Light Adjusting
What are Photochromic or Light Adjusting Lenses? They appear like regular clear lenses when worn indoors but automatically adjust and darken when you move to a brighter area. The light-sensitive molecules inside photochromic lenses change when they are exposed to Ultraviolet (UV) rays. Once UV light is removed, the process reverses and the lenses become clear again.
SmartVista offers Light Adjusting lenses. After you select the frame style during the purchasing process, please select one of the Photochromic colors to enhance your eyeware. Available in your glasses with or without prescription.
