Vision begins with light passing through the cornea and the lens, which combine to produce a clear image of the visual world on a sheet of photoreceptors called the retina. As in a camera, the image on the retina is reversed: Objects above the center project to the lower part and vice versa. Light rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape. In a normal eye, the light rays come to a sharp focusing point on the retina. The retina functions much like the film in a camera. From the cornea, the light passes through the pupil. The iris, or the colored part of your eye, controls the amount of light passing through.

January 23, 2006; reviewed for accuracy January 6, 2013. Introduction. Binocular Single Vision may be defined as the state of simultaneous vision, which is achieved by the coordinated use of both eyes, so that separate and slightly dissimilar images arising in each eye are appreciated as a single image by the process of fusion. The process of vision first starts with the light passing through the cornea. Since the cornea has a spherical surface it acts like a converging lens.
