Accomodation for year vision happens how?
a) in focus-light rays from distant objects are more parallel, they focus onto retina when lens is less curved.
b) out of focus-diverging light rays from near objects do not focus on the retina when the ciliary muscles are relaxed.
c) bringing into focus-firing of parasympathetic nerves, contracted ciliary muscles, slackened zonular fibers, rounded lens. Accomodation increases the curvature of lens, focusing the image of near objects onto the retina.
