CVS

July 21, 2014

Using a computer for long periods of time may cause negative effects such as headaches, blurred vision, eye strain, dry eyes, irritated eyes, polyopia (multiple vision), and difficulty refocusing the eyes but NOT cancer. The negative effects are symptoms of Computer Vision Syndrome (CVS).

I remember my mom telling me a technique to avert these bad effects, something about looking at trees outside or far objects for at least 20 seconds to relax the eyes. For people who want to prevent or lessen the symptoms, such as me (a heavy computer user), the rule my mom was talking about was the 20-20-20 RULE. 20 Minutes, 20 Feet, 20 seconds. What. What is it, you might ask. 

For all you heavy computer uses.
