Description

Intro

Blue light accounted for about 1/3 in visible light which is part of the short wavelength. It has some characteristics such as shorter wavelength and strong energy. Also, it will cause eye macular of chronic injury under the exposure of blue light；According to the wave length of blue light, it will make the loose color phenomenon and feel dizzy when it directly exposure to the eyes. With the advancement of technology, LED is widely used in 3C products including the LCD TVs, computer monitors, smart phones and tablet PCs. LED contains more ultraviolet rays and blue light which may hurt the eyes for using it for a long time. In the past, the maculopathy mostly occurs in order people, but currently they are getting younger and younger. Therefore, anti-blue light has become the important issue for 3C industry and all kind of lens industry.
The principle of anti-blue light is to block the transmission of blue light, andGO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC Group) produced Goyenchem-BL430 High Effective Blue Light Absorbent for specifically each industry which demands for anti-blue light.
Goyenchem BL-430 can block off high energy short wave blue light 380nm~420nm, and it can be added to the anti-blue light goggles, glasses, sunglasses and other kinds of 3C industry. And it also uses to the anti-blue light film, paint, ink, PMMA, PET, PC sheet extrusion, electronic, optical and other applications by well-known manufacturers.

Recommendation

The recommendation of Goyenchem-BL430 is suggested to 0.5~5% by GYC technical department.

The addition of film thickness is proportional to the blue light absorption rate. The addition can be adjusted by customer’s formula condition and film thickness. 

Condition Suggestion
Film thickness 250μm 0.5%-1%
Film thickness under 50μm 2%-5%
General plastic material and lens thickness 1.5-2mm 0.5%-0.8%
