Bluelight filter (to protect eye health) description

[What is Blue Light?]
Blue light is a blue light source with strong energy in the middle of the visible light.
Even with the same electronic device, the blue light from smartphones is twice as harmful as a laptop monitor and five times as much as a television.

[Why do I need a blue light filter?]
Continuous exposure to harmful light without the use of a blue light charger filter increases the likelihood of a variety of eye diseases (dry eye syndrome, poor visual acuity). In particular, if exposed before sleeping, the brain recognizes the current time as daytime, and it can adversely affect other than eye health such as insomnia.
