The high-energy blue light of the mobile phone is 500 nm. According to the researchers, the human eye is more sensitive to short blue light. If you stare at a mobile phone or computer screen for a long time, the blinking frequency will be reduced, resulting in dry eyes, astringent eyes and sore eyes. Gradually, myopia will occur.
This kind of high radiation energy blue light will directly pass through the cornea and lens and contact with the retina, and produce free radicals on the retina. When the free radicals in the human body exceed a certain amount and lose control, this kind of free radicals will bring harm to our health, accelerate the cell oxidation in the macular area of the retina, turbidity of the crystal, aggravate color difference and visual blur, and cause severe fatigue In the form, it slowly engulfs people’s eyes, causing permanent damage to the eyes.
