Blue light blues: Your devices could be blinding you

Uh oh. A new study has some scary implications for our reliance on cellphones, tablets and computer screens. Those blue-tinged displays could lead to serious eye problems – maybe even blindness.

Findings published in Scientific Reports show that blue light may cause or accelerate macular degeneration, the leading cause of vision loss in the U.S. The condition can occur as we age, but exposure to specific light has been shown to irreversibly damage certain cells in our eyes.

To stave off damage, many devices have settings for “warm” light, or you may want to limit your nighttime screen exposure.
