Hours of staring at the TV, computer screen, iPod, iPad, iX dries out and weakens your eyes (not to mention your brains). Good eye-replacement options aren’t going to be around for a long time, so try to make it a habit to look long-distance at least once every 30 minutes. Out a window into the natural light is good. Relax those close-vision muscles! Do some eye rolls! Breathe! (It’s hard to remember, so set a timer. Lots of apps for that, like 30/30.) . . . All right, I’m off to get an eye-massage.
