Optical lens capable of preventing light pollution

Abstract

The utility model discloses an optical lens capable of preventing light pollution, which relates to the technical field of lenses and comprises a lens body and a frosted lens arranged on the outer surface of the edge of the lens body. Disassembly mechanism lenses are arranged at the joints of the glasses frame lenses and the lenses of the lens bodies. Compared with an existing common optical lens capable of preventing light pollution, the frosted lens at the edge of the lens body can well shield an external light source, light rays are prevented from entering the edge to affect normal penetrating light rays of the optical lens, and when the optical lens is worn, the nose pad can generate force towards the lens body, so that the light pollution is prevented. The lenses can be conveniently dismounted and mounted through the dismounting mechanism, and if the elastic effect of the elastic film lenses or the nose pad is gradually increased along with time and the performance is poor, the elastic film lenses can be dismounted and dismounted, and the elastic film lenses can be replaced.
