Patent attributes
A lens for sunglasses is provided which is capable of blocking light incident also from the side, of sufficiently fitting the face of a wearer, and of being attached to any eyeglass frame. The polarizing lens for sunglasses is formed by subjecting a laminated plate having a laterally elongated shape to a bending process and has a curved lens surface which is convex in the front face and concave in the rear face. The curved lens surface is formed into an aspherical curved surface in which the degree of curvature along a lateral axis in the outer side with respect to the center of the lens surface is larger than those along the lateral axis in the inner side and along a vertical axis and continuously varies so as to gradually increase from the center of the lens surface toward the periphery thereof.
