Subject: Why must I wear a plus (when I am an 20/40 and hate wearing a plus for near)?
Re: My OD told me that a plus "will not work". Why should I take personal responsibility to IGNORE his recommendation that I NOT protect my distant vision with my own plus lens?
Here is part of my attempt to answer the question of "WHY" it would be wise to ignore destructive "standard practice", and check your Snellen yourself.
I had good eye-doctor describe much of this problem (including my bad faults as a child). But it is very difficult to describe to a mother, WHY, when the child has 20/40 and refraction of -1 diopter, the child should NOT wear that obvious minus lens, and instead 1) Sit up, and 2) For the long-term, always wear a plus, and read at the "just blur" point.
Unless the person has a good education, and the motivation to do it -- the child will simply IGNORE ALL WHO ARE ATTEMPTING TO HELP HIM.
For the person who asks, "WHY", you have provided some of the answer. I hope everyone read your description of how we ask, "WHY", and how the public always ignores the answer -- or does not answer his own question of "WHY".http://www.doyletics.com/arj/whyrvw.htm
As you might know, I "arm twisted" my nephew to use the plus, when it "...got blurry out there".
He did this in a logical and consistent answer. He is highly intelligent, wise and motivated.
How do I know he did this (under his wise control).
1) Because he never failed the DMV requirement of 20/40. and when we checked together, he read the 20/20 line
2) Because if he did not do this, he would be about -4 diopters (about 20/200) at this time.
I don't know if I ever answered his "WHY" question, but he did it correctly.
I have advocated that a preventive program be initiated with engineers at a four year college -- who had a starting refractive state of -3/4 diopters.
I think the question of "why" could be answered, and they would become successful.
But the study will never be conducted. WHY? Because I am an engineer, and because Dr. Kaisu IS DENIED PUBLICATION IN HER MEDICAL JOURNALS. That's why.
