A system for facilitating a consumer's selection of customized color-changing lenses for eyewear, or windows, captures a digital color image of at least the face of the consumer and displays that color image to the consumer on a video display while superimposing a pair of lenses over the eyes. The display simulates the color of the superimposed lenses when made of a selected photochromic or thermochromic material. The color of the superimposed lenses is changeable, in response to consumer-controlled inputs, over a range between (a) an initial color for the lenses when subjected to at least one of (i) a first predetermined temperature and (ii) a first predetermined light condition, and (b) a final color for said lenses when subjected to at least one of (i) a second predetermined temperature higher than said first predetermined temperature and (ii) a second predetermined light condition brighter than said first predetermined light condition.

System for facilitating selection of color changing eyewear lenses and windows

An optical power-limiting passive (self-adaptive) device and method for limiting optical power transmission in lenses and windows, using layers of different photochromic compositions that exploit the full solar ultraviolet (UV) and short visible light spectrum. While a typical single photochromic material is activated by a UV band of wavelengths, e.g. 340 to 380 nm, adding a layer of photochromic material that is activated by an additional band of wavelengths, e.g., 380 to 420 nm, allows the efficient use of a wider band of solar UV and short visible light, e.g., 340 to 420 nm, thus enhancing the photochromic response to solar light.
