Final answer:
During eye accommodation, the lens of the eye adjusts to maintain a clear image on the retina. For close vision, the lens becomes thicker and more converging, while for distant vision, it is relaxed. This allows the eye to focus on near and far objects accordingly.
Step-by-step explanation:
During eye accommodation, when you are looking at a far away object and then look at a near object, the lens of the eye adjusts to maintain a clear image on the retina. For distant vision, the lens is relaxed and has its smallest power. But for close vision, the lens becomes thicker and more converging (more powerful) with the help of the ciliary muscle surrounding it. This allows the eye to focus on the near object and produce a clear image on the retina.
