Document Summary
We don"t pay attention to changes and disorders to the sensory system because they are: vision. Presbyopia - loss of vison as part of the aging process. Lens become less able to focused because they become stiff and thick. Cornea becomes thicker and results in distorted vision. Iris color to the eye fades as you get older (they say if someone is sick you just look into their eyes the eyes are the window to the soul ) How changes to vision affect behavior: decreased visual acuity cant see as well so need increased lighting, slower light and dark adaptation falls occur, so its very important to have night lamps. Identification of color cant tell the difference between colours. 50 years ago you would be blind with it but now you get surgery. No way to know you have it other than glaucoma test. A lot of pressure on optic nerve causing blindness: low vision.
