There is no excuse for not using protective eyewear while hunting. All our shooting glasses use HD SPEX Ballistx Diamond Vision lenses that are made of a bullet-proof lens material. Traditional shooting glasses use tinted polycarbonate yellow, rose, or orange lenses that wash the background and everything you see all one color. HD SPEX does not tint lenses. Our Diamond Vision Ballistx lenses provide rich, vibrant, high definition color images in the field that provide perfect depth of field utilizing HD SPEX proprietary ColorTrast lens technology. ColorTrast is a vivid color enhancing and high contrast lens technology that produces high definition imaging. Whether you’re waterfowling or shooting driven pheasant, our lens technologies give you perfect registration of game with zero distortion and 100% protection for the suns harmful UV rays. Both Plano and Prescription.
