PROBLEM TO BE SOLVED: To provide a lens used for goggle sunglasses, the lens being designed so that contact of a glasses frame and goggles or the like with lenses is prevented, the goggle sunglasses can be worn even when a user wears a pair of glasses or even if they are not worn, a field of view, particularly, the visual fields of the left and the right side sections are wide. SOLUTION: An uncut lens for the goggle sunglasses has a front section 1, the left and the right side sections 2, 2 and intermediate sections 3, 3 disposed between the front section and the face of a user. The front section 1 and side sections 2, 2 are formed along the surface of a sphere of a radius of 120 to 140 mm. The sidewise length of the front section is 120 to 150 mm. The maximum sidewise dimension between the left and the right side sections 2, 2 as viewed from the front, is 160 to 180 mm. COPYRIGHT: (C)2009,JPO&INPIT
