Has the 20-20-20 rule actually been scientifically verified as the optimal regime for relieving eye strain or was it something thought up by some bloke off the top of his head?

I wasn't able to find any conclusive evidence, but there are studies that have shown that taking breaks and changing the distance of what you're focusing on (things that the 20-20-20 rule suggests to do) can help improve eye strain.
