Subject: I believe in searching for scientific truth.
Regarding: I expect sincere answers - not insults - when I ask about the proven effect of a minus on the eye.
Here is a video by an optometrist - arguing for prevention.
I truly "gave up" on ODs a long time ago. I know the minus "works" and is impressive. But it is (in a deeper scientific sense - destructive).
You can't go to an OD for "help" - because he will tell you that you are 1) Stupid, 2) Don't "understand science", 3) If you wish prevention - then do it yourself.
But, don't believe me, read what they have to say.
