Abstract
IN popular discussion the analogy is frequently drawn between the structure of the human eye and the mechanism of a camera. These two optical systems bear a superficial resemblance because, in each case, light rays reflected from distant objects enter an iris-diaphragm before actuating a photo-sensitive surface. Important examples of the many cues available for recognizing features of the immediate environment indicate variation in the sizes of objects in accordance with their locations in depth. Thus when considering the ability of human beings to perceive stimuli present in the field of vision, it is necessary to determine the sizes of the images formed on the retina of the eye.
