Patent ID: 7784939

Claim:
A polarizing lens for sunglasses comprising a polarizing lens object formed by pasting a lens element for an object and a lens element for an eyepiece to an object plane and an eyepiece plane of a polarizing film having a polarizing axis oriented horizontally, respectively, said polarizing lens object having a spherical surface with a spherical radius and a portion extending from a first curved position of the polarizing lens object that corresponds to a peripheral portion of the eyes of a user to a terminal end of the polarizing lens object thereby forming a first rotating surface, said first rotating surface being formed of a part of a rotating surface obtained by rotating a vertical section of the spherical surface at the first curved position provided that a vertical rotating axis of said vertical section of the spherical surface passes through a radius line of a spherical radius on a plane at the first curved position as a first rotating condition and a radius of the first rotating surface is smaller than the spherical radius as a second rotating condition.
