Retina in a human eye acts like a

Options

A. lens in a camera
B. shutter in a camera
C. film on a camera
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Function of the Retina:**
- The retina is a layer of tissue located at the back of the eye. Its primary function is to receive light that the lens has focused and convert it into neural signals that are sent to the brain.

2. **Comparing the Retina to a Camera:**
- To understand what the retina acts like, we can compare it to a component of a camera. In a camera, there is a part that captures the image formed by the lens.

3. **Identifying the Camera Component:**
- In a camera, the lens focuses light to create an image, similar to how the eye lens works. However, the lens itself does not capture the image.

4. **Finding the Correct Comparison:**
- The part of the camera that captures the image is the film (or digital sensor in modern cameras). This is where the image is formed and stored, just like the retina in the human eye.

5. **Conclusion:**
- Therefore, the retina in a human eye acts like the film in a camera, as both serve as the surface where the image is formed.

**Final Answer:**
The retina in a human eye acts like the film in a camera.
