Self-tinting lenses adapt automatically to any light situation and that way make comfortable and glare-free vision possible at any time.
Photochromic lenses are clear
indoors and darken when
exposed to UV light
– which means you don't have
to switch between everyday
glasses and sunglasses.
Trillions of photochromic molecules quickly change colour, size and structure when exposed to UV light or temperature increases causing the lenses to darken.
They’re clear indoors and darken outdoors. Some photochromic lenses also react to visible light and darken even when you sit in bright sunlight behind a window. They are usually available in brown, grey and grey-green.
