Blue ray exists everywhere today
As the widespread use of smartphones, tablet devices and computers increases the time we face a screen, more and more people suffer from eyestrain symptoms. One cause of this is believed to be the blue light emitted from the display on such devices.

Blue ray will cause diffusion and flickering in the vision
The shorter the wavelength, the stronger energy a light wave has, and this may cause eye fatigue. Blue light, which is next to ultraviolet light on the electromagnetic spectrum, has a shorter wavelength than other visible light. It also tends to be diffused and is believed to cause flickering in the vision.

Anti-blue ray lenses can effectively reduce incoming blue light to the eyes
Fo mo lo o's anti-blue ray lenses adopted AR coating technology. Taking advantage of the principles of AR coating in the opposite way, Fomolooo's lenses prevents blue light from passing through the lens by increasing the reflection of blue light.
