No, Blue Light From Your Smartphone Is Not Blinding You
Blue light from electronic screens is not making you blind. A recently released study has been creating both concern in the public and alarmist headlines from news outlets worldwide. But experts are cautioning that the news reports are leaping to unfounded conclusions about the potential effects of blue light on the eye.
Retinal is toxic to some cells whether or not it’s exposed to blue light. Live retina cells have proteins that can protect them from these possibly toxic effects.
Other cells that were also exposed to retinal and blue light by the investigators would not be exposed to blue light in the body. Blue light only reaches the skin and the eyes. It cannot have any effect deeper in the body.
Spending too much time looking at a screen can keep people from blinking as often as they should and from focusing on things at different locations. This can make the eyes feel dry, gritty, tired or strained. The simple solution is to look at least 20 feet away, for 20 seconds, every 20 minutes.
