the polycarbonate lenses are distorion free and give the wearer a clear, bright image when used in cloudy or darkend conditions. They are excellent night driving glasses and are highly recommended for that purpose. They are a good dollar value. They would also make excellent shooting glasses for diminished light conditions and being wraparound, afford maximum protection against stray shot when used on the skeet or trap field. I highly recommend these glases to anyone who wants high quality at an affordable price.
