Presbyopia is an age-related condition that specifically affects the eye's ability to focus on close objects. This occurs due to a loss of elasticity in the lens of the eye, making it difficult to adjust focus when reading or doing tasks that require seeing things up close. As people age, they often find that they need to hold reading material farther away to see it clearly, which characterizes the common affliction of near vision.

Unlike night vision, which is primarily affected by changes in rod cells in the retina, or depth perception, which is influenced by various factors including the shape of the eye and brain processing, presbyopia distinctly limits the ability to see clearly at close distances. Color perception can also change with age, but this is not as directly related to the structural changes that cause presbyopia. Thus, when considering the effects of aging on vision, near vision loss due to presbyopia is the primary concern that surfaces.
