Movement of the eyes: vergence movements keep both eyes fixed on the same target, rapid, jerky saccadic movements shift your gaze from one point to another, pursuit movements allow us to maintain a moving object. Anatomy of the eye (i): the conjunctiva is a mucous membranes that line the eyelid, the cornea is the outer, front layer of the eye. It is transparent and admits light: the iris is a pigmented ring of muscles, the lens consists of several transparent layers. The ciliary muscles can change the shape of the pupil to allow the eye to focus, a process known as accommoda- tion: the pupil regulates the amount of light entering the eye. It is an opening in the iris: the sclera is opaque and does not permit entry of light, the interior lining of the eye is the retina. Photoreceptors called rods and cones are located here.
