Do LED Lights Lead to Blindness?

There has been active propaganda of LED light bulbs using innovative technologies in residential and public buildings, as well as on the streets and roads. LED lighting consumes less electricity, has a lower operating temperature and a longer service life. With LED lights, you can easily adjust brightness, color or temperature using a smartphone or a special control panel in a smart home.

However, researchers from the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) concluded that the light emitted by LED lamps damages human eyes. LED lamps are phototoxic, and their light can destroy the retina and impair vision.

ANSES has divided the light radiated by LED lamps into types. According to the agency, warm light causes the eyesight the least risk of phototoxicity, while the “cold” type illumination represents the maximum harm to human eyes. LED light is emitted with high intensity. However, the ANSES study claims that low intensity light also causes harm to the eyes, which can “accelerate the aging of retinal tissue,” as well as reduce visual acuity and cause degenerative diseases such as macular degeneration.
