Sunglasses can be a great accessory to your style or sense of fashion, but more importantly sunglasses serve a functional purpose: they protect your eyes. Just what do sunglasses protect your eyes from? Harmful ultra violet rays which can damage your eyes and even impair your vision. According to the American Ophthalmic Association harmful UV rays can cause cataracts, cancer of the eyelids, growths on the eye’s surface, or even “snow blindness”. Not only do UV rays come directly from the sun, but they can also reflect from glare on various surfaces such as water, snow, or even ice. Polarized sunglasses have special lenses that combat glare that regular “UV-treated” lenses cannot.
Why Wear Sunglasses in the Winter?
While it may not look “as sunny” in the winter, there are just as many harmful UV rays reaching your eyes if you do not wear polarized sunglasses. Winter also brings ice and snow, two things that UV rays can reflect off of to cause even more harmful effects. Glare from ice and snow can also be extremely dangerous if you are operating machinery like a snowmobile or even simply driving your car. Polarized sunglasses will not only protect your eyes from UV rays and glare, but will make your surroundings more clear.
This winter season, don’t forget your polarized sunglasses. Just because it may not look as sunny as it would in the dog days of summer, that does not mean that there are not harmful UV rays or glare. Polarized lenses cut down glare and reflections from UV rays which can impair your vision and eyesight.
