The image on the retina remains for

Options

A. 20 s
B. 10 s
C. `1/10s`
D. `1/16s`

Explanation

To solve the question regarding how long the image on the retina remains, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Eye Structure**:
- The human eye consists of several parts including the cornea, lens, and retina. The cornea and lens focus light onto the retina, where the image is formed.

2. **Image Formation on the Retina**:
- When light enters the eye, it is refracted by the cornea and lens, creating an image on the retina. This image is inverted and reduced in size.

3. **Duration of Image Retention**:
- The question asks how long this image remains on the retina. The image does not stay indefinitely; it is processed by the brain.

4. **Time Frame for Image Persistence**:
- The image on the retina remains for a very short duration. Specifically, it is retained for approximately 1/16th of a second. This is the time it takes for the brain to process the visual information before it disappears.

5. **Conclusion**:
- Therefore, the answer to the question is that the image on the retina remains for **1/16th of a second**.

### Final Answer:
The image on the retina remains for **1/16th of a second**.
