Scotopic vision is related with :-

Options

A. Cornea
B. Rods
C. Cones
D. Amacrine cell

Answer

**Step-by-Step Solution:**

1. **Understanding Vision Types**:
- There are two main types of vision: scotopic vision and photopic vision.
- Scotopic vision refers to vision under low light conditions, while photopic vision refers to vision under well-lit conditions.

2. **Characteristics of Scotopic Vision**:
- Scotopic vision is characterized by the ability to see in black and white.
- It occurs when there is insufficient light, such as in a dark room.

3. **Role of Photoreceptor Cells**:
- The human eye contains two types of photoreceptor cells: rods and cones.
- Rods are responsible for scotopic vision, while cones are responsible for photopic vision.

4. **Function of Rods**:
- Rods are sensitive to low light levels and allow us to see in dim conditions.
- They absorb light primarily in the green to blue range of the visible spectrum (approximately 490nm to 690nm).

5. **Conclusion**:
- Since scotopic vision is associated with low light and is mediated by rods, the correct answer to the question is "rods".

**Final Answer**: Scotopic vision is related to **rods**.
