Eye strain from playing online chess How do you avoid eye strain while playing online chess? I wear glasses that filters UV light, take a 5-minute break every hour, play on a large screen monitor (23 inch with a refresh rate of 60 Hz), and use lubricant eye drops twice a day. But I also believe that one of the big factor is that I don't blink enough while playing chess. My eyes are most of the time wide open, in order to avoid blundering. I would really appreciate your feedback, advice, and experiences to avoid such kind of problems.
Using Eye Drops (fake tears) can be useful when exceeding recommended screen time.
What also helps me is taking frequent breaks every hour and drinking plenty of water.
