Abstract:
A spectacle lens is produced through a first step of stacking a first member colored in cyan and a second member colored in red and integrating the first member and the second member, and a subsequent second step of partially polishing a periphery of a convex surface of the first member. Provision of the polishing step enables unique design and production of appropriate numbers of widely varied distinctive spectacle lenses.
