Snow Blindness: A Hidden Winter Eye Risk
When we think about protecting our eyes from the sun, most of us picture summer days at the lake. But here in Fort McMurray, winter can actually pose a serious UV risk to your eyes.
Itās called snow blindness ā and itās more common than you might think.
What Is Snow Blindness?
Snow blindness, also known as photokeratitis, is essentially a sunburn on the surface of your eye. It happens when UV rays reflect off snow and ice and damage the cornea.
Fresh snow can reflect up to 80% of UV rays. That means even on cloudy or cold days, your eyes may still be exposed to high levels of ultraviolet light.
Just because itās freezing outside doesnāt mean UV rays arenāt strong.
Symptoms of Snow Blindness
Symptoms donāt always appear immediately. They often show up several hours after exposure and may include:
- Pain or burning in the eyes
- Redness
- Sensitivity to light
- Blurred vision
- A gritty or āsand in the eyeā feeling
- Excessive tearing
In most cases, it heals within 24ā48 hours, but it can be very uncomfortable ā and repeated exposure increases long-term risk.
Who Is Most at Risk in Winter?
- People who snowmobile or ski
- Outdoor workers
- Children playing outside for extended periods
- Anyone driving long distances on bright snowy roads
Even everyday errands on bright winter afternoons can expose your eyes to intense reflected sunlight.
How to Protect Your Eyes This Winter
1. Wear Proper UV-Protective Sunglasses
Not all sunglasses are created equal. Look for lenses labeled 100% UV protection. Dark lenses without UV protection can actually make exposure worse by allowing your pupils to dilate.
2. Consider Polarized Lenses
Polarized lenses help reduce glare ā which is especially helpful when sunlight reflects off snow and ice.
3. Donāt Forget the Kids
Childrenās eyes are more sensitive to UV exposure. If your kids are outside for long winter days, sunglasses are just as important as mittens.
4. Ask About Prescription Sunglasses
If you wear glasses, prescription sunglasses give you both clear vision and UV protection ā without compromising comfort.
Why Winter Eye Protection Matters Long-Term
Repeated UV exposure over time increases the risk of:
- Cataracts
- Macular degeneration
- Growths on the eyeās surface (such as pterygium)
Protecting your eyes in winter isnāt just about comfort ā itās about long-term vision health.
