What is a common sensory system change related to aging?

Development of cataracts is a common sensory system change associated with aging. As people age, the proteins in the lens of the eye can clump together, creating cloudy areas that interfere with light transmission. This can lead to blurred vision, difficulty with night driving, and increased sensitivity to glare. Cataracts are prevalent among older adults, and nearly everyone will develop them if they live long enough. The transformation of the lens can significantly impact daily activities, making it important for older adults to have regular eye exams to monitor eye health and address any issues promptly.

In contrast, enhanced evening vision and increased sensitivity to smells are not typical changes that occur with aging. Many adults experience a decline in their ability to see well at night and a decreased sense of smell as they age. Similarly, balance perception may not improve; instead, older adults often face challenges with balance, which can increase the risk of falls. Understanding these sensory changes is crucial for aging individuals and their caregivers to ensure proper support and management of health issues.
