After that of Anses, a new study by Inserm confirms that LEDs are bad for the eyes. The lighting trade union, however, prefers to talk about misinformation.
The ANSES had launched the alert 5 years ago. As of 2010, the National Agency of Public Health Security ensured that the high proportion of blue light that characterizes the LED led to “toxic stress for the retina”. It posed a particular risk to children because “their lens remains in development and can not fulfill its role as a filter of light”. Immediately, Que Choisir launched a test on the dangerousness of LED bulbs, with an unmistakable conclusion: “flee the spots”. The latter are indeed composed of apparent diodes and their light is sent in a directive way, like a laser beam. Given their blue light content, it’s bad for the view.
Since then, research on LED bulbs has continued. The Inserm has just realized a new study with rats moving freely in an enclosure illuminated by LEDs bought in store. Its results are disturbing. The cells of the retina died one after the other. “LED light is much more toxic than neon light,” confirms Alicia Torriglia, research director at Inserm and responsible for the study. We obviously do not pretend that the human eye behaves like the eye of the rat, but it can be subjected to the oxidative stress of LED several hours a day for many years. There is fear of premature aging of the eye for younger generations who will be exposed to it for life. ”
Professionals Are Challenging
Faced with these new revelations, the lighting union has just retaliated: “Stop misinformation,” he said in a press release accusing the media of having “relayed incomplete, dramatized information And anxiogenic “on LED bulbs. To summarize, lighting professionals claim that blue light is the proper feature of all light sources, not just LEDs, and recalls that manufacturers are required to verify that their LEDs do not emit too much, in accordance with the Standard NF EN 62471.
However, LED bulbs have a specific risk due to their high proportion of blue light. As for the standard, it was not designed for LED. The risk assessment can be done at 20 cm or more than 1 meter from the eye, and the limit values are established to avoid acute retinal injury in the workplace, in no way to protect the population from the effects Linked to long-term exposures. “The evolution of standards has not kept pace with technological developments,” deplores Alicia Torriglia. The regulations are not suitable for light-emitting diodes. The oxidative stress responsible for the destruction of the cells of the retina is not detectable in the framework of the tests in force.
