Help! I can't see clearly anymore! I can't seem to focus on distant objects anymore! Everything looks blurry! I'm not too sure, but I think that it's because something has happened to me, and it has changed my ability to adapt to different focal lengths! I went online and checked it out, and this is what I generally found out. Maybe I'll go read up more about focal lengths and stuff tomorrow.
According to Helmholtz, the eye’s default state, with no external forces on it, is a round ball. This shape allows the eye to focus on near objects. The ring-shaped ciliary muscles pull the lens forward, allowing the eye to focus on distant objects. Studies have shown that in general, the higher the rate of myopia, the longer the length of the eye. This indicates that when the ciliary muscles focus on distant objects, the eye stretches and over a long period of time, accommodates to this shape. This is one of the mechanical models of the understanding of myopia. There are other mechanical models that can explain myopia, mostly involving the potential stresses forced onto the muscles and lens within the eye that causes them to shift into a permanent state of distant-object focus. Some models also indicate that image quality and balance i.e. proper lighting and contrast, etc. can also contribute to the onset and development of myopia.
