Human Eye and Camera both are similar things but are used in different ways, In this story, we will talk about the Differences & Similarities between human eye and camera.

An eye and a camera both have lenses and light-sensitive surfaces. Your iris controls how much light enters your eye. Your lens helps focus the light.

How are an eye and a camera similar?

1. Light enters the eye through the pupil. 2. The iris regulates the amount of light entering the eye. 3. Focus light and image on the retina in the eye. 4. The eye contains a lens. 5. There is a choroid that absorbs light and limits reflection in the eye.

There are many SIMILARITIES between Human eye and camera

1. Human Eye

1. Light also enters the camera through the aperture. 2. The amount of light is also regulated in-camera with the diaphragm. 3. Focus light and image on film in the camera. 4. camera also contains a lens. 5. there is also black paint in the camera which absorbs lights and limits reflections.

 2.Camera

1. Focal length of the human eye lens can be changed. 2. Retina retains the impression of an image for only 1/16th of seconds. 3. The Same retina can be used for viewing unlimited images. 4. Image is formed on the retina which is further processed in the brain.  

There are many DIFFERENCE between the human eye and camera

1. Human Eye 

1. Focal length of the camera lens is fixed. 2. Photographic film of camera retains the image permanently. 3. A photograph has to be changed for getting the next image. 4. Image is formed on the photographic film and processing can be done through computer.

 2.Camera

Both the eye and camera have the ability to focus on one single object and blur the rest, whether in the foreground (shallow depth of field) or off at a distance. Likewise, the eye can focus on a larger image, just as a camera (greater depth of field) can focus and capture a large scape. 

Focus in Eyes and Camera

The retina sits at the back of the eye and collects the light reflected from the surrounding environment to form the image. The same task in the camera is performed either by film or sensors in digital cameras. This process underpins both how cameras work and how eyes work.
