View page
US Patent:
20130329184, Dec 12, 2013
Filed:
Jun 8, 2012
Appl. No.:
13/492601
Inventors:
Adam Ahmad Barzak - Anaheim CA, US
Andrew John McKenzie - Long Beach CA, US
David Mark Ambler - Rancho Palos Verdes CA, US
International Classification:
G02C 7/10
G02B 1/08
G02C 7/12
US Classification:
35115956, 35115964, 35115961, 264 132
Abstract:
The present invention describes ophthalmic lens products comprising a multilayer wafer and an injection-molded polycarbonate inner portion. The multilayer wafer includes a dyed, photochromic or polarized layer between a tinted inner layer and an outer polymeric layer. The inner layer may be solid or gradient-tinted. The polycarbonate inner portion of the lens product is directly fused to the tinted inner layer of the multilayer wafer during injection molding. The invention further describes a method to produce a gradient-tinted polarized polycarbonate eyewear lens product by obtaining a multilayer wafer having an outer layer, an inner polycarbonate layer, and a polarized layer between the inner and outer layers, applying a gradient tint to the wafer's inner layer, placing the gradient tinted wafer within an injection-molding cavity, and injecting molten polycarbonate directly against the wafer's gradient-tinted layer to form the inner portion of the lens product and to fuse it to the wafer.

US Patent:
20170139230, May 18, 2017
Filed:
Nov 16, 2015
Appl. No.:
14/942873
Inventors:
- Torrance CA, US
Adam Ahmad Barzak - Anaheim CA, US
International Classification:
G02C 7/02
G02C 7/06
G02C 11/00
G02C 7/10
G02C 7/12
Abstract:
The present invention describes composite constructed ophthalmic lenses comprising at least two layers of optical materials that provide a composite structure over a practical vision zone of the lens product, are identifiably disparate from each other, and are integrally bonded to each other such that the adhesion of the first layer to the second layer exceeds a ranking of at least 3 when tested according to specified tests. In a preferred embodiment, one layer comprises thermoplastic polycarbonate and the second layer comprises polyurea-urethane material and one or more additives. The first layer may comprise a polarizer. The composite lens may also comprise coatings or other components.
