WebAlters the shape of the lens so that the eye can focus: Suspensory ligament: Attaches the ciliary muscle to the lens: The retina. Light passes through the eyeball to the retina. WebIt's just an assumption, for the sake of simplicity. We are just learning the basics of ray optics, so we are simplifying things to our convenience. Lenses don't always need to be symmetrical. Eye lens, as you said, isn't symmetrical. In fact, its aperture (diameter) can be changed, using the ciliary muscles inside our eyes.
