Spectacle lenses and a pair of spectacles using the same |
摘要 |
Uncut spectacle lenses and a pair of spectacles using such lenses are provided. The uncut lenses includes a lens body and a pair of tabs fixed to an outer periphery of the lens body in opposite relationship with each other with respect to the geometrical center of the lens. The optical center of the lens is set up at a position spaced apart from the geometrical center thereof such that a line connecting the geometrical center and the optical center of the lens makes a predetermined angle with respect to a central line passing through the pair of tabs and the geometrical center of the lens. Further, the invention provides a polarizing spectacle lens wherein the optical center of the lens is located at a position spaced apart from the geometrical center and the line connecting the geometrical center and the optical center makes a predetermined angle with respect to the axis of polarization of the lens.
