Dry eye syndrome affects many older adults, resulting from age-related changes in tear production and ocular health. Effective management can improve your quality of life.
Dry eye syndrome is an eye condition marked by insufficient or poor-quality tears that leads to discomfort, blurred vision, and irritation. As we age, our eyes naturally undergo changes that make dry eye increasingly common and more severe, affecting millions of older adults worldwide. Understanding the link between aging and dry eye is essential for preserving vision and maintaining quality of life.
Aging is a major risk factor for developing dry eye disease, with individuals over 50 experiencing a higher prevalence and severity of symptoms. Natural aging brings about a gradual reduction in tear production and alterations in the oil and mucus components that keep the ocular surface healthy. These age-related changes affect several ocular structures, including the lacrimal glands, meibomian glands, and conjunctiva, ultimately compromising tear film stability.
The lacrimal glands are responsible for producing the watery layer of our tears. As we get older, these glands suffer from acinar atrophy, fibrosis, and chronic inflammation. This deterioration results in reduced tear production, which means that the eyes receive less lubrication to keep them comfortable and clear of irritants.
The meibomian glands, located along the eyelids, produce the lipid layer that prevents rapid tear evaporation. With age, these glands gradually lose function due to gland atrophy, reduced meibocyte differentiation, and blockage of the gland orifices. Their decline results in thinner lipid layers, causing the tears to evaporate quickly and contributing to the overall instability of the tear film.
The conjunctiva, a membrane covering the white part of the eye, contains goblet cells that produce mucins, critical for a smooth, stable tear film. Although the number of goblet cells may not decrease dramatically with age, their functionality does decline, reducing the protective mucin layer. This deterioration compromises the ocular surface and can result in increased irritation and inflammation.
Aging is accompanied by a state of chronic, low-grade inflammation often called “inflammaging.” This persistent inflammation can affect all components of the ocular surface, including the lacrimal and meibomian glands, leading to diminished tear production and ocular surface damage.
Oxidative stress also plays an important role in the development of dry eye syndrome. With advancing age, the body’s ability to counteract reactive oxygen species diminishes, and the accumulation of oxidative damage impairs the cells responsible for tear production and ocular surface maintenance. Both inflammation and oxidative stress exacerbate dry eye by impairing the healing process and accelerating tissue deterioration.

Older adults are more likely to develop systemic conditions such as diabetes, hypertension, and autoimmune disorders, all of which can have secondary effects on the eyes. These underlying conditions can further reduce tear production or worsen the quality of the tear film, thus increasing the risk of dry eye.
Moreover, the number of prescription medications tends to increase with age. Many common drugs—including antihistamines, antidepressants, blood pressure medications, and treatments for Parkinson’s disease—list dry eye as a potential side effect. This polypharmacy can compound the already elevated risk in older adults.
Dry eye syndrome does more than just cause physical discomfort; it can profoundly affect daily activities and overall quality of life. Persistent irritation, blurry vision, and pain can interfere with everyday tasks, from reading and driving to working on digital devices.
The condition can also lead to secondary complications, such as an increased risk of eye infections and even falls, particularly in those with poor vision. Older adults with untreated dry eye may face a higher incidence of depression and decreased overall well-being due to persistent frustration and discomfort.
