I haven't used them much, but there are some fine scratches on the lenses. I think they're not very noticeable. The part that goes over the left ear is loose and wobbly because the screw is loose. I don't have a small screwdriver to tighten it, but it's better to tighten the screw before using them. They come with a case. They are unisex. Both men and women can use them.
