What describes the vision change where nearsighted individuals also experience difficulty due to aging?

The scenario described refers to a condition commonly known as presbyopia, which occurs as people age and presents additional visual challenges. Bifocal vision is closely associated with correcting both nearsightedness (myopia) and presbyopia, as it allows individuals to see clearly at multiple distances.

Bifocals contain two distinct optical powers: one for distance vision and one for close vision, addressing the visual difficulties experienced by persons who are nearsighted and also find it challenging to see objects up close as they age.

Other conditions, such as astigmatism, hyperopia, and myopia, do not encompass the dual challenges of nearsightedness and age-related vision loss simultaneously. Myopia specifically refers to nearsightedness, hyperopia relates to farsightedness, and astigmatism involves an irregular curvature of the eye that leads to blurred vision at all distances. Thus, recognizing the need for multifocal lenses like bifocals for those who face both of these challenges makes it the correct choice in this context.
