loss of the same side of the visual field of both eyes; caused by damage to the visual cortex on only one side

caused by blockage of aqueous humor leading to increased intraocular pressure; causes damage to the retina and optic nerve

gel-like substance found posterior to the lens of the eye

clear, watery fluid contained in the anterior chamber of the eye

ability of the eye to focus specifically for close objects

unequal curvatures of the cornea or lens cause blurry images

also called the scleral venous sinus; where aqueous humor is reabsorbed into venous blood

purple pigment found in rods

light rays from distant images are focused behind the retina; "farsighted"

lens becomes hard & opaque causing vision to become hazy and distorted

reflexive movement of the eyes medially when we view close objects

pupils constrict due to bright light

area of greatest visual acuity; only cones present

flexible, biconvex crystal which focuses light on the retina

light rays from distant images are focused IN FRONT OF the retina; "nearsighted"

site where the fibers from the medial side of each eye cross over to the opposite side of the brain

caused by vitamin A deficiency; results in reduced rod function
