That's good that you were able to do that and now you
don't need glasses.
I do have to wear glasses and when I was younger I didn't
know there were exercises you could do to strengthen your
eye sight.

This is precisely the exercise I was encouraged to do when I
started complaining about difficulty focusing on the distance chalk/display boards at university. It contributed to my not
having to wear glasses all my life.
