Similarity between Human Eye and Camera
Human eye is more like a camera because both have the ability to capture images and focus on objects. Here are some key similarities between the human eye and a camera:

1. Lens System
- Both the human eye and a camera have a lens system that helps in focusing light onto a light-sensitive surface.
- The lens in the human eye is called the cornea and the lens in a camera can be adjusted to focus on objects at different distances.

2. Aperture
- Both the human eye and a camera have an aperture that controls the amount of light entering the system.
- The iris in the human eye acts like an aperture by adjusting the size of the pupil, while a camera has a physical aperture that can be adjusted.

3. Light-sensitive Surface
- In both the human eye and a camera, the light is focused onto a light-sensitive surface where the image is formed.
- The retina in the human eye functions as the light-sensitive surface, while a camera uses a digital sensor or film.

4. Image Processing
- Both the human eye and a camera process the captured images to form a clear and detailed image.
- The human brain processes the visual information received by the eye, while a camera processes the captured image using software algorithms.

Conclusion
In conclusion, while the human eye shares similarities with a microscope and telescope in terms of its ability to focus on objects, it is most closely related to a camera due to its structure and functioning as a tool for capturing and processing images.
