Color changing lenses, also known as "photosensitive lenses". Silver halide is added into the glass lens, but at present, resin color-changing lenses are mainly used, chemical substances such as a pyriproxyfen and the like are added into the acrylic resin lenses, so that the originally transparent and colorless lenses can be changed into colored lenses to be protected when being irradiated by strong light, and the glass lenses are suitable for being used indoors and outdoors. The photochromic lens is made of optical glass containing silver halide microcrystals, and can quickly darken under the irradiation of sunlight and ultraviolet rays according to the principle of photochromic interconversion reversible reaction, completely absorb the ultraviolet rays, and have neutral absorption on visible light, and can quickly recover to be colorless and transparent when returning to a dark place. The existing color-changing lens on the market has poor anti-glare effect and cannot adapt to the environment with strong light. Therefore, a photochromic lens with better anti-glare effect is needed to solve the above problems.

Referring to fig. 1, fig. 1 is a schematic view of a highly effective anti-glare color-changing lens with metal dielectrics according to an embodiment of the present invention.

As shown, a metal dielectric high-efficiency anti-glare color-changing lens includes: the anti-dazzle substrate comprises a substrate body 10, wherein a color-changing coating 11 is filled in the substrate body 10, and a wavy anti-dazzle convex surface 12 is arranged above the substrate body 10; a hardened film 20 disposed over the substrate body 10, the hardened film 20 being bonded in contact with the anti-glare convex surface 12; a reflective film 30 disposed over the hardened film 20, the reflective film 30 being a chromium film; a metal dielectric film 40 disposed over the reflective film 30; and a protective film 50 disposed over the metal dielectric film 40.
