Never before has eye protection looked so good and felt so natural. The 3M Lexa lens curves around the face to appear virtually invisible to the wearer while providing optimum, full coverage. Lexa eyewear is available in two lens sizes, and the already comfortable fit can be fine-tuned by adjusting the lens angle, temple length and Easy-Change Lens. Lexa features DX Anti-Fog Lens Coating to resist fogging, scratching, static and chemical attack.
