The FINIS Shockwave Goggles use curved polycarbonate lenses that provide optimal viewing in both indoor and outdoor environments. The smoke style comes with high definition lenses that filter out blue light and improve contrast and depth perception. The clear style gives you the same viewing quality, but does not distort the color indoors. The curved lenses provide a wider angle of vision, while also wrapping comfortably around the face. The Shockwave goggle comes with a silicone split-strap that is threaded through a patented side-button clip for quick and easy adjusting.
