EyeDefender - Avoid Eystrain
EyeDefender is a freeware rest reminder designed to prevent Computer Vision Syndrome (CVS) resulting from working on a computer for hours. CVS symptoms include eyestrain, blurred vision, delayed focusing, headaches, back and neck aches, dry and burning eyes, light sensitivity, distorted color vision, forehead heaviness, and sore eyes.
CVS is impossible to get rid of but you can reduce and even eliminate most of its symptoms. The recommendation is simple – take a short rest break from your computer every hour. The difficulty lies in scheduling a regular break and keeping to it. That’s where EyeDefender can help you. It’ll remind you to take a break and relax eyes at fixed intervals.
EyeDefender sits in the system tray and displays the time left until the next break. When the time for a break comes, the program does one of the following:
- Displays a predefined picture;
- Runs the visual training to relax the eyes;
- Runs a default screensaver;
- Displays a popup timed reminder in the system tray.
