The ability of the eye to focus on both, near and distant objects, by adjusting its focal length, is called the _____________ of the eye.

Correct option is A

Ans: (A) Accommodation

Explanation:
Accommodation is the ability of the eye to focus on both near and distant objects by adjusting its focal length.

Information Booster:

• Ciliary Muscles: The process of accommodation is controlled by the ciliary muscles of the eye, which adjust the shape of the lens to focus on objects at varying distances.
• Lens Shape: The lens changes shape to focus light on the retina, allowing the eye to clearly see objects at different distances.
• Presbyopia: A deficiency in accommodation can cause presbyopia, a condition commonly occurring with age, where the eye's ability to focus on near objects diminishes.
• Age-Related Changes: As individuals age, the flexibility of the lens decreases, making accommodation more challenging.

Incorrect Options Explanation:

• Suitability: Refers to how well something is suited or appropriate for a particular purpose, but does not relate to the eye’s ability to focus.
• Adjustment: A general term for making changes, but not specific to the process by which the eye changes focus between distances.
• Refractiveness: Refers to the bending of light as it passes through different materials (like the lens of the eye), but it does not specifically describe the eye’s ability to focus on objects.
