Sunglasses protect your eyes from UVA and UVB rays.
For the best protection:
- Buy sunglasses that filter out both kinds of rays, they don't have to be expensive. Look for a label that specifically states 99 percent or 100 percent UV protection. An eye care pro can test them if you're unsure.
- Sunglasses should be dark enough to reduce glare but not dark enough to distort colors, which could affect your recognition of traffic signals. Tint is a matter of personal preference.
- Pick out a pair of sunglasses that look good under a hat. Since UV rays can still enter from the sides and top of sunglasses, it's smart to wear a hat with a three-inch brim to help block light.
The most active muscles in your body are the ones in your eyes. Your eyes have over 2 million working parts and the ability to process 36,000 bits of information every hour. Your eyes are always moving, even when they're not open. That makes your eyes one of your body's most powerful tools. Be sure to take care of your eyes.
