VCE Psychology Visual Perception Test RevisionCornea -ANSWER. the transparent, convex-shaped covering which protects the eye and helps to focus light rays onto the retina at the back of the eye Aqueous Humour -ANSWER. the watery fluid which helps to maintain the shape of the eyeball and provides nutrients and oxygen to the eye, as well as carrying away waste products. Pupil -ANSWER. not a structure in itself, but an opening in the iris that helps to control the amount of light entering the eye Iris -ANSWER. the coloured part of the eye consisting of a ring of muscles that expand or contract to change the size of the pupil and control the amount of light entering the eye Lens -ANSWER. a transparent, flexible, convex structure located immediately behind the pupil which plays a major role in focusing light onto the retina Ciliary Muscle -ANSWER. expand and contract, enabling the lens to automatically bulge to focus nearby objects onto the retina and flatten to focus distant objects onto the retina Vitreous Humour -ANSWER. the jelly-like substance which helps to maintain the shape of the eye and also helps focus light Retina -ANSWER. layer of neural tissue at the back of the eye that receives and absorbs light, and processes images for transmission to the brain Optic Nerve -ANSWER. transmits visual information from the retina to the primary visual cortex Accommodation -ANSWER. a depth cue involving the automatic focusing of the lens in the eye to adjust shape in response to changes in the distance of view from an object Binocular depth cue -ANSWER. a depth (or distance) perception cue requiring the use of both eyes Blind spot -ANSWER. a small area on the retina at the back of the eye where there are no photoreceptors so light cannot be detected Closure -ANSWER. a Gestalt principle. The perceptual tendency to mentally 'close up', fill in or ignore gaps in a visual image and to perceive objects as complete .
