Psychological Development Across the Lifespan

Middle Adulthood (40–60)

What sensory changes occur in middle adulthood?

Presbyopia, which means “old eyes” in Greek, refers to a common condition encountered in middle adulthood. The lens of the eye becomes less flexible, reducing the ability of the eye to focus on close objects. People in their forties frequently have difficulty reading due to presbyopia. They must hold reading material at arm’s length to focus on the letters. Consequently, many people this age buy reading glasses for the first time. There are also changes in hearing, although these are not as noticeable as the changes in vision. Loss of sensitivity to high-pitched sounds can begin in middle adulthood although hearing loss is generally more pronounced in later adulthood.
