Since a few years, I've been experiencing involuntary, rapid eyeball jerks. They happen in any direction, as if the muscles rapidly contract and retract. They last for about a tenth of a second, and I generally don't realize I had such a jerk until a few seconds after. It doesn't hurt when it happens, I do however feel a bit dizzied for a minute after. It occurs about once every 2 weeks.
I do not suffer from epilepsy. I have near-perfect eyesight, as I don't need glasses or lenses to see sharp. 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.
