abnormal cornea causes light to disperse unevenly into the eye, leading to blurred or distorted vision. Other symptoms of astigmatism can include headaches, eye strain, and difficulties with reading or using digital devices.

Astigmatism may be congenital, meaning that you are born with the condition, or you can develop it later in life. People with astigmatism usually also have myopia (nearsightedness) or hyperopia (farsightedness), two of the most common refractive errors.

Which Contact Lenses Can You Wear With Astigmatism?

Although traditional soft contact lenses may not be suitable for patients with astigmatism, there are two other types of contact lenses specifically designed for those with unusually shaped corneas.

Toric Contact Lenses

Toric lenses are a popular choice for people with mild astigmatism. Patients with higher levels of astigmatism, however, generally require a higher level of expertise.

Toric lenses are designed to provide clear vision and a comfortable fit. There are two main issues with toric lenses. First, the range of corrective powers is limited, so patients with moderate to high levels of astigmatism may not be able to wear toric contacts. Second, these lenses need to rotate on the cornea to find the correct position and orientation, leading these lenses to occasionally provide unstable or varying clarity of vision.

Toric lenses are available in either soft disposable or rigid gas permeable (RGP) lens materials.

Scleral Contact Lenses

Unlike standard lenses, scleral lenses vault over the cornea and sit on the sclera (the white of the eye). These lenses do not have the issues faced by toric lenses as they are individually designed for each patient and do not sit on the cornea. By vaulting over the cornea, scleral lenses create a liquid reservoir between your cornea and the lens. This dome provides a continually hydrating environment that protects the cornea, promotes healing, and increases comfort.

Scleral lenses have become a staple therapeutic tool in the visual rehabilitation of patients with astigmatism and other corneal irregularities. They also can provide better visual acuity than standard soft lenses thanks to their rigid surface and personalized fit. Scleral lenses have proven to be an excellent solution for patients with astigmatism that appreciate sharp and comfortable vision.

How We Can Help

At The Scleral Lens Centre At Village Eye Centre, we can provide you with customized toric or scleral contact lenses that are tailor-made for patients with astigmatism or other corneal irregularities, as well as hard-to-fit eyes. By taking precise and detailed measurements of your cornea, we will be able to ensure a secure fit and crisp, clear vision. To learn more information or to schedule your consultation, call us today.

The Scleral Lens Centre At Village Eye Centre serves patients from Edmonton, Sherwood Park, St. Albert, Fort Saskatchewan, and throughout Alberta.

Glaucoma & Your Eye Health What You Need To Know

Eye Doctor at Village Eye Centre

Eye Doctor at Village Eye Centre

Glaucoma is a leading cause of irreversible blindness in people over the age of 40. In honor of National Glaucoma Awareness Month, here’s what we think you should know about this sight-threatening eye disease.

What Is Glaucoma?

Glaucoma is an eye disease that causes damage to the optic nerve, usually due to high pressure within the eye, called intraocular pressure (IOP). Left untreated, glaucoma can lead to irreversible vision loss, known as ‘tunnel vision,’ and eventually blindness.

The ‘Silent Thief of Sight’

This serious eye condition is known as ‘the silent thief of sight’ as it is often diagnosed too late to avoid irreparable vision loss. This is because glaucoma does not cause pain or any obvious symptoms until the eye has been extensively damaged. The only way to reduce your risk of permanent vision loss is to undergo regular comprehensive eye exams starting from the age of 40, even if you show no symptoms.

Who’s at Risk?

Certain factors can increase your risk of developing glaucoma:

  • Age — your risk of developing glaucoma increases with age. Because this is true for several eye diseases, it is recommended that adults undergo yearly comprehensive eye exams beginning at age 40. This is usually the age when early signs of eye disease are detectable and changes in vision may begin.
  • Family history — people who have a close relative (parent or sibling) with glaucoma are up to 9 times more likely to develop the disease.
  • Nearsightedness — myopia, or nearsightedness, increases a person’s risk of developing glaucoma. The higher the myopia, the higher the risk.
  • Ethnicity — The African American and Hispanic populations are 3 times more likely to have glaucoma than Caucasians. Blindness due to glaucoma is about 6 times more prevalent in African Americans than in Caucasian Americans. Additionally, individuals of Asian heritage have a higher risk of developing angle-closure glaucoma, a sudden and acute form of the eye disease.
  • Other health conditions — Having diabetes puts a person at risk of developing glaucoma, and so does sustaining a previous eye injury.

Is There a Treatment for Glaucoma?

While glaucoma isn’t preventable, patients with glaucoma can undergo treatments to successfully control this condition and prevent vision loss and blindness.

Glaucoma treatments include prescription eye drops, oral medications, and a variety of surgeries that reduce inner-eye pressure. Some procedures involve making small incisions in the eye to help fluid drain more easily, thereby reducing the pressure. Alternatively, small devices known as shunts or stents can be inserted into the eye to increase the flow of the fluid from the eye.

How We Can Help

Here’s a fact about glaucoma that may come as a surprise: half of all people with glaucoma don’t realize they have it! That’s why having yearly comprehensive eye exams is critical to detect underlying eye disease and begin treatment as soon as possible.

At Village Eye Centre, we offer comprehensive eye exams and other eye care services to help keep your eyes feeling and functioning at their best.

To schedule your eye exam, call Village Eye Centre in North Edmonton 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 Village Eye Centre in North Edmonton to book your comprehensive eye exam today!

Frequently Asked Questions with Dr. James Evans

Q: If one of my parents has glaucoma, does that mean I will develop it as well at some point?

  • A: Having a parent with glaucoma does not mean that the child will automatically develop the condition too. However, those people with an immediate family history (parents, siblings) of glaucoma are at more risk to develop this disease. Patients should have a comprehensive eye examination each year to evaluate the health of the eyes and to look for signs of glaucoma. Some of these signs can be an increase in the pressure of the eyes as well as changes to the appearance of the optic nerve. Many times there are no symptoms noticed by the patient. If there is suspicion of glaucoma, more frequent visits to the eye doctor along with additional nerve testing are often required.

Q: Why do I need to scan my retinas/back of the eye?

  • A: The retina shows us a lot about the overall ocular health as well as systemic conditions that can affect the eyes. Often diabetes, hypertension or high cholesterol can be observed from a retinal scan. Also, retinal scans allow us to diagnose and treat macular degeneration and glaucoma. Scans are often very important for a complete eye check up.

Why Do Onions Make Us Cry?

Onions are one of the most common staple foods around the globe. Ironically, for a vegetable so delicious, they can often be tear-jerkers.

Read on to learn why onions cause your eyes to tear and sting, and what you can do to minimize discomfort.

Why Does Cutting Onions Cause Tearing?

Onions produce a sulfur compound called propyl sulfoxide that is stored in the cells of the onion bulb (the part of the onion we eat). Onions grow underground, where they can be eaten by all types of creatures. This odorous sulfuric compound acts as a deterrent to small animals with big appetites.

When one slices into an onion and breaks open its cells, the sulfur compound is released and mixes with the moisture in the air — turning it into smelly and irritating sulfuric acid. When this chemical rises up and comes in contact with your eyes, it stings!

To keep your eyes from potentially being damaged from this chemical exposure, your brain triggers your eyes to tear and flush out the irritating gas particles. Once enough tears have flushed out the sulfuric acids particles from the eye, clear vision and comfort is usually restored. Although your eyes may sting and feel unpleasant, symptoms are temporary and the sulfuric acid won’t damage your eyes.

How Can I Reduce Eye Discomfort When Chopping Onions?

Most experienced chefs will tell you that chilling your onions in the fridge for at least 30 minutes before slicing them will reduce the amount of tearing they cause. Propyl sulfoxide escapes slower in cooler temperatures, reducing the amount of sulfuric acid in the air.

You can also try cutting the onions at arm’s length, or direct the odorous air away with a small fan. Some say that chopping onions immersed in water also helps. Another option is to wear kitchen goggles to protect your eyes.

Furthermore, try to use fresh onions whenever possible. The longer an onion has been stored, the more likely it will induce tearing and discomfort. Try to avoid slicing near the root end of the bulb, as that area has the highest concentration of sulfuric compounds.

Still Having Eye Problems Out of the Kitchen?

If you frequently suffer from eye irritation — and not just while cutting onions — we can help. At Village Eye Centre, we treat a wide range of eye conditions and can provide you with the treatment and relief you seek.

Frequently Asked Questions with Dr. James Evans

Q: What exactly is glaucoma?

  • A: Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

Q: What’s the difference between vision insurance and eye insurance?

  • A: Vision insurance” really isn’t insurance, but rather a benefit that covers some of your costs for eyewear and eye care. It is meant to be used for “routine” care when you aren’t having a problem but want to be sure everything is OK, like having an annual screening exam with your Primary Care Physician. It often, but not always, includes a discount or allowance toward glasses or contact lenses. It is usually a supplemental policy to your medical health insurance. Medical health insurance covers, and must be used when an eye health issue exists. This includes pink eye, eye allergies, glaucoma, floaters, cataracts, diabetes, headaches, and many other conditions. Blurry vision is covered medically if it relates to a medical condition, for example the development of a cataract. For some reason, however, it is considered non-medical if the only finding is the need for glasses or a change of prescription. Of course you can’t know this until you have the exam. In this case, with vision coverage, you would only be responsible for your co-pay, but with medical coverage without vision coverage, you’d be responsible for the usual charge.

Q: How does high blood pressure affect vision?

  • A: If the blood pressure is very high it can be called malignant hypertension and cause swelling of the macula and acute loss of vision. Otherwise hypertension can cause progressive constriction of the arterioles in the eye and other findings. Usually high blood pressure alone will not affect vision much, however hypertension is a known risk factor in the onset and/or progression of other eye disease such as glaucoma, diabetic retinopathy, and macular degeneration as well as blocked veins and arteries in the retina or nerve of the eye that can severely affect vision.

What Can You Expect from Vision Therapy?

When your eyes and brain, which make up your visual system, don’t coordinate properly to give you clear vision, you can experience trouble with everyday tasks such as reading, writing and processing information. Vision therapy can provide effective treatment for this. We provide individualised vision therapy for adults and kids in North Edmonton, Downtown Edmonton and Sherwood Park, Alberta.

What does vision therapy do?

Vision therapy helps to develop the visual skills that are needed for good, comfortable eyesight. Using optical devices and custom-designed exercises, our vision therapists can improve the eye-brain connection, making eye movements more efficient. Both adult and pediatric vision therapy teach the patient how to better process visual information received from the eyes.

Who can benefit from vision therapy?

In general, people who need vision therapy struggle with one or more of the following issues:

  • Strabismus (crossed eyes) or amblyopia
  • Learning-related visual problems, stemming from conditions such as poor skills in eye teaming, focusing, tracking and visualisation
  • Neurological disorder or trauma to the nervous system that affects vision, including traumatic brain injury, strokes, cerebral palsy, developmental delays, multiple sclerosis or whiplash
  • Stress-induced vision problems (eyestrain, headaches), often caused by long periods spent in front of a computer screen
  • Poor sports performance; vision therapy can help athletes by enhancing enhance eye-hand coordination, peripheral awareness, visual reaction time, and a broad range of visual skills

What does vision therapy involve?

In-office and home-based exercises comprise vision therapy for adults and kids. After our eye doctor identifies the particular problem(s), we will design a personalised program geared to improve visual function. Typically, the program will include weekly sessions for several months. At each visit to our eye care centres in North Edmonton, Downtown Edmonton and Sherwood Park, we provide patients with instructions for exercises (20-30 minutes) to do at home until the next appointment. Progress is evaluated continually to determine if more exercises, or a different type, are needed.

What type of results can you expect from vision therapy?

Once the eyes focus, align, move and fixate in tandem, a clearer and more comfortable view of the world is created. While the rate at which people experience improvements varies, some progress is typically seen early in the program of vision therapy sessions.

Many of our adult and pediatric patients in North Edmonton, Downtown Edmonton and Sherwood Park have excitedly reported the following outcomes:

  • Speed and level of reading increases
  • Learning becomes easier, especially for kids in school
  • Ability to follow a moving object, such as on the sports field, improves
  • Less time is spent on homework
  • Objects both nearby and in the distance become sharper

At Village Eye Centre, we put your family’s needs first. Talk to us about how we can help you maintain healthy vision. Call us today: 587-410-5920 or book an appointment online to see one of our North Edmonton eye doctors.

15 Things You Do That Can Harm Your Eyes

Eye health isn’t just about going for that yearly eye exam. Certain actions you take (or don’t take) in your daily routine can also have drastic effects on the health of your eyes and vision. Here’s our list of 15 things you may be doing that could pose damaging risks to your eyes.

It’s important to note that before changing any of your habits, consult with a medical professional to make sure they are right for you and your overall health.

1. Smoking

We all know that smoking can cause heart disease and cancer, but its effects on the eyes are far less known to many. The truth is that smoking can actually lead to irreversible vision loss by significantly increasing the risk of developing macular degeneration, cataracts, glaucoma, and diabetic retinopathy. It can also cause dry eye syndrome. If you are a smoker, do your eyes (and body) a favor and try to kick or reduce the habit.

2. Not Wearing Sunglasses

Exposing your eyes to the sun’s harmful UV radiation can damage the eye’s cornea and lens. Overexposure to UV rays can also lead to cataracts and even eye cancer. That’s why it’s important to always wear 100% UV-blocking sunglasses while outdoors, all four seasons of the year. Always check the sunglasses have FDA approval.

3. Sleeping with Makeup On

When you sleep with eyeliner or mascara, you run the risk of the makeup entering the eye and irritating the cornea. Sleeping with mascara on can introduce harmful bacteria to the eye and cause an infection. Abrasive glitters and shimmery eyeshadow can scratch the cornea as well. Be careful to remove all makeup with an eye-safe makeup remover before going to bed.

4. Buying Decorative Contact Lenses Without a Prescription

Although ordering decorative lenses without first visiting your optometrist may sound more convenient, purchasing them without a prescription isn’t worth the long term risks. Decorative contact lenses are sometimes made by unlicensed manufacturers who tend to use poor-quality or toxic materials that can get absorbed through the eyes into the bloodstream. They also may contain high levels of microorganisms from unsanitary packaging and storage conditions.

5. Not Washing Your Hands Thoroughly

Frequently washing your hands helps to reduce the possibility of bacteria and viruses entering the eye. Pink eye (conjunctivitis) and corneal ulcers are common eye conditions that can be caused by bacteria, viruses, fungi, or parasites. When washing your hands, be sure to use warm water, soap, and thoroughly wash in between each finger and over the entire palm area. If you plan to insert or remove your contact lenses, wash and then dry your hands completely with a lint-free cloth or paper towel.

6. Overwearing Contact Lenses

Wearing contact lenses for longer periods of time than intended can lead to inflammation of the cornea (keratitis), conjunctivitis, eyelid swelling, and contact lens intolerance. Always follow the recommended wear time as instructed by your optometrist.

7. Being Nutrient Deficient

Poor nutrition can cause permanent damage to the visual system. Try to include lots of nutrient-rich fruits and vegetables in your diet, along with adequate amounts of Omega-3. Some of the best vitamins and nutrients for eye health include Vitamins A, C, E, lutein, zeaxanthin, and zinc.

8. Using Non-FDA Approved Products

Whether it’s eyebrow enhancers, eye makeup, or eyelash growth serums, always choose products that have been FDA approved and/or meet government safety regulations. Non-approved products have been known to cause infections or allergic reactions in or around the eye area.

9. Not Cleaning Your Contacts Properly

If you are wearing contact lenses that need to be replaced once every two weeks or once a month, maintaining the highest level of contact lens hygiene is essential. Optometrists will tell you that a common reason patients come in to see them is due to an eye infection from contact lenses that haven’t been properly cleaned or stored. Some patients use their contact lens cases for too long, which can also cause eye irritation. To avoid eye infections, carefully follow your eye doctor’s instructions on how to clean, store, and handle your contact lenses.

10. Showering or Swimming with Contact Lenses

There is a significant amount of bacteria that can be carried in tap water and swimming pools. For this reason, it’s important to make sure that water and contact lenses don’t mix. If you need vision correction while swimming, it may be worth investing in a pair of prescription swimming goggles.

11. Not Following Medication Instructions

When it comes to eye disease, following the medication instructions is crucial. Forgetting to insert eye drops, or administering the incorrect dosage could dramatically reduce the effectiveness of treatment, or even do harm. Speak with your eye doctor if you’re not sure about when or how to take your medication.

12. Not Taking a Holistic Approach

Your eyes are just one part of the whole system — your body. Ignoring health conditions you may have, like high blood pressure or elevated blood sugar, can pose serious risks to your eyes.

13. Not Wearing Protective Eyewear

Shielding your eyes with protective glasses or goggles while working with potentially sharp or fast-moving objects, fragments or particles (wood working, cutting glass, welding, doing repairs with nails, certain sports) is the best defense against eye injury. In fact, 90% of all eye injuries could have been prevented by wearing protective eyewear.

14. Using Unsafe Home Remedies

Some might think that because something is “natural” that it is safe for use around the delicate eye area. Home remedies, like using breastmilk to cure pink eye, could introduce harmful bacteria to the eye and cause infection. If your eyes are giving you trouble, make an appointment to see your local optometrist.

15. Skipping Your Recommended Eye Exam

Your eye doctor will advise you how often you need to come for an eye examination. Adults should visit their eye doctor at least every year for a comprehensive eye exam to determine whether their optical prescription is up-to-date, and to check for the beginning stages of eye disease. Catching eye diseases in their early stages offers the best chance of successful treatment and preserving healthy vision for life.

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.

5 Ways to Set Up Your Home Computer to Reduce Eye Strain

Village Eye Centre | Computer Glasses in North Edmonton

Village Eye Centre | Computer Glasses in North Edmonton

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain — also called computer vision syndrome — according to recent data. Since COVID-19 began, the number of hours spent on a computer for tasks like working from home, online schooling, and online shopping has increased dramatically.

Symptoms of computer eye strain include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes.

If your eyes feel dry and tired, your vision is blurry by the end of the day, or your head, neck, and shoulders ache, the way you utilize your computer and other digital devices might be to blame.

How to Reduce Eye Strain

Spending less time in front of your computer is the best way to reduce digital eye strain, but if you’re working from home or you or your children are learning online, that might not be an option.

Here are 5 steps you can take to lower your risk of eye strain:

1. Use proper lighting

Excessively bright light, either from sunlight or from interior lighting, can cause eye strain.

By reducing exterior light (by closing your drapes, shades or blinds), and tweaking the lighting inside your home (using fewer light bulbs or fluorescent tubes, or lower intensity bulbs and tubes) you can lower glare and reflections off the screen.

Also, if possible, position your computer screen so the windows are to the side, instead of in front or behind it.

2. Blink more often

When staring at a screen, people blink one-third less frequently than they normally do. Blinking moistens your eyes to prevent dryness and irritation.

To reduce your risk of dry eye during computer use, every 20 minutes blink 10 times by closing your eyes very slowly. This will lubricate your eyes and help prevent dry eye.

3. Relax your eyes

Constantly staring at a computer screen can lead to focusing fatigue, which causes digital eye strain. To reduce your risk of tiring your eyes, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds.

Some eye doctors call this the “20-20-20 rule.” Looking far away relaxes the focusing lens inside the eye to reduce fatigue.

4. Take frequent breaks

Taking frequent breaks from your screen can help reduce eye strain and neck, back and shoulder pain during your workday.

It is recommended to take at least one 10-minute break every hour. During these breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to reduce tension and muscle aches.

5. Modify your workstation

Poor posture also contributes to digital eye strain. Adjust your workstation and chair to the correct height so your monitor is not too close to, or too far from your eyes, or in a position that causes you to crane your neck.

Position your computer screen so it’s 20 to 24 inches from your eyes. The center of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck. With this adjustment, you will not only reduce neck, back, and shoulder pain, but reduce eye strain as well.

People experience different levels of digital eye strain, so if after you have shut down your computer the symptoms persist, then you may have a visual problem that requires attention from your eye doctor. If these symptoms are ignored and nothing is done to alleviate the eye strain the problem will only worsen.

Having a yearly checkup can help you preserve your eye health. Contact Village Eye Centre to learn more about how to keep your eyes healthy and reduce eye strain when working on computers.

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. James Evans 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.
