Area of retina devoid of rods and cones is

Options

A. Yellow spot
B. Blind spot
C. Blue spot
D. Black spot

Answer

To answer the question regarding the area of the retina that is devoid of rods and cones, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Retina**: The retina is the light-sensitive layer at the back of the eye that contains photoreceptor cells known as rods and cones. Rods are responsible for vision in low light, while cones are responsible for color vision and detail in brighter light.

2. **Identify the Function of Rods and Cones**: Since rods and cones are essential for vision, the area that lacks these cells would not be able to detect light or contribute to visual perception.

3. **Locate the Area Without Photoreceptors**: The area of the retina that is devoid of rods and cones is where the optic nerve exits the eye. This region does not contain any photoreceptor cells.

4. **Name the Area**: This specific area is commonly referred to as the "blind spot." It is called this because it does not register visual information, leading to a gap in the visual field.

5. **Conclude the Answer**: Therefore, the area of the retina devoid of rods and cones is known as the blind spot.

### Final Answer:
The area of the retina devoid of rods and cones is the **blind spot**.
