उत्तर
When you look at an object very close to your eyes, the ciliary muscles of your eye contract and the eye lens becomes thick.
Explanation:
When viewing a nearby object, the ciliary muscles contract, which reduces tension on the lens. This makes the lens thicker (more convex), increasing its focal power so the image can be focused on the retina.
