WebbThe humans’ eyes are both set on the front of the face, permitting binocular vision. Each eye has a field of view, which is the area that an individual can see when one closes an eye. The center of the eyes’ fields of view overlaps with one another, although visual information in the periphery can only be detected by one eye. WebbFigure 1. (a) Rhodopsin, the photoreceptor in vertebrates, has two parts: the trans-membrane protein opsin, and retinal. When light strikes retinal, it changes shape from (b) a cis to a trans form.
