So Exciting!Meet you here,Mate!

Many gamers complain about complaints such as red, burning and tearing eyes during long game nights.

Modern flat screen displays (mobile phone, PC and TV) emit a strong blue light with a high proportion of short wave 400-450nm(blue) spectral parts. It is HEVL (High energy visible light) ,Often referred to as "blue light" .
Scientific studies suggest that this light is a great burden on the eyes and can irreversibly damage them. In addition, it is known from numerous studies that blue light is particularly hormonal, which can
lead to sleep disturbances due to the suppression of melatonin production, for example. For the body, it means permanent stress.But not all blue light is bad,Blue light between 450-500nm
is making the body produce melatonin which regulates circadian rhythm(help the body's natural wake and sleep cycle),we can call it good blue light and needed for good health. It boosts
alertness, helps memory and cognitive function and elevates mood.

Prevent digital eyestrain:

Block Wavelength 400-450nm harmful blue light，Slow down the eye fatigue caused by using electronic screen for a long time. Also, too much short wavelength blue light entering the human body will cause circadian rhythm disorder.

Maintain melatonin generate:

Wavelength 450-500nm is good blue light,80% enter means good blue light can effective pass,promotes melatonin secretion and ensures good sleep and circadian rhythm.
