Which condition is indicative of age-related degeneration in vision?

Age-related degeneration in vision can manifest through various conditions that often develop as individuals grow older. Each of the conditions listed—cataracts, presbyopia, and impaired night vision—are commonly associated with the aging process and contribute to the overall decline in visual function.

Cataracts occur when the lens of the eye becomes cloudy, leading to blurred vision and increased difficulty with glare. This condition is frequently seen in older adults and is directly linked to the aging process, making it an important indicator of age-related changes in vision.

Presbyopia is the gradual loss of the eye's ability to focus on nearby objects, primarily due to changes in the lens's flexibility. This condition typically begins in one's 40s and reflects the natural aging of the eye and its structures.

Impaired night vision, which may be caused by a variety of factors including changes in the retina or the lens, also tends to worsen with age, as the eye's ability to adapt to low-light conditions decreases.

Each of these conditions not only represents a common vision issue found in older populations but also highlights the different ways in which aging can affect visual capabilities. Therefore, recognizing that all these conditions are indicative of age-related degeneration leads to the understanding that they collectively signify the broader
