If your eyes feel persistently dry, gritty, or irritated, you are not alone. Dry eye disease is one of the most common eye complaints seen in eye care, affecting adults of all ages, though it becomes more common over time. Despite how widespread it is, it is frequently misunderstood and often goes undiagnosed for years.
Here is what dry eye disease actually is, why it happens, what it feels like, and when it is time to stop managing it on your own and see a professional.
What Is Dry Eye Disease?
Dry eye disease occurs when your eyes are not producing enough tears, or when the tears they produce evaporate too quickly to keep the eye surface properly lubricated. Your tear film is more complex than it sounds. It is made up of three layers: an oily outer layer that prevents evaporation, a watery middle layer that provides moisture and nutrients, and a mucus inner layer that helps the tears spread evenly across the eye.
When any of these layers is out of balance, the result is an unstable tear film that leaves the surface of your eye exposed and irritated. Over time, this can affect not just your comfort but also your vision quality.
Common Symptoms of Dry Eye
Dry eye does not always feel the way you might expect. The symptoms can be subtle and are sometimes mistaken for allergies, fatigue, or just “getting older.” Common signs include:
- A dry, scratchy, or gritty sensation, as if something is in your eye
- Burning or stinging, especially in air-conditioned or heated environments
- Redness or general eye irritation
- Blurry vision that comes and goes, often clearing after blinking
- Increased sensitivity to light
- Difficulty wearing contact lenses comfortably
- Eye fatigue, particularly during reading or screen use
One symptom that surprises many people: watery eyes. When your eyes are chronically dry, they can trigger a reflex response that floods the eye with tears. These reflex tears do not have the same balanced composition as your normal tear film, so they do not actually solve the underlying problem, and the watery eyes return quickly.
What Causes Dry Eye Syndrome?
Dry eye has many potential causes, and for most people it is a combination of factors rather than a single root cause.
Age. Tear production naturally decreases as we get older. Dry eye is more common in adults over 50, and particularly in women after menopause due to hormonal changes.
Screen use. Extended screen time reduces blink rate significantly, which allows tears to evaporate faster than they are replenished. This is one reason dry eye has become increasingly common across all age groups.
Environment. Dry climates, air conditioning, heating, wind, and smoke can all accelerate tear evaporation. Seasonal changes, particularly cold or windy weather, can be harder on eyes that are already prone to dryness.
Contact lens wear. Contact lenses can disrupt the tear film and increase tear evaporation from the eye surface, contributing to dryness and discomfort over the course of the day.
Medications. A number of common medications list dry eye as a side effect, including antihistamines, decongestants, antidepressants, blood pressure medications, and hormonal contraceptives.
Health conditions. Autoimmune conditions like Sjogren’s syndrome, rheumatoid arthritis, and lupus are associated with dry eye. Thyroid disorders and diabetes can also contribute.
Eyelid issues. Meibomian gland dysfunction (MGD) is one of the most common causes of dry eye disease. The meibomian glands line the eyelids and produce the oily layer of the tear film. When these glands become blocked or dysfunctional, the oily layer breaks down and tears evaporate too quickly.
How Is Dry Eye Diagnosed?
A comprehensive eye exam is the right starting point. Your eye doctor can evaluate your tear film, measure tear production, and assess the health of your eyelid glands and eye surface. In some cases, additional testing is done to measure the quality and stability of your tears.
It is worth being thorough here because the underlying cause of your dry eye affects which treatment will work best for you.
Treatment Options
Dry eye is a manageable condition, and most people find significant relief with the right approach. Common treatments include:
Artificial tears. Over-the-counter lubricating eye drops are often the first line of relief. Preservative-free formulas are generally better tolerated for frequent use.
Warm compresses and lid hygiene. For dry eye related to meibomian gland dysfunction, regular warm compresses and gentle eyelid cleaning can help restore normal oil production.
Prescription eye drops. For moderate to severe dry eye, prescription anti-inflammatory drops or medications that stimulate tear production may be recommended.
Lifestyle adjustments. Staying well hydrated and building in regular screen breaks can support overall eye comfort. Some patients find omega-3 supplements helpful for tear film health, though research results are mixed; it is worth discussing with your eye doctor before adding them to your routine.
In-office treatments. Depending on the cause and severity, your eye doctor may recommend in-office procedures to clear blocked meibomian glands or reduce inflammation.
When to See an Eye Doctor
Over-the-counter drops can provide temporary relief, but if you are using them multiple times a day and still not getting comfortable, it is time to have your eyes evaluated. Untreated dry eye can irritate and damage the eye’s surface over time, and some underlying causes benefit from treatment beyond what drops can provide.
You should also see an eye doctor if your symptoms are affecting your ability to work, drive, or wear contacts comfortably, or if you have sudden changes in vision alongside your dryness symptoms.

Book An AppointmentFrequently Asked Questions
Is dry eye syndrome a permanent condition? For some people, dry eye is chronic and requires ongoing management. For others, it is temporary and resolves once the underlying cause is addressed. An eye doctor can help determine what is driving your symptoms and whether long-term management is needed.
Can dry eye affect my vision? Yes. An unstable tear film can cause blurry or fluctuating vision, particularly during extended reading or screen use. In most cases, this improves after blinking or using lubricating drops, but persistent dry eye left untreated can cause surface damage that affects vision more significantly over time.
Are artificial tears safe to use every day? Preservative-free artificial tears are generally safe for daily use and are the better choice if you are using drops frequently. Drops that contain preservatives can cause irritation with heavy use, though they are still appropriate for occasional relief.
Can dry eye be caused by allergies? Allergies and dry eye share many of the same symptoms and often occur together, which can make it difficult to tell them apart. An eye doctor can help distinguish between the two and recommend the right treatment for each.
Why do my eyes water if I have dry eye? Watery eyes are a common and counterintuitive symptom of dry eye. When the eye surface is chronically irritated, it triggers a reflex response that produces a flood of tears. These reflex tears are not the same as your normal tear film, so they do not solve the problem, and the irritation quickly returns.
Does diet affect dry eye? Some patients find omega-3 supplements helpful for tear film health, but research results are mixed and they are not effective for everyone. A diet that includes fatty fish, flaxseed, or walnuts is a reasonable general approach, and staying well hydrated supports overall eye comfort. Talk to your eye doctor before starting supplements.
