Spanish researchers have recently discovered that LED lights can irritate and damage retinal cells in the eye, increasing the risk of blindness. The retina is made up of many photoreceptors that are responsible for detecting light sources and converting them into images so that people can see things.
The light emitted by the LED lamp is a short-wave high-energy light source, which is blue light and violet light in the visible light spectrum. If it is exposed to such light for a long time, it may damage the retina. Researchers at the University of Madrid in Spain conducted in vitro cell tests, which showed that LED radiation may damage human retinal pigment epithelial cells. People try not to look directly at the light source, otherwise the eyes may be hurt.
