Anecdote, as a teen, I was diagnosed as having myopia (mostly on one eye) and got glasses. I refused to wear them most of the time, during that time I spent more time outdoor, looking further away and also develop an habit to stare at points far away whenever I'm thinking.

Since I'm 25, whenever I do an eye test, they tell me that I have a very small amount of myopia on one eye but it's very small and I don't need glasses.

Interestingly, when I talked to an eye doctor recently, he told me that they no longer try to push glasses so much when there's a small vision issue.
