A UV/visible light meter which measures the average percentage of ultraviolet rays and visible light transmitted through an optical lens. It’s capability extends over the ultraviolet spectrum from 320 to 400 nanometers (nm), and over the visible spectrum from 400 to 700 nm. Light transmission through lenses can be checked without removing lenses from the frame. The meter is also useful in demonstrating photochromic lenses.
