What condition is characterized by the inability to focus on nearby objects due to aging?

Presbyopia
Strabismus
Amblyopia
Esophoria

The correct answer is: Presbyopia

The condition characterized by the inability to focus on nearby objects due to aging is presbyopia. This occurs as the lens of the eye becomes less flexible over time, making it more difficult to adjust focus to see close objects clearly. Typically, presbyopia begins to affect individuals in their mid-40s to early 50s, making daily tasks such as reading and sewing challenging without corrective lenses. It is a common and expected change in vision associated with the natural aging process. In contrast, strabismus involves misalignment of the eyes, where one or both eyes may turn in different directions, affecting binocular vision. Amblyopia refers to a vision development disorder where one eye does not properly connect with the brain, often leading to decreased vision in that eye. Esophoria is a type of eye misalignment where one eye tends to turn inward but can remain aligned under certain conditions. These other conditions are not related to the natural aging process and specifically the loss of near vision ability.
