Dry eye disease can affect adults at many stages of life, though it becomes increasingly common with age. Many older adults notice that their eyes feel drier, more irritated, or more tired than before, especially during reading, screen use, or prolonged visual tasks.
This increase is not caused by a single factor alone. Ageing affects several parts of the eye and tear system at the same time, including tear production, eyelid function, and tear film stability.
This article explains why dry eye disease becomes more common with age, what changes may happen to the tear film and eyelids, and how patients can better understand age-related dry eye symptoms.
Understanding Dry Eye Disease in Adults
Dry eye disease happens when the eyes do not stay properly lubricated and protected. This may occur when the eyes do not produce enough tears, when tears evaporate too quickly, or when the tear film becomes unstable.
The tear film is the thin protective layer that covers the front surface of the eye. It helps keep the eye moist, comfortable, and clear. When this layer becomes unstable, the eye surface may become irritated.
Why Age Is a Risk Factor for Dry Eye Disease
Ageing can affect several parts of the tear system. Tear production may reduce, the eyelid oil glands may become less efficient, and the eye surface may become more vulnerable to irritation.
This is one reason dry eye disease can develop gradually. Instead of appearing all at once, symptoms may become more noticeable over time, especially during screen use, reading, contact lens wear, or exposure to wind and air-conditioning.
How Ageing Affects Tear Production
One of the main age-related changes is reduced tear production. The watery part of the tear film, known as the aqueous layer, helps keep the eye surface moist.
As tear production becomes less efficient, the eyes may not receive enough moisture throughout the day. This may contribute to aqueous deficient dry eye, where the main issue is insufficient watery tears.
Patients may notice:
Dryness that feels more frequent
Tired eyes during reading or screen use
Grittiness or irritation
Discomfort in dry environments
Increased need for lubricating eye drops
Blurred vision that comes and goes
Reduced tear production may become more noticeable during activities that demand long visual focus, such as reading, computer work, or driving.
How Ageing Affects the Eyelid Oil Glands
Dry eye disease in older adults is not always caused by reduced tear production alone. The meibomian glands also play an important role.
These glands sit along the eyelids and produce the oil that forms the outer lipid layer of the tear film. When they become blocked, inflamed, or less efficient, tears may evaporate too quickly, even if tear production is normal.
This is known as meibomian gland dysfunction, or MGD, which is a major contributor to evaporative dry eye.
Tear Production vs Tear Evaporation With Age
Age-related dry eye may involve reduced tear production, increased tear evaporation, or both.
Age-Related Change | What Happens | What Patients May Notice |
Reduced tear production | The eyes produce less watery tear fluid | Persistent dryness, tired eyes, grittiness |
Increased tear evaporation | Tears dry out too quickly due to unstqable oil layer | Burning, watery eyes, sensitivity to wind or air-conditioning |
Tear film instability | Tears do not spread evenly across the eye surface | Blurred or fluctuating vision |
Eyelid gland changes | Meibomian glands may become blocked or less effective | Eyelid irritation, late-day symptoms |
Ocular surface sensitivity | The eye surface may become more reactive | Irritation, discomfort, light sensitivity |
Hormonal Changes and Dry Eye Disease
Hormonal changes can influence the risk of dry eye disease, especially in women as they get older. These changes may affect tear production, tear film stability, ocular surface inflammation, and meibomian gland function.
Symptoms may include:
Persistent dryness
Burning or stinging
Contact lens discomfort
Eye fatigue
Fluctuating vision
Increased sensitivity to dry environments
Hormonal influence is usually one part of the picture, and other factors such as screen use, medications, eyelid health, and general health may also contribute.
Medication Use in Older Adults
Many older adults take medication for long-term health conditions, and some medicines may contribute to dry eye symptoms by reducing tear production or affecting tear film quality.
Patients should not stop prescribed medication on their own. If symptoms appear after starting a medicine, it may be helpful to discuss this with the prescribing doctor or an eye care professional.
Why Older Adults May Notice More Screen-Related Dry Eye
Screen use is not limited to younger adults. Many older adults use phones, computers, tablets, and televisions daily. During screen use, blinking usually becomes less frequent. Incomplete blinking may also occur, meaning the tear film is not spread fully across the eye surface.
For older adults whose tear film is already less stable, reduced blinking can make symptoms more noticeable.
Comparison Area | Younger Adults | Older Adults |
Common triggers | Screen use, contact lenses, air-conditioning, lack of sleep | Age-related tear changes, medications, health conditions, eyelid gland dysfunction |
Symptom pattern | Often linked to specific activities | More frequent or recurrent |
Tear production | Usually more stable, unless affected by health or lifestyle factors | May decrease with age |
Meibomian gland function | Can be affected by screen use, contact lens wear, eyelid hygiene | May decline with age and inflammation |
Management focus | Reducing triggers and improving habits | Supporting tear film stability and addressing multiple contributing factors |
How Age-Related Dry Eye May Be Managed
Management depends on the cause and severity of symptoms. In older adults, dry eye management may need to address tear production, tear evaporation, eyelid health, medications, and environmental triggers.
Common approaches may include:
Lubricating Eye Drops
Artificial tears may help support tear film comfort. Patients who use drops frequently may be advised to consider preservative-free options.
Eyelid Care and Warm Compresses
If meibomian gland dysfunction is involved, eyelid hygiene and warm compresses may help support oil gland function and reduce tear evaporation.
Environmental Adjustments
Avoiding direct air-conditioning, fan exposure, smoke, and dry airflow may reduce tear film stress.
Screen Habit Changes
Regular breaks,consciously blinking and adjusting screen position may help reduce screen-related symptoms.
Medical Review When Relevant
If medications or health conditions may be contributing, a coordinated review with the relevant healthcare provider may be useful.
Conclusion
Dry eye disease becomes more common with age because ageing affects tear production, tear quality, eyelid function, and overall tear film stability. These changes can make the eyes more vulnerable to irritation, fluctuating vision, and discomfort over time.
Understanding how ageing influences the ocular surface helps support earlier recognition and more effective long-term management of dry eye disease.
Patients experiencing persistent dry eye symptoms or age-related changes in eye comfort should undergo a comprehensive eye assessment with an ophthalmologist. Dr. Paul Lim Chern Pin, Consultant Ophthalmologist, evaluates important factors such as tear production, tear film stability, meibomian gland function, ocular surface health, eyelid condition, and other contributing factors to determine the underlying cause of dry eye disease. Based on the findings, he provides personalised management recommendations to help improve long-term eye comfort, maintain ocular surface health, and support visual quality.
