The OD in his office - has gone "intellectually blind", towards fundamental science.
We all want an OD to "help us", with plus prevention! Right? So you ask, is prevention possible, when I can still read the 20/40 line. Typically, you will get a "hidden insult", like, "who the hell have you been talking to"? Or, there is no science that supports prevention with a plus at 20/40. Or, we have been TAUGHT to give you a strong minus 3, for 20/40. Why would you ever want anything else?
Then - they do not even help their own children - as this video reviews that issue:https://www.youtube.com/watch?v=QIGtGUVxJDE
I always appreciate a sincerely, honest conversation about this issue. You will never get that discussion and this video explains why you will no get - what you would expect.
This is why I suggest that self-verification (always pass the 20/30 line), is critical for your success. Do not ask an OD for any checking - he does not even help his own child - why would he be interested in helping YOU ??
