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 option provided and determine which one does not occur. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Mechanism of Vision
When we look at distant objects, our eyes undergo specific adjustments to focus properly. This involves changes in the lens shape and the state of the ciliary muscles.

### Step 2: Analyze Each Option
1. **Suspensory Ligaments are Stretched**:
- When focusing on distant objects, the ciliary muscles relax, which causes the suspensory ligaments to stretch. This is a correct statement.

2. **Lens Becomes More Curved**:
- For distant vision, the lens actually becomes thinner and less curved. A more curved lens is associated with focusing on nearby objects. Therefore, this statement is incorrect.

3. **Lens Becomes Thin and Its Radius of Curvature Increases**:
- When focusing on distant objects, the lens does become thinner, which is correct. The radius of curvature decreases, not increases, but the statement is misleading. However, the main point is that the lens becomes thin, which is true.

4. **Ciliary Muscles are Relaxed**:
- This is true; when looking at distant objects, the ciliary muscles relax, allowing the lens to flatten.

### Step 3: Identify the Incorrect Statement
From the analysis, the option stating that the "lens becomes more curved" is incorrect when trying to focus on distant objects. Instead, the lens becomes thinner and less curved.

### Conclusion
The correct answer to the question is the option that states "Lens Becomes More Curved," as this does not occur when we try to look at a distant object.
