How might vision typically change with aging?

• A. Improvement in night vision and color perception
• B. Common changes include presbyopia, cataracts, and age-related macular degeneration
• C. Reduction in vision only in one eye
• D. Vision remains stable throughout aging

Answer: (B)

As individuals age, common changes to vision occur due to various factors affecting the eye. Presbyopia, which is the gradual loss of the eye's ability to focus on nearby objects, typically begins in the early to mid-40s. This condition arises because the lens of the eye becomes less flexible over time. Cataracts, another prevalent condition in older adults, lead to clouding of the lens, consequently causing blurred vision, glare, and difficulty seeing at night. Age-related macular degeneration is a significant concern as it affects the central part of the retina (the macula), leading to vision distortion or loss in the central visual field.

These changes are part of the normal aging process and highlight the need for regular eye examinations for older adults. Regular screenings can help detect these conditions early, allowing for more effective management or treatment. The presence of multiple conditions such as presbyopia, cataracts, and macular degeneration collectively reflects the multifaceted nature of visual changes with aging, making this answer the most accurate among the options provided.
