The lenses are scratch-resistant true color glass, meaning the grey lenses do not distort the colors you see through them. They also offer 100% UV protection, protecting your eyes from the sun's harmful rays. As you can see, the ear pieces are bayonet style, making them easy to put on and off while wearing a helmet. Available in your choice of gold, black or chrome frames in 52mm or 57mm lenses. Ships with balck protective case.
