What is Blu-ray?
Natural light is sunlight, which has seven colors: red, orange, yellow, green, blue, and purple. Blue light is the blue light inside, and the fluctuation range is between 385nm-505nm.
Blu-ray has pros and cons:
Advantages: 445~505nm long-wave blue light reaches the optic nerve through the eye retina, helping sleep and soothing emotions.
Harmful: 415~445nm short-wave blue light affects the eyes and sleep quality.
Remarks: In the range of 415~445nm, the light transmittance is less than 80%, and above 445nm it is greater than 80%. In this range, it is healthy.
Where does blue light exist: as long as there is light, and artificial blue light, such as in front of the screen, mobile phone and computer screen.
So this is why friends who often watch mobile phones, TVs, and computers need to wear anti-blue light glasses.
