Why the human eye is compared with camera?
उत्तर
The human eye can be compared to a camera as both functions by gathering, focusing, and transmitting the light through the lens for creating an image of an object.
- The iris of the eye controls the size of the pupil depending on the amount of light entering it.
- The pupil is like the eyehole of a camera which allows light to come in.
- Lens: It is a transparent, biconvex, and adjustable part of an eye, made up of protein. The lens with the help of the cornea refracts light focused on the retina, therefore creating images on it.
- The retina consists of photoreceptors and converts light rays into impulses to be sent to the brain. It is light-sensitive.
The retina is compared to the film in a camera.
