As we age, our eyes lose the ability to accommodate, causing many people to need reading classes. Which structure of the eye is likely affected?

• B. Lens.
• C. Retina.
• D. Pupil.

Answer: (B)

Verified step by step guidance

1. Understand the concept of accommodation in the eye: Accommodation is the process by which the eye changes optical power to maintain a clear image or focus on an object as its distance varies.
2. Identify the structures of the eye involved in accommodation: The lens is the primary structure that changes shape to focus light on the retina, allowing us to see objects clearly at different distances.
3. Consider the effects of aging on the eye: As we age, the lens becomes less flexible, making it harder to change shape and focus on close objects, a condition known as presbyopia.
4. Evaluate the options given: Cornea, Lens, Retina, Pupil. The cornea and pupil do not change shape for accommodation, and the retina is the light-sensitive layer at the back of the eye, not involved in changing focus.
5. Conclude that the lens is the structure affected by aging, leading to a decreased ability to accommodate and the need for reading glasses.
