New year’s gift, for the health of your eyes!

With more and more hours spent working on a computer, we know your eyes have taken a toll. But did you know that a 20-20-20 exercise (take a break every 20 minutes and focus your eyes on an object 20 feet away for 20 seconds) can do wonders towards preserving your eyesight and relieve your tired and sore eyeballs?

The relief effect is immediate and obvious. To experience the feeling, please try our introductory-level app iRestFREE which was released years ago.

Computer vision syndrome (CVS), which this app works to combat, is "a condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time. Some symptoms of CVS include headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, polyopia, and difficulty refocusing the eyes. These symptoms can be further -aggravated by improper lighting conditions (i.e. glare or bright overhead lighting) or air moving past the eyes (e.g. overhead vents, direct air from a fan)."  - Wikipedia

"Computer Vision Syndrome (CVS) is the complex of eye and vision problems related to near work which are experienced during or related to computer use. CVS is characterized by visual symptoms that result from interaction with a computer display or its environment. In most cases, symptoms occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform the task. " - American Optometric Association
