Abstract
The present invention relates to dichromic mirrored patterns on fashion eyewear that exhibits variable opacity on the exterior of a photochromic lens in response to changing lighting conditions wherein the pattern can go from virtually transparent to opaque. The dichromic mirror pattern(s) can be coated in multi-color pattern sections and can be coated so that some pattern sections have variable opacity and other pattern sections have a fixed high opacity. The effect can also be produced on an optical film to be applied to many optical surfaces.
