Why is blind spot devoid of ability of vision?

Explanation

### Step-by-Step Solution:

1. **Understanding the Blind Spot**: The blind spot, also known as the optic disc, is the area on the retina where the optic nerve exits the eye. This area does not contain any photoreceptors.

2. **Role of Photoreceptors**: The retina contains two types of photoreceptors: rods and cones. Rods are responsible for vision in low light conditions, while cones are responsible for color vision and function best in bright light.

3. **Absence of Photoreceptors**: In the blind spot, there are no rods or cones present. Since these photoreceptors are essential for detecting light and forming visual images, the absence of them in the blind spot means that this area cannot perceive visual stimuli.
