The bottom line is, putting on your prescription glasses helps you accomplish tasks, and they're also bad for your eyes. If you're going to wear them, don't try to get someone here to make you feel better about it, because you're only fooling yourself. If you diligently practice the exercises, occasionally wearing your glasses might not prevent you from recovering your vision. Glasses interfere with the visual biofeedback in that the clear vision they help produce suggests that everything is okay and that there is no severe misuse of the eyes going on. It leads to a mess that people must find their way out of as they relearn, without glasses, what really affects their vision positively or negatively. Glasses really aren't the problem; misuse of the eyes is the problem. But glasses cover up the problem and mislead you. How often will you participate in the illusion?
Try pinhole glasses if you need to wear something sometimes. They still have the drawback of helping to produce a sort of clear vision despite continuing misuse of the eyes, but people often find for whatever reason that wearing pinhole glasses results in a feeling of instant relief for the eyes, as if much of the eyestrain just disappears, whereas prescription glasses do not help produce the same beneficial feeling.
