The nurse is reviewing in age-related changes in the eye for a class. Which of these physiologic changes is responsible for presbyopia?
Decreased adaptation to darkness
Loss of lens elasticity
Decreased distance vision abilities
Degeneration of the cornea
The Correct Answer is B
A. Decreased adaptation to darkness: This change is related to decreased rod function but is not responsible for presbyopia.
B. Loss of lens elasticity: Correct. Presbyopia is caused by the age-related loss of elasticity in the lens, which reduces the ability to focus on near objects.
C. Decreased distance vision abilities: This may occur with other conditions like myopia but does not cause presbyopia.
D. Degeneration of the cornea: This can affect vision but is not responsible for presbyopia.
