Document Summary

Perception: how we perceive the stimulation of our sensory receptors. Visual agnosia: inability to identify objects visually but objects can be identified using other senses. Prosopagnosia: a subtype of visual agnosia where patients are unable to recognize. All faces, including their own but they can recognize the people through other characteristics such as their voice, mannerisms, etc. Can even recognize that they are faces but not whose face it is. Cornea: protective bump at the front of the eye that also helps focus light onto the retina 80% of focusing occurs here and is fixed in place. Lens: elastic, crystalline structure that accounts for the other 20% of light focussing exact spot nearby objects. Nearsightedness either the eyeball is too long and/or the cilliary muscles contract cannot focus because the lens has reached maximum curvature too much so the lens focuses light in front of the retina.
