We all know that running can help keep our heart healthy. But did you know that it can also help protect your eyes?
Recent research, which will be published in the journal of Medicine & Science in Sports & Science, reports that the more fit and active a person is, the less likely they are to develop glaucoma!

The study analyzed data from more than 9,500 people between the ages of 40 and 81. The researchers compared each individual's aerobic fitness and their average amount of weekly exercise to how many subjects developed glaucoma during the 6 year follow up period.

The researchers found that those who were most active and fittest had ONLY HALF the risk of developing glaucoma as the least active group.

So, just in case you needed another reason to get active... Now you know that getting regular exercise doesn't just keep your heart health, it can also protect your eyes!

As always, if you have any questions or concerns about your vision or health, please get in touch!

Protection Young Eyes

Protecting-young-eyes.jpg

Perhaps the most commonly asked question by parents of young children is, "how much screen time should they be allowed"?

Until recently, there were no specific guidelines on how much time children should be spending on screens. Fortunately, based on research and date collected over the last few years, the Canadian Association of Optometrists and the Canadian Opthalmological Society have released their suggestions for safe screen use among children.

These days, screens of all types (TV, computer, tablet, phone) are everywhere. They are, for the most part, unavoidable. As such, it's not surprising that we have seen a significant increase in nearsightedness in the younger population. A 2016 study by the University of Waterloo stated that the combination of more screen time and less time outdoors was resulting in 29 percent of children between age 11 and 13 to be nearsighted.

Another report, from a survey done in 2014 on 200 American children, found that 80 percent of participants reported burning, itchy, or tired eyes after using digital devices.

Based on the literature review, the Canadian Association of Optometrists and Canadian Ophthalmological Society say the safe use of electronic screens should encompass the following:

Screen time limits – no screen time (with the possible exception of live video chatting with parental support) for children aged two and under, no more than one hour of screen time per day for kids aged two to five and ideally no more than two hours per day of recreational screen time for children aged five to 18;

Breaks, which include whole-body physical activity, no later than after 60 minutes of use (after 30 minutes is encouraged);

Workstation ergonomics – set chair heights so the child’s feet can lay flat on the floor or on a stool underneath the feet to allow for support, chairs should not have arm rests unless they fit the child perfectly, desks should be set at the child’s elbow height or slightly lower, there should be enough depth on the desk to allow for forearm support, displays should be set in front of the child, the top of computer monitors should be at the child’s eye level and then allow them to move the screen down into a comfortable viewing position as needed and workstation lighting should be equal throughout the visual field;

Screens should not be used within an hour of bedtime or in the bedroom;

Outdoor activity over screen time should be encouraged; and

Regular eye exams, which assess a child’s visual ability to cope with their visual demands and offer treatments for deficiencies.

As always, we are very happy to see children for their routine eye exams as well as any time other concerns may arise with the vision or eye health.

Did you know...

In addition to helping detect, treat and prevent eye diseases, most doctors of optometry provide care for urgent eye health issues like infections (ie. pink eye), inflammation (ie. blepharitis), allergies and eye injuries, including removing foreign bodies from the eye. As trained specialists, optometrists can assess unusual or sudden vision changes and various conditions causing eye pain and, when necessary, provide referrals to other specialists.

Do you need a referral?

No, you do not need a referral, and in most cases we see you on the same day.

What are the most common urgent eye care issues?

The most common issues are pink eye, redness, allergies, eye infections and inflammation, abrasions, and foreign objects stuck in the eye.

What are some common symptoms of eye infections?

Common symptoms include:

  • Redness
  • Pain
  • Discharge
  • Itching
  • Blurry Vision
  • Light sensitivity
  • Swelling

Where do most eye injuries occur?

  • 44% occur at home
  • 16% occur at work
  • 14% at school or other
  • 15% during sports and recreation
  • 11% on the road

If you or anyone in your family has an urgent issue or is experiencing some of the symptoms listed above, you can call usbook an appointment online, or walk in.

Vision Health Month

20180503_201036000_iOS.png

May is Vision Health Month so we thought we'd take a minute to chat about eye health and the amazing things that can be seen during the eye health portion of your eye exam.

We've all heard the saying that "the eyes are the windows to the soul". But, the truth is that they are actually the windows to our health!
During a routine, comprehensive eye exam, it is not unusual for your Doctor of Optometry to notice signs related to systemic conditions such as high blood pressure, diabetes, and cholesterol.

Aside from testing your vision and determining your glasses/contact lens prescriptions, we are always sure to take a very close look at the internal health of your eyes as well.

Did you know, the optic nerve in the back of the eye is actually an extension of the brain? 

This means that in some cases, we are able to detect serious issues such as brain tumours, multiple sclerosis, and others by evaluating this part of the eye closely.

Did you know, the retinal blood vessels in the back of the eye are directly related to the blood vessels in the brain and are only a few branches away from the heart? 

The eye is the only place in the body that we can see our blood vessels in their natural environment. This is how, by looking into the eye, we can detect conditions that are associated with the heart such as blood pressure and cholesterol.

So, don't forget to get your eyes checked regularly so we can make sure you have clear vision and health eyes!

Surviving Allergy Season

Spring has officially arrived which means allergy season is here – or quickly approaching. If you’re amongst the 8 million Canadians (one-quarter of the country) that has seasonal allergies, you’ve probably experienced some form of itchy, red, dry, or watery eyes.

Seasonal allergies are caused by the high pollen released by trees, grass, outdoor moulds, and ragweed. They begin in the spring, peak in the summer, and can last as late as fall.

Most of us know when seasonal allergies strike because we start to experience mild to extreme discomfort in our eyes, but have you ever wondered what’s actually causing our eyes to react? Dr. Harleen Takhar explains:

"Allergens in the air bind to receptors (called mast cells). We have approximately 50 million of these receptors on the surface of our eyes.

When the mast cells come in contact with the allergens, they release a chemical called histamine, which is what ultimately causes our eyes to feel itchy and watery. It also causes the blood vessels on the surface of our eyes dilate, which makes our eyes look red."

Most allergens are seasonal, which in most cases last between four to six weeks.

Here are the best -and safest- ways to manage your eyes this allergy season:

  • Get in the habit of checking your local pollen forecast, which provides you with a daily outlook on the types and severity of pollen in the air.
  • Speak with us about over-the-counter or prescription eye drops if discomfort persists.
  • Place cold compresses on your eyes, this can help relieve the itching sensation.
  • Despite temptation, DO NOT RUB YOUR EYES, as this will only make your eyes worse and can potentially cause long-term damage.

If you’re experiencing persistent eye discomfort as a result of seasonal allergies, be sure to book an appointment with us to discuss your options.

10 Fascinating Facts About Your Eyes

They've been called the window to the soul. But your eyes are also one of the most unique parts of your body, with over 2 million individual components, making them the second most complex organ... after the human brain.

Here are 10 other strange-but-true facts about your eyes.

1. You See the World Upside Down & Split in Half
When you first view an object, the image is actually processed by your eyes upside down (not unlike how the mirror in an old fashioned camera works). What's more, the image is split in half and distorted. Your retina flips the image, matches the two pieces together and clears up the distortion before sending the visual signal to your brain—with all of this occurring in nano seconds.

2. You Blink 9 Million Times a Year
On average you blink 17 times each minute. That works out to nearly 25,000 blinks a day and over 9 million blinks a year. Your eye also happens to be the fastest muscle in your body, which is how a single blink can happen in less than four-tenthsof a second—all of which may explain the old saying "in the blink of an eye."

3. Your Retinas Can't See Red
The receptors in your retina that process colours are actually only capable of detecting yellow-green and blue-green combinations. Your brain combines these different signals and identifies colours that are missing as being red. 

4. Different Things Produce Different Tears
While the main purpose of tears is to remove dirt and harmful bacteria from the eyes, research has found that our tears are actually chemically different depending on the situation. Scientists have found that "reflex tears" (such as those caused by allergies or getting something in your eye) were dramatically different than "emotional tears" (such as those caused by pain or feelings of sadness and joy). In fact, scientists don't really know why we produce tears when we're upset.

5. Your Eyes Are the Same Size Now as When You Were Born
Unlike other parts of your body (such as your nose and ears) your eyes stay basically the same size throughout your life. Scientists speculate that this is because your eyes are so complex that even subtle changes in growth could affect your overall vision. In fact, babies' eyes start to develop in the womb just two weeks after conception takes place.

6. "Red Eye" is Caused by Blood Vessels
Red eye may be the bane of photographers everywhere, but there's actually a fairly simple explanation behind this well-known phenomenon. Red eye occurs because light from the flash of the camera bounces off the back of your eye, hitting the choroid, a layer of tissue located directly behind the retina. The choroid also happens to contain a lot of blood vessels that are captured by the camera and why your eyes end up appearing red on film.

7. Your Eyes Are More Unique Than Your Fingerprints
We often assume that our eyes are similar to other people because we have the same prescription or the same eye colour. In fact, your eyes are incredibly unique. To put this into perspective, your fingerprints have only 40 unique identifying characteristics. Your eyes, on the other hand, have over 256 identifiable characteristics just in your irises alone. This may explain why governments and banks around the world are now looking towards biometric eye scans as a new form of identification. 

8. Only 1/6 of Your Eyeball is Exposed
It turns out that only a small portion of your eyeball is exposed at any given time. That's because a lot of what happens with your vision occurs inside your eyeball and involves millions of sensitive nerves and blood vessels. In fact, human skulls have evolved over the years to offer a maximum amount of protection to the part of your eyes that are unexposed.

9. Your Eyes Process 36,000 Bits of Information Per Hour
It turns out that your eyes are constantly taking in information that's then analyzed by your brain. In fact, researchers estimate that your eye will focus on about 50 objects per second. That's roughly comparable to the amount of data that's processed by a powerful computer.

10. Shark Corneas Are Used in Eye Surgery
It turns out that some of the most successful corneal transplants haven't come from human donors, but rather from sharks. That's because scientists have discovered that shark corneas have thick reinforcing fibres that function much like rebar does in concrete buildings. These fibres strengthen the cornea and prevent it from swelling and turning cloudy, like human corneas can do. In addition to transplanting shark corneas into human patients, scientists have continued to research sharks to understand human eye diseases.

UV Radiation and Your Eyes

Summer is officially upon us and Canadians across the country are excited to get outside and enjoy the sun. While most Canucks recognize the importance of sunscreen to prevent sunburns and skin cancer, many are unaware that UV light can cause serious eye damage. In fact, overexposure to UV rays has been linked to a variety of eye problems, one of which is cataracts, a condition where the normally clear lens of the eye become cloudy and opaque.

June is Cataract Awareness Month, and with an estimated 3.2 million Canadians living with the eye condition, Doctors of Optometry are urging residents to book an annual eye exam with an optometrist and take the necessary precautions to protect your vision from the sun’s harmful rays.  What can you do?

  • Avoid sources for UV radiation. Don’t stare directly at the sun and be aware of reflections from snow, water, sand and pavement. If you’re a welder, hairdresser, lighting technician, paint and resin worker, or work outdoors, be sure you’re in the know about potential risks and how to avoid UV exposure.
  • Protect your peepers. Wear sunglasses that are 100% UV blocking against both UVA and UVB rays, and are close-fitting with a wrap-around style frame to help keep light out. If you wear corrective contact lenses, consider wearing UV-blocking contact lenses for an added layer of UV protection. In addition to cataracts, these steps help protect against:
    • Age-related macular degeneration
    • Eyelid skin cancer
    • Corneal sunburn
    • Age spots
    • Tissue growths on the surface of the eye
  • Stay informed. Get regular eye exams to monitor eye health, maintain good vision and keep up-to-date on the latest in UV protection (Check out the UV Canada smartphone app for up-to-date info on UV radiation in your location).
  • 10-4. Keep out of direct sunlight between 10 a.m. to 4 p.m., when the sun’s rays are strongest.
  • Children are at high risk. It’s estimated that 50% of lifetime exposure to UV happens before the age of 18. Keep children younger than six months out of direct sunlight, ensure children of all ages wear sunglasses and sun hats when outside and consider using a canopy or umbrella as a sun-shield when at the beach or in the back yard.
  • Recognize the symptoms. If you’re experiencing immediate pain, an inflamed cornea, or an aversion to light, see your Doctor of Optometry right away.

Your Doctor of Optometry can make specific recommendations to ensure your eyes are well-protected and to fit you with your perfect pair of sunglasses. Booking a comprehensive eye exam can identify early onset of eye-health conditions related to UV that may not have apparent symptoms.
