The common resolution for the human eye in the central vision is A cameras come in the rage of mega pixels, meaning the eye has a. State the similarities between eye and lens camera. State the similarities between Next: List the parts of the human eye. Previous: Explain the. Strictly speaking, a camera's lens is too simple to be comparable with the whole eye; however, an entire camera can meaningfully compared to the human.

However, though there are many similarities between cameras and eyes, they are by no means identical. This transparent like clear jelly structure sits to the front of the eye and has a spherical curvature.

The lens of a camera is also transparent glass and sits at the front of the body. Like the cornea, the lens also maintains a spherical curvature.

The corneal and lens curvature allows for the eye and camera to view, though not in focus, a limited area to both the right and the left. That is, without the curve, the eye and camera would see only what is directly in front of it.

The Differences Between the Human Eye & a Camera Lens

Iris and Aperture The aperture is to the camera as the iris is to the eye, and this reveals one of many similarities between cameras vs. The aperture size refers to how much light is let into the camera and will ultimately hit the sensor or film.

As with the human eye, when the iris contracts itself, the pupil becomes smaller and the eye takes in less light. When the iris widens in darker situations, the pupil becomes larger, so it can take in more light.

The same effect happens with the aperture; larger lower aperture values let in more light than a small higher aperture value.

In contrast, the human cornea can change its shape to focus on close or distant objects. Muscles inside the eye pull on the cornea to flatten it or relax to allow it to become more convex. While high-technology lenses are being developed that can mimic this property, they're not commonly available yet.

Material The lens of a camera is typically made from a hard, transparent material. In the past, glass was usually used for camera lenses; nowadays they are often made from plastics, which are cheaper and less prone to cracking or smashing.

The human cornea, in contrast, is made from a soft organic substance. Complexity A camera lens alone is a relatively simple structure.

While it may require significant technical and manufacturing know-how to create one, a lens is in essence a curved section of transparent material with a frame that allows it to be attached to the camera.

The eye, on the other hand, includes not just a lens but numerous complex structures necessary for sight.
