Spanish studies call LED light or irreversible damage to the retina

Although LED lamps are more energy-efficient than conventional bulbs, they can reduce power consumption by up to 85%, and a bulb can be used for 10 years. It is widely used in mobile phones, TV screens and lighting, but it is easy to damage if it is used for too long. vision. According to British media reports, a Spanish study confirmed that LED bulbs may cause irreparable damage to the retina and increase the risk of blindness.

Modern people spend about 6,000 hours a year squinting at things, most of which are exposed to artificial light sources. The human retina is made up of many photoreceptor cells that sense the light source and convert the light source into an image so that people can see things. The light emitted by the LED lamp is a short-wave high-energy light source, which is blue and violet in the visible light spectrum.

Researchers at the University of Madrid in Spain published an article in the journal Photochemistry and Optics that pointed out that long-term exposure to LED radiation may damage retinal pigment epithelial cells and damage the retina.

Dr. Celia Sanchez Ramos, research director, reminded that lamps such as desk lamps should not use LED bulbs as close as possible. Try not to look directly at the light source with eyes, and pay attention to the use time, close the eyes every 20~30 minutes. rest for a bit.
