(CNN)The blue light in LED lighting that is increasingly used in our homes can damage the eye's retina while disturbing our biological and sleep rhythms, a French health authority warned in a new report.

New scientific evidence confirms the "phototoxic effects" of short-term exposures to high-intensity blue light, as well as an increased risk of age-related macular degeneration after chronic exposure to lower-intensity sources, according to the French Agency for Food, Environmental and Occupational Health & Safety, known as ANSES. Age-related macular degeneration, a leading cause of vision loss among people over 50, causes damage to the macula, a small spot near the center of the retina that's needed for sharp central vision.

Yet protection from the harmful effects to the retina offered by "anti-blue light" screens, filters and sunglasses varies, and their ability to preserve sleep rhythms is not proven, ANSES also said.

Ouch. I wonder if there's a difference between the warm white and cool white versions of it's the blue that's an issue?

There's less, but warm white still has a blue spike.

I'm not a fan of LED light quality. The CRI is crap. The strobe effect from the driver is worse. There's a reason galleries, decent restaurants etc. don't light with LED, or CFL for that matter. Probably not a coincidence the study came out of France...
