What is blue light?
Blue light is a short-wave high-energy light having a wavelength between 400 nm and 480 nm.
The blue light in this wavelength will increase the amount of toxin in the macular area of the eye, which seriously threatens the health of our fundus.
Blu-ray-induced blind eye disease, the current effective solution is to film screens or lenses.
The anti-blue film technology is very mature and low in cost, which can effectively prevent blue light from penetrating.

3) The blue light cause sleep disorder
4) Causing glare
5) Since short-wavelength light has a relatively high energy, the incidence of fine particles in the air is high, which is the main cause of glare.
6) Visual fatigue
7) The blurring of vision.
8) Blu-ray is the main cause of digital visual fatigue (DEF).
