My eyes do get tired too at times from playing and I am forced to take breaks on many occasions. I went to the optician recently and he gave me some eye drops and I am now wearing glasses.I’ll say the maximum hours I’ll play now its 2 hours. After that eyes turn red, really itchy and they start to bother me a lot. I try to avoid it by using my lenses and keeping hydrate during my gaming but eventually I’ll need to stop and that’s going to happen in an hour or two.
hours in a row.I try to take breaks as often as I can so the longest I play without breaks is maybe 2 hours. I don't want my eyes to get dry and tired so I have to stop sometimes, blink a lot and just move them because looking at the screen for too long isn't healthy.

I play around 3 - 4 hours straight. I don't really consider it appropriate as it is recommended to rest the eyes every hour.

I don't play more than 3 hours at a time. Don't really want to put my eyes to shit any more than they are already.
