After the Anses, a new study of Inserm confirms that LEDs are bad for the eyes. The Union of lighting, he, rather talk about misinformation.
Anses had launched the alert 5 years ago. As of 2010, the national safety agency assured the high proportion of blue light which characterizes the LEDs led to a “toxic stress to the retina. She was pointing to a particular risk to children from the fact that “their lens remains in development and cannot carry out its role of the light filter.” Immediately, that to choose launched a test on the dangerousness of the LED bulbs, with a conclusion without appeal: “flee the spots. These are in fact composed of apparent diodes and their light is sent in a directive way, like a laser beam. Given their content in blue light, it’s bad for the view.
Since then, research on LED bulbs continued. Inserm has just completed a new study with rats moving freely in a Chamber lit by LEDs purchased in-store. Its results are troubling. The cells of the retina died one after the other. “The LED light is much more toxic than neon, confirms Alicia Torriglia, Director of research at Inserm and responsible for the study. Of course, we do not pretend that the human eye behaves like the eye of the rat, but it may be subject to stress oxidant LED several hours a day for many years. It is feared a premature ageing of the eye for the younger generations that are to be displayed to life. »
The professional challenge
In the face of these new revelations, the Union of lighting comes to retaliate. ‘Stop the misinformation’, he says in a press release, accusing media of “relaying information incomplete, dramatized and anxiety” on LED bulbs. To summarize, lighting professionals claim that blue light is characteristic of all light sources, not only of the LED, and remind the manufacturers are required to verify that their LEDs do not emit too much, in accordance with the standard NF EN 62471.
LED bulbs yet present a specific risk associated with their high proportion of blue light. As to the standard, it was not designed for the LED. The risk assessment can be done at 20 cm or more than 1 meter of the eye, and the limit values are established to avoid acute lesions of the retina in the workplace, in no case to protect the population of exhibitions on the long term effects according to TOUGHESTFLASHLIGHTS.COM. «The evolution of the standards did not follow technological developments, laments Alicia Torriglia.» The regulation is not adapted to the light-emitting diodes. Oxidant stress responsible for the destruction of the cells in the retina is not detectable in tests in force. »
