Computer Vision Syndrome
Staring at the tiny font in your texts and scrolling through dozens of tweets can lead to eyestrain, blurred vision, dizziness, and dry eyes. And blurred vision plus sore neck muscles can also cause headaches.
If you're experiencing eye discomfort, make your phone's font size bigger. Mark Rosenfield, O.D., Ph.D., told Men's Health that phone users should try to hold their phones at least 16 inches away from their faces. Every few minutes look up from your screen at something far away for short breaks, and don't forget to blink.
