SPARTANBURG, S.C. (WSPA) – There’s a new phenomenon that links your cell phone to temporary blindness.

It’s called “Dark Adaption.”

The New England Journal of Medicine cites a few examples of people looking at their cell phone at night and experiencing blindness that can last up to 15 minutes.

They say the cause may be something as simple as reading in the dark with just one eye.

This happens sometimes, they say, when you are lying on your side.

The cell phone light stops the other eye from adjusting to the dark, and you’re left temporarily blind.

Optometrist Dr. Albert Pang says “It’s kind of like freaky because of the fact that it’s going to scare you because suddenly one eye can see, one eye cannot see. It just freaks you out, but again when you talk about is there going to cause any permanent damage, not any more than reading a tablet or reading your phone in the dark.”

The doctor says if you don’t have enough Vitamin A or Beta Karotine, your eyes will take longer to adjust to the dark.Find 8News on Twitter, Facebook, and Instagram; send your news tips to
