Is there any software to keep eyes distracted from monitor [closed]

I have a 19 inch LCD monitor but my eyes are hurting when sitting too much in front of the PC so I used an eye protector software, but it irritates me since it is a trial version, so I cannot edit its settings, so it just pops up accordingly to its predefined time.

Can any one suggest me a good software. This is the site of that software http://www.eyeprotectorpro.com/

workrave is an RSI (repetative strain injury) app that interrupts you periodically to rest your eyes, hands, and stretch. The timers are configurable for your needs, and it supports networking (in the event that you use multiple computers). I Highly recommend it.

Workrave is free.

EDIT: Available for Windows/Linux

I know how irritating it can be to have your eyes strained by a monitor. Whenever I've had to change jobs/offices I noticed my eyes would start to hurt within a few hours of sitting at the PC. Adjusting both the brightness and contrast always solved that problem.

A little while ago, the lighting above the area where I work dimmed for whatever reason, and I noticed my eyes began to hurt once more. This proved to me that its not just the monitor display settings, which had not changed, but the lighting of the rest of the environment that made the difference. Again, even in this case, adjusting both the brightness and contrast on the PC display relieved the strain on my eyes.

Current Display Settings

desktop

Standard lighting: Brightness 60, contrast 65

Low lighting: Brightness 65, contrast 55

CURRENT: Brightness 50, contrast 50

laptop

low (current) lighting: Brightness 45, contrast 35

Really Low lighting: Brightness 0, contrast 0

If I were to forget what they were or they were reset by accident, I would do:

1. check for sense of subtle strain on the eyes while sitting in front of PC
2. adjust brightness or contrast down until I got a noticeable improvement in eye strain
3. if I don't like the screen display color quality, increase either one of brightness/contrast while ensuring my eyes are not affected.
4. keep going back to #1 until I feel no strain on my eyes at all

I think the key is that my eyes are sensitive enough that I don't need to sit in front of a PC for hours before knowing whether the settings are right for me or not. I know immediately. On the other hand, it might be much harder to find the right settings after my eyes have been straining for a very long time.

All you want is to protect your eyes from the computer screen. Thus, try these tips as below:

Monitor Location Ideally more than 25 inches from eye and 6 inches below the horizontal eye level. Anti-glare screen Will decrease the amount of light reflected from the screen.

Light effect Use suspended lights from ceiling and windows with shades, blinds or curtains. Avoid light hitting directly on eyes.

Sitting posture Use chairs with armrests which are able to provide, support while typing, position of head slightly tilted downwards and height of the chair adjusted appropriately so that the feet reset flat on floor.

20-20-20 rule Follow the 20-20-20 rule, which means every 20 minutes, look away from the monitor, and focus on an object at least 20 feet away, for 20 seconds.

Eye Exercise Choose your eyes and slowly roll your eyeballs clockwise and anticlockwise. Repeat it 3 times.

Blinking Blink frequently to keep the front surface of your eye moist.

Computer Eyewear To block the blue light, glare, and radiation when in computer and mobile device use. It works better than a monitor or screen protector.
