Advantages of photographers wearing yellow lenses

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. The most effective way to solve the blinding eye disease induced by blue light is to shoot TV. Blue-light-proof membrane technology is very mature and low cost, which can effectively prevent blue light from penetrating.

It is especially pointed out here that blue light is not all harmful blue light, what is really harmful is blue light with a wavelength of 400 to 450 nanometers, while blue light with a wavelength of 480 to 500 nanometers has the function of regulating biological rhythm, which is related to sleep, mood and memory and is beneficial to human body. Moreover, whether short-wave blue light will definitely cause harm to human eyes is related to irradiation intensity and irradiation time. When the light reaches a certain level and lasts for more than two hours, it may cause damage to the retina.
