Take eye breaks

Spending long periods looking at a computer, phone, or tablet screen can strain the eyes. Throughout the day, give your eyes a break by looking away from your monitor. Try the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds.

Take eye breaks at least once every 20 minutes if the task at hand demands visual concentration, such as reading or staring at a computer screen. Your eyes may become dry, worn out, or irritated if you keep your focus on one spot for an extended period of time. Try closing your eyes for a few minutes to rest your eyes. Alternately, blink quickly for a few seconds to help in spreading the surface of your eye's natural tears evenly. To avoid back and neck aches, someone who spends the day sitting down should periodically get up and move around.
