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 that help preserve sleep rhythms, CNN reported. The finding could help understand as to why kids find it difficult to fall asleep.

    Yes, I too have read this somewhere that the The blue light of LED can lead to irreversible loss of retinal cells and diminished sharpness of vision. Children and adolescents are particularly susceptible to such disruptions because the crystalline lens in their eyes are not fully formed. However, scientists found that LED mobile phones, tablets and laptop screens do not pose a risk of eye damage because their luminosity is very low compared to other types of lighting.
