Driving sunglasses are copper colored or amber color lenses that filter out up to 100% of UVA/B Rays. The copper amber color filters out blue light which gives you clearer vision and keeps things bright. Copper/Amber driving sunglasses can be worn earlier in the day, in the early evening or on cloudy days. If you live in an area where haze is a problem, driving sunglasses will ceate a clearer vision. Non polarized copper amber color driving sunglasses are also a favorite of many pilots.
