Here are some tips to reduce strain.

1) Make sure you're monitor has a high refresh rate, 60Hz is the legal requirment in offices but it should be set higher than this, mine is 85hz.

2) Make sure you have good background light, using a monitor in the dark will cause more strain.

3) Take breaks from the screen every so often to reduce strain.

nothing that serious. can cause you to become short sighted if your prone to it. Also can dry out your eyes as you don't blink as much when you look at a computer screen. My Optition said long ours of computer use and contact lenese are not really a good combination.

I agree 60Hz is really nasty, i could never use a refresh rate as low as that. Right now im running on 100Hz

A screen filter can often be useful if you have a desktop. Takes away most of the eye strain.

do u think your needing of glasses is down to using computers? I think mine would probably be significantly better if i wasn't on the computer so much.

right click on desktop - display properties - settings - advanced - monitor then look at the bit which says 'screen refresh rate'

Do what iiikewldude said.

The refresh rate is the monitor updating itself. As the what you're doing on the computer is changing all the time the input singal on the monitor must be refreshed so the image displayed on the tube is up to date.

The refresh rate is how many times per second this image changes. So if it was set a 60hz it would change 60 times per secound. The human eye can just about see this flicker especialy from a distance.

The higher the frefresh rate the lower the flicker hence better for the eyes. In the old days every time a camera was on a monitor you could see the ficker and it was quite scary.

it means your monitor won't take more than 75Hz without freaking out. The refresh rate is the rate at which the picture is redrawn on the screen. 75Hz is perfect - if find any increase above 75Hz doesn't make any real difference but the change from 60 to 75 is a big improvement. Does your screen seem alot smoother and less flickery to you?
