The French Agency for Food, Environmental and Occupational Health & Safety announced on May 17, 2019 that blue light emitted by LED lights would cause irreversible damage to retinal cells, leading to decreased vision, macular degeneration, and even blindness. ANSES urged officials to modify the maximum exposure limit of LED lights，
Why Blue Light Harms Our Eyes
The tissue receives light in the human eye is called the retina. After long-term direct view of the light source, the high brightness of the 400–500 nm blue light band in the light source may cause photochemical damage to the retina. The damage can be divided into two categories: damage caused by direct reaction of blue light with visual pigment in visual photoreceptor cells, and damage caused by reaction of blue light with lipofuscin in retinal pigment epithelial cells.
