Subject: Making a "transistion" to a Snellen Visual Acuity standard.
Item: Do you read the 20/30 line? (With ghosting or double vision?)
http://frauenfeldclinic.com/clear-flashes-the-prescription-to-maximize-that-stimulus/You are judged by the DMV, as reading the letters on the 20/40 line (prefer the 20/30 line).
This is objective reading, even with "ghosting". These "clear flashes", of reading the 20/30 line - are you
best objective indicator of future success.
I think this situation is profoundly tragic - but I do not blame the optometrist.
I think that by learning and respect, prevention is possible, if you have the long-term motivation to do it yourself.
No, it is not "wonderful vision", but it is indeed an indicator that you should stick with your own program.
I prefer to have my own -1 and -1/2 diopter, to check my own refractive state, but that is optional.
I truly do not "trust" any OD measurement - because they don't care.
But I "care" for my vision, because the OD does not. This means, I have a minus lens and always
CHECK MYSELF.
This might mean a "compromise" where I *see* the minus lens gives me 20/15, when I have
20/20 - but you can bet that I would not wear a minus/astigmatic lens - with self-confirmed 20/20.
I am personally tired of begin "ripped off" by this over-prescription policy. I do accept personal responsibility
for my own "negative state" inducing habits as a child. (I do not directly blame the OD.)
But I know it for what it is.
