What is a common characteristic of tear film abnormalities in aging?

A common characteristic of tear film abnormalities in aging is decreased tear production. As individuals age, the lacrimal glands often become less efficient at producing tears, leading to a reduction in the quantity of tears available to maintain a stable tear film. This decrease in tear production can result in a variety of discomforting symptoms, including dryness and irritation of the eyes, commonly referred to as dry eye syndrome.

The decline in tear production is primarily due to age-related changes in the ocular surface and the lacrimal system. Hormonal changes, particularly in women during and after menopause, can also contribute to reduced tear volume. Maintaining a healthy tear film is crucial for optical clarity and comfort; thus, understanding this characteristic of aging is essential for eye care professionals when diagnosing and managing age-related ocular surface disorders.
