Does the Human Eye Function Like A Camera?
We think of the human eye as a natural organ and the camera as a purely mechanical device with little relationship to the human body, yet the functioning of the eye and a camera are remarkably similar and in many ways. The human eye can be compared to a camera that gathers, focuses, and transmits light through a lens to create an image of the environment. We can think of the eyes as an organic camera (or is it that a camera is mechanical eye?). The eye is essentially a closed sphere with an adjustable opening at the front (lens) and strikes the retina at the back of the eye (the “film”). Like a camera, the eye is able to refract light and produce a focused image that can stimulate neural responses and enable the ability to see. Eyes (and cameras) receive external information from the outside environment (light) and process it internally. Eyes use biochemical processes to convert light into neural signals. Cameras rely on the chemical compounds of film emulsions to convert light into st
