Protect Your Eyes
from Your Computer
You use your eyes perhaps, more than any other part of your body. You depend on them for nearly everything you do. Are you treating them with the care they deserve? If you use a computer several hours a day, there’s a good chance you aren’t.
Eyestrain can cause eye fatigue, red eyes, pain in or around the eyes, blurred vision, stress headaches, cluster headaches, migraines, and occasionally even double vision. Eye fatigue, in turn, can cause degraded vision, and can last as long as you regularly strain your eyes.
The first step in reducing eyestrain from your computer is understanding why reading from a monitor is worse than reading from paper.
Printed text has a very "hard" edge between the black ink of the text and white paper on which it’s printed. Text on monitors has a less defined edge, and this causes "focus confusion". Have you ever seen someone wearing a shirt with funny writing that you couldn’t quite focus on? Your eyes focus in and out, closer and further, trying to find the distance at which the text should be perceived. Your eyes are literally confused, and this causes eye strain. My head hurts just thinking about it.
