Combating Eye Stain While Playing

I've heard that those special glasses for computers work wonders. I think they block blue light and that is what causes the most eye strain. I personally haven't used them, but a lot of people swear by them.

Take a break every 30 minutes or so, and allow your eyes to look at distances farther away than just your monitor.

You can add an app for this on your computer. It will adjust the screen colors based on where the sun is positioned where you are. 

Enable auto brightness adjustment and use a timer to remind yourself to take break!

Take break regularly and vit. A source fruits. 

I have a blue light filter on my prescription glasses and I have had a noticeable reduction in eye strain, 

my friend swears by his blue light glasses

LOL why the blue text man. Either anti glue light glasses or replace the monitor that does not emit any blue light.

^ ditto on this. Since I'm wearing glasses these days anyways, I have a blue light filter coating on my persciption lenses and have noticed an improvement.

Taking breaks regularly is always helpful as was also suggested, both for eyes and body, and both Windows and Mac have built in blue light filter settings that can be used to decrease blue light based on a time of day, or there are better apps which change it more gradually throughout the day as mentioned by jose m.
