Abstract
A functioning optical lens includes a molded polyamide layer, and an optical sheet including a polyamide sheet layer and an optical film layer. Such a functioning optical lens may be prepared by bending an optical sheet including an optical film layer and a polyamide sheet layer, and injection molding a polyamide composition onto the bent polyamide sheet layer so as to thermally fuse the polyamide composition and the polyamide sheet layer with each other.
