Winter is here but that doesn’t mean your glasses should go into hibernation. “Whether you’re outside to hit the slopes, make a snow angel, string lights or enjoy a vacation, your eyes still need protection,” says Janelle Routhier, OD, FAAO, FBCLA. “While the winter days may be shorter, the sun’s UV rays can still harm your eyes.”
You probably know that too much sun exposure can lead to sunburned skin, but you may not be aware it can also cause sunburn of the eye (called photokeratitis), which can be painful but rarely causes permanent damage. Over exposure to the sun can also cause cataracts, the leading cause of blindness around the world.
If you’re a fan of snow sports, it’s even more crucial that you protect your eyes. Fresh snow reflects nearly 80% of UV radiation, and UV radiation intensity increases 16 percent for every 1,000 meters (3,280 feet) above sea level.
The good news is that Transitions lenses block 100 percent of UVA and UVB rays to give your eyes the protection they need year round.
