Prevent computer eyestrain

Sit at least 20 inches away from the screen, and place it at or slightly below your eye level.
From the 20-20-20 rule: every 20 minutes, focus on something at least 20 feet away for 20 seconds.
Post a reminder near your screen that says “ BLINK”. Research shows we blink far less often when staring at a computer and that is a major contributor to eyestrain.
