Abstract:
1. A polarizing lens, which is formed by laminating an aromatic polycarbonate protection layer through an adhesive layer to each surface of a film having polarizing properties, curving the resultant laminate so as to form a light incidence side having the protection layer positioned thereon and to impart spherical or aspherical surfaces thereto to obtain a polarizing sheet, and injecting an aromatic polycarbonate onto a surface opposite the light incidence side of the polarizing sheet to form a sheet of the injected aromatic polycarbonate, wherein a retardation value of the protection layer positioned on the light incidence side is 2,000 nm or more and less than 20,000 nm, and wherein a stretch axis of the protection layer positioned on the light incidence side is perpendicular to an absorption axis of the film having polarizing properties, and wherein said laminated aromatic polycarbonate sheet the aromatic polycarbonate in the protection layers is prepared from 2,2-bis(4-hydroxyphenyl)propane.
