Abstract
An eyeglass lens (1) includes a polarizing part (10) and a non-polarizing part (20). The polarizing part (10) includes a base part (11) and a polarizing sheet (12). The non-polarizing part (20) is adjacent to the polarizing part (10). The polarizing sheet (12) is in face contact with the base part (11) in a non-separable manner. The non-polarizing part (20) has a thickness (W1) greater than a thickness (W2) of the base part (11). The base part (11) and the non-polarizing part (20) form a light transmitting member (2) that is a single solid member. The light transmitting member (2) is made of a colored resin.
