Dry Eye
What Causes Dry Eye and Who Is at Risk
Your tears are made of three layers that work together to keep your eyes moist and clear. The outer oily layer prevents evaporation, the middle watery layer delivers nutrients and oxygen, and the inner mucus layer helps tears spread evenly across your eye. When any of these layers is out of balance, dry eye can develop.
Problems can arise if your glands do not produce enough tears or if your tears evaporate too quickly. Both issues leave your eye surface without the protection it needs.
Several health conditions can interfere with healthy tear production. Autoimmune diseases such as rheumatoid arthritis, lupus, and Sjogren syndrome often affect the glands that make tears. Diabetes can damage nerves that control tear production, and thyroid eye disease may change the way your eyelids close or how your glands work. Neurologic conditions affecting blinking or eyelid closure, such as facial nerve palsy or Parkinson disease, can also contribute to dry eye.
Skin conditions around the eyelids, including rosacea and blepharitis, can block the oil glands in your lids and lead to faster tear evaporation. Eyelid malposition or incomplete eyelid closure can prevent proper tear distribution and expose the eye surface to drying.
Many common medications reduce tear production as a side effect. If you take any of the following, you may be at higher risk for dry eye:
- Antihistamines and decongestants for allergies or colds
- Blood pressure medications, especially diuretics
- Antidepressants and anti-anxiety drugs
- Hormone replacement therapy or birth control pills
- Acne treatments, particularly isotretinoin
- Anticholinergic medications used for various conditions
- Some glaucoma eye drops with long-term use
- Medications for Parkinson disease
Your surroundings can have a big impact on your tear film. Dry climates, high altitudes, air conditioning, and heating all lower humidity and speed up tear evaporation. Wind and smoke also irritate your eyes and strip away moisture. Air leaks from CPAP masks during sleep can dry the eye surface overnight.
Extended screen time reduces how often you blink, which means tears do not get refreshed as they should. Reduced or incomplete blinking for any reason can worsen dry eye. Jobs that require intense focus or contact lens wear can make the problem worse.
Dry eye becomes more common as you get older because tear production naturally slows down. Women are affected more often than men, especially during pregnancy, menopause, or while using hormonal birth control. These hormonal shifts can change both the quantity and quality of your tears.
People over 50 are at the highest risk, but younger adults who spend many hours on digital devices also experience dry eye regularly.
Recognizing the Signs and Symptoms of Dry Eye
Dry eye can feel different from person to person, but most patients describe a gritty or sandy sensation, as if something is in the eye. Other typical symptoms include:
- Burning or stinging that gets worse as the day goes on
- Redness and irritation, especially in the corners
- Blurred vision that clears when you blink
- Sensitivity to light or difficulty wearing contact lenses
- Eye fatigue after reading or computer work
It may seem strange, but many people with dry eye notice excessive tearing. This happens because dryness and irritation trigger your eyes to produce extra tears as a reflex. Unfortunately, these reflex tears are mostly water and lack the oils and mucus needed to stay on the eye surface, so they overflow down your cheeks without actually relieving the dryness.
This watery response is a sign that your tear film is unstable, not that your eyes are well lubricated.
Most dry eye is uncomfortable but not an emergency. However, certain symptoms require same-day evaluation, including:
- Contact lens wearers with pain, redness, light sensitivity, discharge, or blurred vision
- Sudden severe pain or major increase in redness
- Thick discharge or sudden drop in vision
- Chemical exposure to the eye or eye injury with persistent pain
- New severe light sensitivity or inability to keep the eye open
If you think you may have an eye emergency, seek urgent or emergency care immediately. These symptoms could indicate an infection, corneal abrasion, or another urgent condition that needs immediate attention.
If over-the-counter remedies do not help within a few days or your symptoms keep getting worse, we may recommend a comprehensive eye exam to rule out more serious issues.
How We Diagnose Dry Eye in Our Office
Diagnosis starts with a conversation about your symptoms, when they occur, and what makes them better or worse. We will ask about your overall health, current medications, work environment, and daily habits. This helps us understand whether your dry eye is caused by tear production problems, tear quality issues, or a combination of both.
Sharing details about screen time, contact lens use, and any autoimmune conditions gives us important clues for tailoring your treatment plan.
Using a special microscope called a slit lamp, your eye doctor examines the front surface of your eyes under magnification. We look for redness, swelling, and signs of inflammation on the conjunctiva and cornea. We also check the edges of your eyelids for blocked oil glands or crusting that might contribute to tear film instability.
This exam helps us see any damage that dryness may have caused and guides our choice of treatments.
We may perform a test that measures how much tears you produce, often by placing a small strip of paper at the edge of your lower eyelid for a few minutes. We also evaluate how long your tear film stays stable on the eye surface before breaking up. These tests are brief, but some can cause temporary irritation or watering. They show whether you are making enough tears and if those tears are healthy enough to protect your eyes.
In some cases, we use special dyes that highlight dry spots or areas of damage on the cornea.
The meibomian glands in your eyelids produce the oily layer of your tears. When these glands get blocked or stop working, tears evaporate too fast. We may use imaging technology to see the structure of these glands and determine whether they are functioning properly.
If gland dysfunction is present, we may recommend targeted therapies to restore oil flow and improve tear quality.
Some practices use additional testing to better understand the type and severity of your dry eye. These may include measuring tear osmolarity to assess how concentrated your tears are, testing for inflammatory markers on the eye surface, or evaluating the quality of the oils produced by your meibomian glands. These adjunct tests can help guide a more tailored treatment plan.
Not all tests are available or necessary in every office or for every patient. We will discuss which tests are most helpful for your specific situation.
Treatment Options for Mild to Moderate Dry Eye
For mild to moderate dry eye, over-the-counter artificial tears are often the first step. These drops add moisture to your eyes and can be used several times a day. Preservative-free formulas are best if you need drops more than four times daily, since preservatives can irritate your eyes over time.
If you need longer-lasting relief, we may recommend gel drops or ointments, especially at bedtime.
When dry eye is driven by inflammation, artificial tears alone may not be enough. We may prescribe anti-inflammatory eye drops that help your eyes produce healthier tears and reduce surface damage. These medications typically take a few weeks to show full benefit, so consistent use is important.
Commonly prescribed options include cyclosporine and lifitegrast, both of which target the underlying immune response that worsens dry eye. Cyclosporine can cause burning on instillation, and lifitegrast may cause taste disturbance. Onset of benefit often takes weeks to months.
In some cases, we may use a short course of topical steroid drops to reduce inflammation more quickly, especially when starting other therapies. Steroids require careful monitoring for side effects such as increased eye pressure or cataract risk. Other options include tear-stimulating nasal spray or prescription drops designed specifically for evaporative dry eye, depending on your individual needs.
If your oil glands are blocked, we may recommend in-office treatments to clear them and restore healthy tear film. Thermal pulsation devices apply gentle heat and massage to your eyelids, melting blockages and encouraging oil flow. Intense pulsed light therapy may be considered in specific cases to reduce inflammation around the glands.
These procedures may provide significant relief, especially when combined with daily eyelid hygiene at home.
Punctal plugs are tiny devices inserted into the tear drainage ducts in your eyelids. By blocking these ducts, the plugs keep your natural tears on the eye surface longer. This option works well if you do not produce enough tears and need to make the most of what you have. Plugs are often considered after addressing ocular surface inflammation or meibomian gland dysfunction, since they may not be ideal for uncontrolled inflammatory dry eye.
The procedure is quick and typically well tolerated, and the plugs can be temporary or long-lasting depending on your needs. Potential side effects include excessive tearing, irritation or foreign body sensation, plug extrusion, and rarely infection or inflammation of the tear duct.
Comprehensive and Advanced Treatment Strategies
If a medical condition or medication is causing your dry eye, addressing the root problem is essential for long-term improvement. We may work with your primary care doctor to adjust medications that dry out your eyes or to manage autoimmune diseases more effectively. Treating eyelid conditions such as blepharitis or rosacea can also make a big difference.
Sometimes a small change in your routine or prescriptions can bring significant relief.
Omega-3 fatty acids found in fish oil and flaxseed may help improve the quality of the oily layer in your tears. Some studies suggest that regular supplementation can reduce dry eye symptoms, especially when combined with other treatments, though results have been variable. We may recommend a high-quality omega-3 supplement if you have meibomian gland dysfunction.
Always talk to your eye doctor before starting any supplement to make sure it fits your overall care plan. Omega-3 supplements can interact with blood thinners or other medications, may increase bleeding risk around surgery, and can cause digestive side effects in some people.
For moderate to severe dry eye that does not respond to standard treatments, we may consider advanced options. Autologous serum tears are custom-made eye drops created from your own blood, providing growth factors and nutrients that support healing of the ocular surface. Platelet-rich plasma drops work similarly and may be used where available.
Scleral lenses are large, specially designed contact lenses that vault over the cornea and hold a reservoir of fluid to protect and lubricate the eye surface throughout the day. Moisture chamber goggles or nighttime strategies such as ointments or eyelid taping may be recommended if you have incomplete eyelid closure or exposure during sleep. We will discuss these options if they become appropriate for your care.
Daily Habits and Self-Care Steps to Manage Dry Eye
Staring at screens reduces your blink rate, which means your tear film does not refresh as often as it should. Make a conscious effort to blink fully and regularly, especially during computer work, reading, or gaming. Follow the 20-20-20 rule by taking a 20-second break every 20 minutes to look at something 20 feet away.
Positioning your screen slightly below eye level can also help, since looking down encourages more complete blinking.
Indoor heating and air conditioning remove moisture from the air, which speeds up tear evaporation. Running a humidifier in your bedroom or workspace adds moisture back and can ease dry eye symptoms. Aim for humidity levels between 30 and 50 percent.
Avoid placing fans or vents so they blow directly on your face, and consider using air filters to reduce dust and allergens that can irritate your eyes.
Keeping your eyelids clean helps prevent blockages in the oil glands and reduces inflammation. Gently wash your eyelid margins with a warm, damp cloth or a lid scrub product recommended by your eye doctor. Doing this once or twice a day can make a noticeable difference.
Applying a warm compress to closed eyelids for 5 to 10 minutes softens oil in the glands and encourages healthy tear production. This simple routine is especially helpful if you have meibomian gland dysfunction.
Outdoor conditions such as wind, sun, and dry air can make dry eye worse. Wraparound sunglasses or moisture-chamber glasses shield your eyes from these irritants and slow tear evaporation. Wearing protective eyewear is especially important if you spend time outdoors in windy or arid climates.
Even on cloudy days, glasses can reduce exposure to airborne particles that irritate already sensitive eyes.
Drinking plenty of water supports your overall health and may help your body produce adequate tears. Dehydration can worsen dry eye symptoms, so stay adequately hydrated throughout the day. Eating a balanced diet rich in omega-3 fatty acids, leafy greens, and colorful vegetables may also support eye health.
Limiting caffeine and alcohol can help, since both can contribute to dehydration.
What to Expect After Treatment and When to Follow Up
Relief from dry eye varies depending on the cause and the treatments you use. Over-the-counter artificial tears may provide immediate comfort, but prescription medications and in-office procedures often take several weeks to show their full effect. Some patients notice gradual improvement over one to three months as inflammation decreases and tear production stabilizes.
Patience and consistency with your treatment plan are key to achieving lasting relief.
Dry eye is often a chronic condition that requires long-term management rather than a one-time cure. Regular follow-up visits allow your eye doctor to monitor your progress, adjust treatments as needed, and catch any complications early. Stopping treatment too soon can lead to a return of symptoms or even worsening of the condition.
We will work with you to create a sustainable care routine that fits your lifestyle and keeps your eyes comfortable.
If your symptoms are not improving after a few weeks, or if they get worse despite treatment, let us know right away. New or increasing pain, vision changes, or discharge could mean your dry eye has progressed or that another problem has developed. We may recommend different medications, additional tests, or a referral to a specialist if needed.
Open communication helps us fine-tune your care and achieve the best possible outcome.
Frequently Asked Questions
Some cases of dry eye improve once you remove the trigger, such as changing a medication or moving to a more humid climate. However, many people experience chronic dry eye that requires ongoing management and will not fully resolve without treatment. Your eye doctor can help you understand your specific situation and develop a plan to keep symptoms under control.
Preservative-free artificial tears are safe for daily use and can be applied as directed on the label and by your clinician. Drops with preservatives should generally be limited to four times a day, since regular exposure to preservatives can irritate your eyes and worsen dryness. Avoid frequent use of redness reliever drops for chronic dry eye symptoms, as they can worsen the problem over time.
If you wear contact lenses, verify that the drops are compatible with your lenses and follow instructions about whether to remove lenses before instilling drops. Always check the label and ask our team if you are unsure which product is right for you.
Contact lenses can reduce the amount of oxygen reaching your cornea and may absorb tears from your eye surface, both of which can worsen dry eye symptoms. If you wear contacts and have dry eye, we may recommend switching to daily disposable lenses, reducing wear time, or choosing lenses designed for sensitive eyes. In some cases, glasses may be a better option until your dry eye is better controlled.
Dry eye and eye allergies can cause similar symptoms such as redness, irritation, and watering, but they are different conditions with different causes. Allergies are triggered by an immune response to pollen, pet dander, or other allergens, while dry eye results from tear film problems. It is possible to have both at the same time, which is why a thorough exam is important to determine the right treatment.
Untreated dry eye can lead to damage on the surface of your cornea, including scarring and ulcers in severe cases. This damage may cause lasting vision problems if not addressed. Early diagnosis and consistent treatment help prevent complications and protect your long-term eye health, so it is important not to ignore persistent symptoms.
