Make sure you take regular breaks.

I can only assume that your loss of focus is you turning on your auto-pilot.
Maybe taking some mental notes during your match could help, even if its just focused on your own improvement rather than really helping your team - how did you die in the previous round and how could you improve on that this time? Things like that.
So instead of just going through the motions per round, you set small little goals that keep you a bit occupied or make things interesting.
One thing you maybe could try is when the round is over and you are waiting for the next one to start, you quickly buy stuff, and then look away from the monitor for a few seconds and then back. It could possible be eye fatigue and focusing on something else for a short bit can often help.
Ah yeah that can definitely be a factor. Looking away from the monitor every once in a while, even for a minute, can reduce some strain of the eyes. Cannot say if it helps with the inflammation in anyway, but who knows.
Ouch. Hope it is resolved for you quickly.
