First, I support the concept of the plus, as the second-opinion. But you can not "share" prevention, with a person who believes that all prevention (at 20/40, self -1.0 diopter) is totally impossible.
Here are two video. The first, a graph of their "Box Camera" theory (Helmholtz- Donders) that has never been subjected to an objective scientific test.

The second concept, fully supports Todd's, concept and success.
I never recommend that a person even START with any prevention, unless he can read the 20/50 line, and can find in himself the motivation for long-term plus wearing.
This is absolutely NOT MEDICINE, and no one should ever think it is. There is not cure.
