Guys, diopters correct for what, Myopia or astigmatism?
I never had to wear any glasses, as my eyesight is perfect. And a small myopia of around .75 when I was younger seems to auto correct now that I am older (must be .90-.95 now). However I noticed that playing with diopters on my binoculars, nothing happened. Maybe it's astigmatism they correct?
Edit: I just made a mistake: myopia I meant on my right eye. My left one was always bionic 10/10
