+1 to this! As a blue-eyed fellow I find sunglasses to be an absolute necessity. I actually keep two pairs of ANSI-rated safety glasses in my day pack and car; one is charcoal tinted and the other is clear. When I was a kid my dad lost his right eye in a construction accident when a nail head flew into his eye. Cheap safety glasses would have given him almost 40 more years of having both eyes. That lesson was not lost on me.
