The blind spot is the region where

Options

A. Image is dim
B. Image is formed in strong light
C. Optic disc is present
D. Image is formed during the dark.

Answer

**Step-by-Step Solution:**

1. **Understanding the Blind Spot**: The blind spot in the eye is a specific area on the retina where there are no photoreceptor cells (rods and cones). This absence of photoreceptors means that no visual information can be detected in this area.

2. **Location of the Blind Spot**: The blind spot corresponds to the optic disc, which is the point where the optic nerve exits the eye. This is also where the retinal blood vessels enter the eye.

3. **Implications of the Blind Spot**: Since there are no photoreceptor cells in the blind spot, any image that falls on this area cannot be perceived, leading to a gap in the visual field. This is why it is referred to as the "blind spot".

4. **Conclusion**: Therefore, the blind spot is the region in the eye where no photoreceptor cells are present, resulting in a lack of vision in that specific area.

**Final Answer**: The blind spot is the region where no photoreceptor cells are present.
