These glasses are a revelation. Comfortable, lightweight, indestructible, and they give me clear vision close up as well as at medium range. I'm very active and can't be fiddling with my glasses all the time. If I had to come up with a critique, it's that the lenses are slightly large for my face (I'm a petite woman), but they have a sort of "safety glasses chic" that I find appealing. If you are on the fence, don't hesitate. You'll be glad you got these glasses.
