Here are the key points to remember:
While the idea of not wearing glasses is fundamentally a good instinct, we have to consider the severity of the myopia, and the focal distance in question. If you are -3D and don’t wear glasses just for close-up, that is an excellent idea. If you are a -6D, not wearing glasses at close-up might have you end up with neck and shoulder pain (unnecessarily), being so close to the screen.
Likewise, being a -3D not wearing glasses for distance vision, accomplishes nothing. Now everything is always blurred, it is frustrating both to you consciously, and your visual processing system. If you are a -6D and never wear glasses, rather than fighting myopia, you probably end up falling into an open manhole cover one day.
What we want, instead, is prescription(s) that cover just the visual range we need, for close-up, and for distance. This means two prescriptions (for a lot of us), both of which allow us to see clearly for their applicable distance, but include a blur horizon (at the maximum useful distance, we start to get some blur).
Bates Method is a bit of a silly proposition on several levels. First, exercise is much less effective than lifestyle and habit changes (as I advocate in the #endmyopia Method). Second, the premise of living with blur, accomplishes nothing.
Here is a recent forum question, which covers this subject quite appropriately:
Yesterday I started noticing, after putting on the full -5 diopters for a couple minutes in the morning, that I was suddenly very aware of the remaining blur when I wear -4 diopters. To follow your program, I went ahead and ordered both a reduced prescription for near use and a full -4.5 prescription for distance, but they are not expected to arrive for two weeks.
In the meantime, should I wear the slightly reduced -4 or the too-strong -5 diopters? I’m worried that, although I see razor-sharp with the -5, they will make my eyes worse since they are in fact too strong for me.

The blur horizon, in a differential prescription, is usually somewhere around 50cm (depending on what’s ergonomically comfortable for you). So you can see sharply within the range of where you are reading/working, but if you move back till there is some blur, you are still within the comfortable ergonomic range of your work. This way you have the correct prescription to work on active focus, and also the lowest possible prescription to see clearly.
With the normalized prescription, it is much the same story. Decide where you need your blur horizon, choose prescription accordingly. You want part of your vision to give you the option for some blur, that you can then make an effort to clear. The distance of this varies from case to case, but the common theme is always the same – blur = strain. We don’t want strain. We do want an accessible blur horizon for stimulus work, and to confirm that we have the lowest applicable prescription.
I am glad to have this forum for discussion. There are some interesting topics coming up, and interaction happening (I am quite excited to see this). I hope that this is helpful to you in uncovering the flaws in various methods, both the standard modern single prescription theory, and old concepts like Bates Method.
