Which of the following best describes the process of accommodation in the human eye?
Options
A The process where the iris dilates or constricts to control the amount of light entering the eye.
B The adjustment of the eye's focal length by changing the lens's curvature to focus on objects at different distances.
Correct Answer
C The ability of the eye to adapt to varying levels of light intensity.
D The mechanism by which the eye processes color information.
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to the text, 'This process is called accommodation.' It is described as the ciliary muscle increasing tension and contracting, causing the lens to bulge and its radius of curvature to change, thereby adjusting the focal length to form a sharp image of closer objects on the retina.

Hint

Accommodation is about focusing on objects at different distances.
