Most insensitive part of the eye is called :

Options

A. blind spot
B. Eye lens
C. cornea
D. Ciliary Muscles

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the most insensitive part of the human eye.

2. **Identifying the Parts of the Eye**: To answer this question, we need to consider the various parts of the eye, such as the retina, lens, cornea, and blind spot.

3. **Analyzing the Blind Spot**: The blind spot is a specific area on the retina where there are no photoreceptor cells (rods and cones). This is where the optic nerve exits the eye, and since there are no cells to detect light in this area, it cannot perceive visual information.

4. **Comparing Other Parts**:
- The **lens** is responsible for focusing light and is sensitive to changes in shape and position.
- The **cornea** refracts light and is also sensitive to touch and pressure.
- The **retina** contains photoreceptors that are sensitive to light.

5. **Conclusion**: Since the blind spot lacks photoreceptor cells, it is the most insensitive part of the eye. Therefore, the answer to the question is the **blind spot**.

### Final Answer:
The most insensitive part of the eye is called the **blind spot**.
