In adjusting for near vision, the pupils constrict, die lenses become more convex, and the eyes converge; in adjusting for far vision, the reverse changes occur. The ability of the eye to accommodate decreases with age.One of the changes that take place when the eye adjusts to bring light rays from an object to focus on the retina. This involves a change in the size of the pupil, convergence or divergence of the eyes, .and either a decrease or an increase in the convexity of the lens depending on the previous condition of the lens.The adaptation of the eyes for close-up vision involves pupils narrowing, eyes coming closer together, and the lenses becoming more curved.
