Does Blue Light From Smartphones Cause Blindness?

Does blue light from smartphones cause blindness? Short answer: No. Headlines claiming that the blue light from our smartphones have been making the rounds. As is usually the case with the media when it comes to science, there’s always greater context (or it’s just downright BS).

The American Academy of Ophthalmology spelled it out recently: No, Blue Light From Your Smartphone Is Not Blinding You. That was in response to a study published this summer that found blue light, plus a chemical naturally found in certain eye cells, could damage cells. The catch: researchers did not use any actual cells from our eyes, because our eyes have defenses against exactly this sort of damage. (They were studying a question unrelated to eye health; the Verge has more on the purpose and meaning of the experiment.)
