How Is a Human Eye Similar to a Camera?
A human eye and a camera have many similarities. The Boston University Physics website explains that the eye's pupil and retina are similar to the shutter and film of a camera. The pupil and shutter regulate light and the film and retina record images. The lens focuses light and creates an image in both the eye and the camera. The website notes that the human eye adjusts focus automatically but the camera lens must be adjust to focus images at different distances.
