Following changes occur when we try to look at a distant object except

Options

A. 1.Suspensory ligaments are streched
B. lens becomes more curved
C. lens becomes thin and it's radius of curvature increases
D. cilliary muscles are relaxed

Answer

To solve the question regarding the changes that occur when we try to look at a distant object, we need to analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Understand the Mechanism of Vision**:
- When focusing on a distant object, the eye undergoes specific changes to adjust the lens for optimal focus.

2. **Evaluate Each Statement**:
- **Statement 1**: "Suspensory ligaments are stretched."
- **Analysis**: This is true. When looking at distant objects, the ciliary muscles relax, causing the suspensory ligaments to stretch, which flattens the lens.

- **Statement 2**: "Lengths become more curved."
- **Analysis**: This is false. When focusing on a distant object, the lens becomes less curved (flatter) to reduce its optical power. Therefore, this statement does not occur.

- **Statement 3**: "Lens become thin and its radius of curvature increases."
- **Analysis**: This is true. The lens becomes thinner when focusing on distant objects, and the radius of curvature increases as it flattens.

- **Statement 4**: "Ciliary muscles are relaxed."
- **Analysis**: This is true. The ciliary muscles relax when focusing on distant objects, allowing the lens to flatten.

3. **Identify the Incorrect Statement**:
- From the analysis, the only statement that does not occur when looking at a distant object is Statement 2: "Lengths become more curved."

4. **Conclusion**:
- The answer to the question is that the statement "Lengths become more curved" is the exception when trying to look at a distant object.

### Final Answer:
The correct answer is **Statement 2**: "Lengths become more curved."
