Avoiding Computer Eyestrain, any suggestions?

Hey, did any of you guys ever suffered from eyestrain caused by computers?

as time passes I find it more and more stressful for my eyes to read text displayed on computers, which of course hinders my work... I think it could be related (not exclusively though) to text size being too small, so I'm trying to enlarge text in most webpages, which is sometimes also a PITA as i have to start scrolling horizontally.
in that context, I don't know why higher resolutions are considered to be a "good" thing when someone is buying a pc/monitor, as they make text even smaller..?

I work mostly with a laptop, not sure if connecting it to a bigger monitor would help, as i've tried connecting it to a 42" plasma TV, and my eyes felt even worse.

I was wondering if someone had similar experience and can describe what did they do to overcome it...? maybe I have to look for a monitor with certain specifications..?

take one finger/pen and concentrate on it . Then move it away from you slowly ,then bring it towards your nose. Keep repeating this for a few minutes every hour or a two.

Use workrave - tells you to take a break every 20/40/60. You can choose.

Best of all it is free!

You may want to take a look at a thread a posted a while ago as valuable information can be found there.

First of all, download Workrave and F.lux.
It is very important to take breaks often and have your monitor's brightness turned all the way down.

Keep a wet strip of cloth on your eyes once in 4-5 hours for 5 mins.
It really helps

Install flux

Take regular breaks

Seriously.

I didn't like Flux and just decided to get Gunnar glasses. My eyes never get tired anymore but I still look away from the computer, out of my window into the distance to relax the eyes even more.

Not trying to spam here as I am new, but I just started a website that deals with this exact product. F.lux works well also. My glasses are like Gunnars but 1/2 the price.
