The blue light from your LED screen isn’t hurting your eyes

Last week, several articles warned of a new report from a French government agency outlining dangers of blue light from LED lighting. These headlines are alarming because, depending on the time of day and your phone or computer’s settings, your eyes are being exposed to blue light right now. LEDs, or light-emitting diodes, are hugely popular—they’re more energy-efficient than traditional lights, and 90% cheaper now than they were a decade ago. All screens have LEDs that emit blue light, as do many offices and homes.  But the risks to typical screen-users eye health is seriously overstated, both by the agency’s own report and press release, and in the news headlines that followed.
