How can they harm thee? Let us count the ways.
Catchin' some rays ain't always what it is cracked up to be, especially if they are UV rays. These rays don't sing but they can play a tune on your eyes if you are not careful. There are three basic types of UV radiation: UV A Rays- May produce severe reactions to all layers of the cornea. UV B rays May cause permanent cataracts. All UV C Rays- May produce photokeratitis.(welder's flash). Almost all industrial safety glasses are 99.9% UV A and B protected. Only specialized industrial safety glasses meet UV C standards. That's why it is wise to wear safety glasses when both at work or play.
