Which functional change describes color vision in older adults?

• A. Vision for low-tone colors may be difficult
• B. Color vision improves with age
• C. Color vision remains perfect
• D. Color perception is enhanced in dim light

Answer: (A)

Color vision tends to decline with age because the eye undergoes changes such as the lens becoming thicker and more yellow, which reduces transmission of blue light and dulls color discrimination. This means subtler or low-saturation colors can be harder for older adults to distinguish. That’s why the statement about vision for low-tone colors being difficult best describes the typical functional change in color vision with aging. The other ideas don’t fit: color vision does not improve with age, it does not stay perfectly intact, and color perception isn’t enhanced in dim light—older adults often have reduced color discrimination, especially in low-light conditions.
