I bought these to use with an open face helmet and prescription glasses while riding a motorcycle. While not cheap they are far and away the best goggles I've ever come across. The optics are perfect with both clear and smoked lens. They go over glasses well with absolutely no fogging under all conditions I've encountered so far. Though large, they look good when used with my Rockhard helmet.
