An elementary school teacher of mine had this happen to her (this was in the early '90s, so her experience I'm guessing would have been in the late '60s).

One day she wrote her name twice on the whiteboard and asked us to identify the difference between the two; visually they were identical, but she wrote one with her left hand and one with her right. She said as a kid she was made to use her right hand when she started showing signs of left-hand dominance.

I didn't know what difference it made and there was one left handed scissors so it went to the kid who knew. I'm left eyed and often wonder if I should have learned to write left handed.

wait, you just gave me an extreme epiphany about my significantly worse right eye myopia. the divergence definitely snowballed from the "use it or lose it" thing and me not wearing my glasses as much as possible

Every study in scientific examination that concept says that for myopia and such things use it or lose it does not apply. Use it or lose it does apply to some things but not that case.
