I have a theory, I think the problem is the lack of range of eyes muscles. Most people who needed glasses are people who are not usually seeing long distance objects, these people usually stays in a confined space or usually reading or using cellphones, eventually the muscles used to focus objects becomes limited in range of motion. Imagine a camera who cannot focus, because of a failure resulting in a limited range of motion. Despite having no problems with the lenses, the camera remains out of focus this resulting in blurriness. I do think people need to get out, see long distance objects, not just remain in a confined space with close proximity objects like walls,etc. My vision returned to 20/20 after ditching eyeglasses and going outside, and if I am inside the office I picked location near windows and relax my eyes looking at distant objects.
