What is a possible consequence of structural changes in the eye for older adults?

Night vision difficulties can arise as a result of structural changes in the eye that occur with aging. As individuals get older, the lens of the eye can become less flexible and the pupil may not constrict as effectively, leading to reduced ability to adapt to changes in light levels. This can result in challenges with seeing in dim lighting conditions, such as difficulty driving at night or in poorly lit environments.

Additionally, age-related changes such as cataracts can further obscure vision, contributing to these difficulties. While some older adults may experience increased light sensitivity, reduced clarity of vision, and a potential need for corrective lenses increases rather than decreases, which reinforces the likelihood of night vision difficulties as a significant consequence of aging in relation to eye structure.
