Photochromic lenses are lenses that darken on exposure to specific types of light, most commonly ultraviolet (UV) radiation. Once the light source is removed (for example by walking indoors), the lenses will gradually return to their clear state.

Anti-Reflective (AR) coating improves the transmittance of light, reduces reflection from lenses, and eliminates stray lights. It is highly recommended for a clear night time vision.
