The loss of the eye's ability to change focus to see near objects. The reasons for this loss of the power of accommodation are not yet fully known. It is conventionally said to be due to the lens becoming less elastic with time. Presbyopia is associated with aging. It occurs in everyone.

"far-sightedness brought on by age," 1791, medical Latin, from Greek presbys "old man" (see presby-) + -opia, from ops "eye" (see eye (n.)). Related: Presbyopic.

(n) a reduced ability to focus on near objects caused by loss of elasticity of the crystalline lens after age 45

Part of the normal process of aging. As a person becomes older, we begin to lose the flexibility of the natural crystalline lens of the eye and weakness of the ciliary muscle. Presbyopia actually starts at about age ten. Most people do not begin to experience the effects of presbyopia until their forties. This loss of flexibility limits the ability [..]

Age-related difficulty focusing the eyes at close range, as the flexible lens of the eye becomes less elastic.

The normal decreasing Elasticity of the Crystalline Lens that leads to loss of accommodation.

The normal decreasing elasticity of the crystalline lens that leads to loss of accommodation.

An age-related vision condition in which the eye gradually loses the ability to focus on near objects.

A form of farsightedness in which it is difficult to focus on close objects or to read.
