My eyesight has improve to the point that i hardly ever need reading glasses. My long distant sight had always been good. I notice an improvement about 6 months ago when my readers went from 250 to 100. Now I rarely need my readers any more. My right eye sees better close up and my left sees better long distance. The combination works good for me.
My ex boss had worn glasses for 40 years and his eyesight improved to the point he no longer needed to wear them. He was 72.
