Many Canadians love basking in the sun during the long awaited summer months, but they’re not taking enough precautions to protect their eyes from damaging UV rays that can lead to cataracts, one of the four leading eye diseases. In time for UV Safety Awareness Month, a joint survey from the Canadian Ophthalmological Society and the Canadian Association of Optometrists reveals that just two-thirds of Canadians regularly wear sunglasses on a sunny day (64 per cent) or during the summer months (63 per cent), and only 33 per cent wear them all year long. If left untreated, cataracts can cause blindness.

“It’s important to protect our eyes from harmful UV rays all year long to decrease the risk of developing cataracts later in life,” says Dr. Phil Hooper, President of the Canadian Ophthalmological Society. “While this eye disease is more common in people over 60, young people are still at risk, so taking the necessary precaution now will only help decrease their chances of getting this eye disease in the future.”

The survey also revealed that younger Canadians may not be taking enough precaution in protecting their eyes from harmful UV rays. Only a third of respondents say that their children regularly wear sunglasses on a sunny day (33 per cent) or during the summer months (32 per cent), and only 13 per cent say their children wear them on a cloudy day, despite the fact that UV rays are still present.

Cataract is a clouding of the natural lens inside the eye which focuses the light on the back of the eye, and makes your vision blurry. They usually develop slowly, causing a gradual and painless decrease in vision. Some vision problems that cataracts can produce include: blurry vision, glare (particularly at night), frequent changes in eyeglass prescription, a decrease in colour intensity, or a  yellowing of images.

Over 2.5 million people in Canada are living with cataracts, and while the eye disease is most common in people over the age of 60, changes to the lens generally start around the age of 40. To determine if you have cataracts, your eye doctor will ask you about your medical history and the symptoms you have. They will also perform an eye exam and conduct a few tests:

  • Visual acuity test: This test helps your eye doctor see if you’ve had any worsening in your vision. You’ll be asked to look at an eye chart with different sizes of letters on it. Your doctor will test one eye at a time, with the other eye covered.
  • Slit-lamp examination: A slit lamp allows your eye doctor to view different parts of your eye (cornea, iris and lens) up close to see if there are any problems. This device is called a “slit lamp” because it uses a bright line of light to illuminate the different parts of your eye.
