Health Tip: Why Wear Sunglasses?
They block sun's ultraviolet rays
(HealthDay News) -- Well-made sunglasses do more than make you look like a movie star. They can protect your eyes from many problems, including those caused by the sun's harmful rays.
The American Optometric Association says you should always don sunglasses during the daylight hours because:
- They protect your eyes against the sun's UV rays, which could otherwise lead to cataracts.
- They protect against "blue light" from the solar spectrum, which could increase your risk of macular degeneration.
- They lead to improved and more comfortable vision from not having to squint.
- They can make it easier to adapt to darkness. Exposure to bright light can make it more difficult to adjust to driving at night.
