Contraction in suspensory ligaments represents:-

Options

A. Object situated near by
B. Object situated at a distance
C. No change in lens diameter
D. Object may be near or at a distance

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Ciliary Muscles and Suspensory Ligaments:**
- The ciliary muscles are responsible for controlling the shape of the lens in the eye. They are connected to the lens via suspensory ligaments.

2. **Contraction of Ciliary Muscles:**
- When we focus on an object that is nearby, the ciliary muscles contract. This contraction leads to a change in the tension of the suspensory ligaments.

3. **Effect on Suspensory Ligaments:**
- As the ciliary muscles contract, the suspensory ligaments relax. This relaxation allows the lens to become thicker.

4. **Resulting Lens Shape:**
- A thicker lens is better suited for focusing on nearby objects. Therefore, when the suspensory ligaments relax, it facilitates near vision.

5. **Contraction of Suspensory Ligaments:**
- Conversely, when we focus on distant objects, the ciliary muscles relax. This relaxation causes the suspensory ligaments to contract.

6. **Effect on Lens for Distance Vision:**
- When the suspensory ligaments contract, they pull on the lens, making it thinner. A thinner lens is ideal for focusing on objects that are far away.

7. **Conclusion:**
- Therefore, the contraction of the suspensory ligaments represents the process of focusing on distant objects.

**Final Answer:**
The contraction in the suspensory ligaments represents the ability to focus on distant objects.
