Equally - and being fair - ask why everyone fails - when they are at 20/50.
The major reason - is that they do not, "trust" the concept of prevention. The next reason - the refuse to set up a Snellen - and read it objectively, as described in this video.
https://www.youtube.com/watch?v=1he8JGH7vBAThen they will say, " Otis, you are trying to make money off me". Fair enough.
But my reasons, was to help my sister's three children, always AVOID GETTING DEEPER THAN 20/40. (Always pass the DMV, and self-measure their own refraction - if they wished.
They took the PROVEN, -1/2 diopter per year, that your refraction "goes down" for each year in school, very seriously.
That mean that the started, or re-started wearing the plus, when they personally saw their visual acuity "going down" towards 20/40. This is absolutely not medicine, and the eye is not, "medically defective", in that range.
That is what you must understand - if you wish to avoid entry into myopia.
This is what Brian Severson did, when he asked for help to get back to 20/20 (as a pilot).
I just provided objective science, and said that no OD would ever help him, "get back out of it".
But he did not, "argue with me". He did not, "complain" about wearing the plus, for being, "in fear" of wearing of plus, or that the plus (for prevention) would, "hurt his eyes" in some way.
That is in fact, what STOPS all ODs and MDs from saying anything at all.
That is a matter of, "your fear" that you must understand.
But what is the plus about? It is about the natural eye being highly responsive to, "near" habits of children.
Correctly understood, and the "plus" is like living out doors, most of the time.
But that is the concept people hate. I hate the idea that I must wear a plus (always) for prevention, when I am still passing the 20/50 to 20/60 line.
In my opinion, if you are in Junior High School - that is your last chance to stay out of it - and get back to 20/20.
I thank Todd - for his success. You KNOW he is not attempting to, "make money off you", or sell you anything at all.
Enjoy !
