The blue light in LED lighting used in many consumer products may harm your sleep and pose a risk to your eyes, a new report warns. Specifically, there is new evidence that this type of light can disturb biological and sleep rhythms and damage the eye's retina, according to the French Agency for Food, Environmental and Occupational Health & Safety. Products with LEDs that produce blue light include the newest flashlights, car headlights and some toys, CNN reported. The maximum limit on short-term exposure to blue light should be reduced, only low-risk LED devices should be available to consumers, and the luminosity of car headlights should be reduced, the French agency recommended. It also said that eye protection provided by "anti-blue light" screens, filters and sunglasses varies, and there is no proof that those help preserve sleep rhythms, CNN reported. Source
