I do, however, spend quite some time behind the screen of my laptop as I am a programmer/
gamer. I tend to live by the 20 20 20 rule*, and take half hour breaks every 2-3 hours of screentime.
I honestly have no idea what it could be. I could find a condition called 'Nystagmus', but I feel it doesn't fully fit the profile of what I experience.
Thanks in advance.

*Every 20 minutes of screentime, look at something at least 20 metres away for 20 seconds.
