French health authorities say LED lights can cause permanent damage to the retina and disrupt our natural sleep rhythm, the Daily Mail reported. So be careful when using it in the future! The French agency for food, environment and occupational health and safety (ANSES) warned that strong LED lights can cause 'light poisoning'.
In a 400 page report, the agency warned that led lights could cause irreversible damage to retinal cells and eventually lead to blindness. ANSES urged officials to revise the maximum burst limit for LED lights to reduce the number of 'Blue' lights in them.
Studies have shown that led cell phones, tablet computers and laptop screens do not cause damage to our eyes, but the intense light used in car headlamps can damage our eyes. The report distinguishes between acute exposure to high-intensity LED lights and 'chronic exposure' to low-intensity light sources. The agency said that although the risk is low, long-term exposure to such light sources can also accelerate the aging of retinal tissue and lead to decreased vision.
LED products are durable, energy-saving and low-cost. In the past decade, they have occupied more than half of the lighting market. Industry experts predict that the market share of the product will continue to expand and will exceed 60% by the end of next year.
The energy consumption of LED light is about one fifth of that of incandescent light bulb, which has been widely used in home, street, office and industrial lighting. They are also increasingly used in car headlights, flashlights and some toys. Led phones, tablets and laptop screens won't cause damage to the eyes, said eye doctor Francine & middot; Bihar & middot; Cohen. He explained that because of their very low brightness compared to other types of lighting. However, these backlight devices, especially when used at night or in dark environment, may interfere with the biological clock, thus affecting the sleep state.
Al-attiya, a researcher and project manager at ANSES, points out that they will not only interfere with the natural rhythm of the body, but also increase our metabolic disorders and increase the incidence rate of diabetes, cardiovascular diseases and certain cancers, "said Al-attiya. ANSES points out that children are more vulnerable to this interference. In addition, stroboscopic phenomena in some LED lights may cause headaches, visual fatigue and other unexpected risks due to small fluctuations in current, the report said.
For home lighting, ANSES recommends buying 'warm white' LED lighting. In addition, it is also best for children to avoid exposure to high concentration of blue LED light source, and try to reduce the use of LED screen before going to bed. ANSES added that manufacturers should limit the luminous intensity of car headlights, 'they are really too bright sometimes. '
