Abstract
A transparent multi-layer lens construction to be worn as a sunglass lens, or a fashion lens, that reflects light in a diffuse manner. The multi-layer lens construction is, in part, a combination of surface form and surface texture combined with a reflective medium and an anti-reflective coating. The present invention offers vast improvements over previously disclosed lens constructions in that it provides for both improved reflectivity and improved optical quality.
Claims60
A diffuse reflecting lens comprising:
- a first light transmitting lens element having first and second surfaces, said first surface having a major optical area, said first surface within said major optical area comprising a diffuse reflecting form texture;
- a reflective medium applied to at least a portion of said diffuse reflecting form texture, said reflective medium being sufficiently thin to reflect only a fraction of the light impinging thereon, the remainder of the impinging light passing through said reflective medium, said reflective medium applied to said diffuse reflecting form texture representing a prepared first surface of said first light transmitting lens element;
- a light transmitting adhesive layer applied to said prepared first surface, said light transmitting adhesive layer having fifth and sixth surfaces, said fifth surface of said light transmitting adhesive layer conforming to said prepared first surface of said first light transmitting lens element;
- and
- a second light transmitting lens element having third and fourth surfaces, said fourth surface of said second light transmitting lens element being in contact with said sixth surface of said light transmitting adhesive layer;
- said second surface of said first light transmitting lens element and said third surface of said second light transmitting lens element forming outer surfaces of said diffuse reflecting lens, said second surface forming a front surface and said third surface forming a back surface, said front surface having an anti-reflective coating applied thereon.
