ABSTRACT
Light rays are divergent when an object is up close. The crystalline lens becomes round to bring it into focus. When looking at an object less than 16 in. away, the lens bulges to its maximum. By maintaining that shape for an extended period, the “effort to see” becomes excessive. The eyeball would elongate to alleviate some of the stress placed on the ciliary muscle. The drawback with bringing the retina closer to the focal point (by elongating the sclera) rather than the focal point closer to the retina (by enticing the lens to bulge) is that the oblique muscles may not return to their relaxed state under normal conditions. The excessive tension of the oblique muscles produces a different neurological message for distant focusing. It is as if though you are still engaged in near focusing even when looking far away.
“Why am I nearsighted?” your clients may ask if they were told by their eye care specialists that they need glasses to make out objects far away. They may not get a definite answer—even if they searched online. There is a lack of a definitive theory. It is possible that there are several causes. The model that I am proposing attempts to address the question before seeking a treatment.
