Question

Assertion (A): An eye can focus the images of the distant objects as well as the nearby objects on its retina by changing the diverging power of its lens.

Reason (R): The ability of an eye to focus the distant objects as well as the nearby objects on the retina by changing the converging power of its lens is called accommodation.

Options

• Both A and R are true and R is correct explanation of the assertion.

• Both A and R are true but R is not the correct explanation of the assertion.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

The assertion is false because the crystalline eye lens is a convex lens, which adjusts its converging power, not diverging power. The reason is true because the ability of the eye to change its lens curvature and converging power to focus both near and far objects on the retina is the exact definition of accommodation.
