The engineered optics of Lexa eyewear greatly widens the viewing range of the wearer. The sleek style of the Lexa is due to the patented shape, which follows and blends with the facial outline - to provide full coverage and optimum protection. The polycarbonate lenses resist scratches, fogging and chemical attack - thanks in part to the DX anti-fog lens coating. Meets ANSI Z87.1-2003 and CSA Z94.3 standards. Made in USA.
