Problems solved by technology

[0004] The inventors of the present application have found in the long-term research process that most of the blue light filtering devices currently on the market block blue light by adding substances with blue light filtering properties to the base material of the device. As a result, the substance with the ability to filter blue light falls off, thereby reducing the ability of the device to block blue light

Abstract

The present application discloses a device for filtering blue light and a preparation method thereof. The device is obtained by copolymerization of a base material and at least one compound having the property of filtering blue light; wherein, the compound having the property of filtering blue light has the following general formula : Wherein, R1 is R2 is hydroxyl or R3 is hydrogen or methyl; R4 is hydrogen or methoxy; R5 is hydrogen or methoxy. Through the above method, the present application can improve the stability of the device for filtering blue light.

Description

technical field [0001] The present application relates to the technical field of optical equipment, in particular to a device and a preparation method for filtering blue light. Background technique [0002] With the advancement of science and technology, many electronic products that emit near-ultraviolet blue light have been developed in recent years, such as liquid crystal displays and mobile phone screens. The blue light in this band has extremely high energy, which can penetrate the lens of the user's eye and reach the retina directly. If the user uses such electronic products for a long time, it will cause macular degeneration in the retina, which will cause irreversible damage to the user's vision. [0003] In order to reduce or avoid the damage caused by blue light, there are many blue light filtering devices on the market, for example, screen protectors and glasses with blue light filtering. [0004] The inventors of the present application have found in the long-t...
