On summer days, eyes can get "sunburned," too - overexposure can cause pain, irritation and temporarily impaired vision.
Eye-care professionals say sunglasses that protect against ultraviolet radiation are essential. Look for:- Lenses treated to filter out UV-A and UV-B rays.
- Close-fitting or wraparound sunglasses that don't allow unfiltered light to seep around the lenses.
- Lenses that are shatter-resistant.
- Polarized lenses to help reduce reflection and glare if you drive a lot or are active near the water.
