As visible light, blue light carries energy second only to ultraviolet light, and long-term blue light irradiation will harm eye health. Blue light is blue light with a wavelength between 380 and 500 nanometers, also called "high-energy visible light" (HEV), which is the most powerful spectral segment of visible light. The wavelength of blue light is relatively short, which can directly penetrate the crystal and switch to the low blue light mode on the retina to protect the eyes.
Short-wave blue light is light with relatively high energy with a wavelength between 400 nm and 480 nm. Blue light in this wavelength range will increase the amount of macular toxin in the eyes and seriously threaten our fundus health. At present, the effective solution to blinding eye diseases caused by blue light is to film the TV.
