Question
Explain the role of the part of human eye responsible for power of accommodation of human eye.
Solution
The role of the ciliary muscles in the human eye, responsible for the power of accommodation, is to adjust the curvature of the eye lens. This adjustment allows the eye to focus on objects at different distances. When the ciliary muscles contract, the lens becomes thicker, decreasing its focal length to focus on near objects. Conversely, when the muscles relax, the lens becomes thinner, increasing its focal length to focus on distant objects. This process enables clear vision across a range of distances.
