Problems solved by technology

This process is relatively simple, but the quality of the lens is not easy to control
[0007] Film-type discoloration, the very thin layer of the top film of the lens is the discoloration factor. In this case, the lens produced in this case has a good depth of discoloration, a faster discoloration speed, and better discoloration uniformity, but the process is relatively mixed. It's more complicated, and the color change durability of the film layer is not very good

Abstract

The invention discloses a color-changing resin spectacle lens and a preparation method thereof. A hardening layer and a vacuum coating color-changing layer are sequentially arranged on the front surface of a resin lens substrate. The vacuum coating color-changing layer sequentially comprises a first isolation layer, second to sixth organic color-changing layers and seventh to thirteenth anti-reflection coating layers from inside to outside. The second to sixth organic color-changing layers are sequentially composed of a benzopyran color-changing layer with the thickness of 130-150 nm, a fulgide color-changing layer with the thickness of 65-80 nm, a benzopyran color-changing layer with the thickness of 100-120 nm, a fulgide color-changing layer with the thickness of 80-95 nm and a benzopyran color-changing layer with the thickness of 180-200 nm from inside to outside. The method is completed by flash evaporation and vacuum spraying.

Description

technical field [0001] The invention belongs to the technical field of lenses, and in particular relates to a color-changing resin spectacle lens and a preparation method thereof. Background technique [0002] The resin lens matrix can achieve the surface hardness similar to that of glass lenses by hardening the surface. The surface can withstand repeated scrubbing, and at the same time can improve the impact resistance of the lens surface to a certain extent; the formation of a perfect hardened lens requires an absolutely dust-free environment, ultrasonic Washing machine, indoor positive pressure and other conditions to ensure that the lens is not polluted by the environment and air during the hardening process, otherwise any tiny particles in the solution and air can affect the quality of the lens. After a series of cleaning procedures, the resin lens substrate enters the oven for drying, and then enters the hardening solution for hardening. After drying, it is inspected. ...
