How to Pick Good Sunglasses
Here's tips for choosing shades that will protect your eyes from the sun's harmful effects.
Sunglasses can give you instant James Dean cool, Audrey Hepburn glamour, or the rock star hipness of Bono. But they are much more than a fashion accessory. Sunglasses are an essential tool in safeguarding the health of your eyes and the surrounding tissue. Here's what you need to know about what sunglasses can do for you (apart from style) and how to choose them.
UV radiation increases your odds of getting cataracts, which cloud the eye’s lens and lead to diminished eyesight. It has also been linked to macular degeneration, a treatable, but incurable disease of the macula, a part of the retina that is essential for sharp vision.
Other UV-related eye problems are pterygium and pingueculum. A pterygium occurs when the conjunctiva, the tissue that lays over the white of the eye, grows into the cornea. A pingueculum is a yellowish bump of tissue on the white of the eye.
Sunlight that bounces off highly reflective surfaces such as snow, water, sand, or pavement can be especially dangerous.
