Yellow tinted lenses increase contrast and depth perception making these ideal for shooting as they filter out the somewhat scattered, out-of-focus blue light from the scene so we perceive a brighter scene and have better perception of depth. The aerodynamic shatterproof polycarbonate one piece wrap around lenses give excellent peripheral vision whilst offering the utmost protection from the suns harmful rays and also flying objects. An anti fog coating is applied to both sides of the lens to help deter lens fogging. The glasses also wrap around to ensure they stay put. Shatterproof Polycarbonate Lenses are standard as with all our range so to afford maximum protection whilst decentred lenses give optimum optical quality. A free microfiber storage pouch is included and doubles as a safe lens cleaning clothe when turned inside out.
