Patent ID: 8703296

Claim:
A functioning optical lens comprising: a molded polyamide layer; a first polyamide sheet layer, a second polyamide sheet layer, and an optical film layer, arranged between the polyamide sheet layers; wherein the polyamides in both of the polyamide sheet layers and the molded polyamide layer are alicyclic polyamides, wherein the first polyamide sheet layer comprises a stretched polyamide sheet, and said stretched polyamide sheet has an uniaxially stretching ratio of 1.1 to 3.5; wherein the second polyamide sheet layer comprises a stretched polyamide sheet having a uniaxially stretching ratio of 1.1 to 3.5; wherein one surface of said first polyamide sheet layer is directly fused with said molded polyamide layer without the interposition of an adhesive layer; wherein said optical film layer is directly bonded to said first polyamide sheet layer by an adhesive; wherein said optical film layer is directly bonded to said second polyamide sheet layer by an adhesive; and wherein said optical film layer consists of a film selected from the group consisting of: (1) an antiglare film including a base film of an optically transparent thermoplastic resin, and an antiglare layer having a convex-concave structure formed by spraying of fine particles, embossing, or transferring; (2) a dimming film molded by kneading optically transparent thermoplastic resins with a dimming material selected from inorganic substances and organic substances as a material for absorbing light at a specific wavelength; and (3) a polarizing film prepared by doping an uniaxially or biaxially stretched film with iodine or dichromatic dyes wherein the material for the stretched film is selected from the group consisting of poly(vinyl alcohol)s (PVAs), poly(vinyl acetal)s, and poly(vmayl butyral)s.
