Optical lens

Abstract

The invention discloses an optical lens, which comprises a base layer, an optical layer, a color-changing layer, an anti-blue light layer and a cleaning layer arranged sequentially from bottom to top, and the optical layer includes a multilayer optical layer titanium oxide layer and an optical layer silicon oxide layer alternately The superposition composition, wherein, the bottom layer of the optical layer is the titanium oxide layer of the optical layer, and is in contact with the upper surface of the base layer, and the uppermost layer of the optical layer is the silicon oxide layer of the optical layer, which is in contact with the lower surface of the color-changing layer; The anti-blue light layer includes two upper and lower anti-blue light layers of silicon oxide layers and an anti-blue light layer titanium pentoxide layer sandwiched between the upper and lower two layers of anti-blue light layer silicon oxide layers; the present invention adopts alternate optical layers of titanium oxide layers and optical layers The silicon oxide layer greatly improves the light transmission performance of the optical lens, the anti-blue light layer can filter more than 80% of blue light, which can protect the eyes, the color-changing layer can effectively absorb ultraviolet rays and resist radiation, and the cleaning layer keeps the surface of the optical lens for a long time clean.

Description

technical field [0001] The invention belongs to the technical field of optical lenses, in particular to an optical lens. Background technique [0002] In daily life, more and more people need to wear optical lenses, whether it is to solve eye diseases, to protect eyes, or to look beautiful, etc. The surface of the lens is easy to be stained and dirty, and the optical The light transmission performance of the lens also needs to be further improved to improve the cleaning degree and light transmission performance after wearing the eyes. [0003] In addition, blue light, ultraviolet rays, radiation, etc. are very harmful to the eyes, so there is a need for an optical lens that can filter out blue light and ultraviolet rays and keep the lens surface clean for a long time. Contents of the invention [0004] The invention provides an optical lens to solve the problems of insufficient light transmission performance of the optical lens and easy dirty surface of the optical lens i...
