Which visual change is common with aging and can impact color perception?

The correct answer highlights a significant change in the visual system with aging that affects how colors are perceived. As people age, the lens of the eye can undergo various changes, including yellowing, which can alter the way colors appear. This phenomenon is related to changes in the lens's ability to transmit light effectively and affects color discrimination, making it challenging for older adults to distinguish between shades, particularly blues and greens.

While decreased visual acuity contributes to overall visual perception difficulties, it is the specific alterations in the lens that have a direct impact on color perception. Other common issues with aging, such as increased glare sensitivity and presbyopia, while relevant, are less directly tied to the perception of color itself. Increased glare sensitivity can affect how comfortable one feels in bright lighting but does not directly alter the color perception. Presbyopia relates more to the ability to focus on near objects rather than how colors are seen. Therefore, focusing on lens changes provides a clearer understanding of aging's impact on color perception.
