We've all seen it before - the landscaper using a line trimmer as it throws rocks, grass and dust, all the while the user is squinting trying to protect their eyes. Or, my favorite, the carpenter using a powered circular saw to rip down a piece of ply wood with their eyes closed. What do both of these examples have in common? They are all "hoping" they don't get anything in their eyes and sustain a nasty injury. It's amazing when people do these types of things, assuming that they won't get hurt. However, the simple addition of a pair of ANSI Z87 rated safety glasses can make a world of difference.
