Wearing sunglasses year-round isn’t such a bad idea.
During the winter, sunlight glare can reflect off the snow, ice and water into your eyes, which in-turn can cause UV damage.
"We're getting just as much UV light exposure right now, maybe even more than in the summer," said Dr. Sara Starko, an optometrist at Fort Saskatchewan Eyecare. "Even on a cloudy day you're getting some UV exposure."
Exposure to winter sunlight and glare can cause squinting, eye strain, and at times headaches. In some circumstances it can create various eye diseases including cataracts.
Sunglasses also help protect from the cold wind and snow-related particles.
Sunglasses should be worn by all ages.
"People usually overlook the fact that their children need sunglasses when in fact UV damage is cumulative over a lifetime," said Dr. Starko. "Even children out on the playground at recess should have sunglasses on."
People with lighter-coloured eyes are at a greater risk of UV damage as the iris lets in more light.
Cheap sunglasses will help, but quality glasses will better protect against the harmful UV rays.
