Document Summary
Ch. 15 physical and cognitive development in middle adulthood. Around age 60, the lens loses its capacity to adjust to objects at varying distances entirely, a condition called presbyopia ( old eyes ) Second set of changes limits ability to see in dim light, which declines at twice the rate of daylight vision. A disease in which poor fluid drainage leads to a buildup of pressure within the eye, damaging the optic nerve. Presbycusis ( old hearing ): although some conditions run in families and may be hereditary, most are age-related. Around age 50, noticeable decline in sensitivity to high-frequency sounds, which gradually extends to all frequencies. Men"s hearing tends to decline earlier and more rapidly than women"s, a difference associated with cigarette smoking, intense noise and chemical pollutants in some male-dominated occupations, and high blood pressure and cerebrovascular disease, or strokes that damage brain tissue. Epidermis: protective layer, where new skin cells are constantly produced.
