Dry Eye
What Is Dry Eye?
Dry eye comes in two main types. Aqueous-deficient dry eye means your tear glands do not make enough of the watery layer of your tears. Evaporative dry eye happens when the oily layer of your tears is not working properly, causing tears to dry up too fast.
Many people have a mix of both types. Understanding which type you have helps us choose the best treatment for your needs.
Your tears are made of three layers that work together. The oily outer layer prevents evaporation, the watery middle layer provides moisture and nutrients, and the mucus inner layer helps tears stick to your eye surface.
When any of these layers is out of balance, your eyes can feel dry, gritty, or uncomfortable. Healthy tears also wash away debris and protect against infection.
Everyone experiences dry eyes once in a while, especially in windy weather or after long reading sessions. Chronic dry eye is different because symptoms happen regularly and last for weeks or months.
If you notice persistent discomfort, burning, or redness, we may recommend an evaluation. Chronic dry eye can lead to complications if left untreated, so early care is important.
Signs and Symptoms of Dry Eye
Dry eye often starts with mild symptoms that come and go. You might notice a scratchy or sandy feeling in your eyes, like something is stuck there even when nothing is.
- Stinging or burning sensation
- Redness of the white part of your eyes
- Sensitivity to light or wind
- Heavy or tired eyelids
It might seem strange, but watery eyes can actually be a sign of dry eye. When your eye surface becomes irritated from dryness, your tear glands respond by producing extra tears to try to fix the problem.
These reflex tears are mostly water and do not have the right balance of oils and mucus. They wash away quickly and do not keep your eyes properly lubricated, leaving you stuck in a cycle of dryness and excess tearing.
Dry eye can make everyday tasks harder. Your vision might become blurry, especially when you read, drive, or use a computer for long periods. Some people find their eyes feel worse at the end of the day.
Many patients tell us dry eye interferes with their favorite activities. Wearing contact lenses may become uncomfortable, and being outdoors or in air-conditioned spaces can worsen symptoms.
Most dry eye symptoms are not emergencies, but certain warning signs need immediate attention. Seek prompt care if you notice any of these signs:
- Sudden vision loss or significant new vision change
- Severe eye pain, especially with headache or nausea
- Thick, colored discharge from your eye
- Contact lens wearer with new redness, pain, or light sensitivity
- Chemical splash or foreign material in your eye
- Sudden severe light sensitivity that will not go away
- Recent eye surgery with worsening pain, redness, or vision changes
If you have redness that keeps getting worse, new floaters or flashes of light, feel like something is seriously wrong, or have eye symptoms after an injury, do not wait for a regular appointment. Prompt evaluation can prevent lasting damage.
What Causes and Increases Your Risk for Dry Eye
Dry eye becomes more common as you get older. After age 50, tear production naturally decreases for many people. Women are at higher risk than men, especially during pregnancy, while using birth control pills, and after menopause.
Hormonal changes can affect the glands that produce tears and the oils that keep tears from evaporating. This is one reason we see dry eye more often in women over 40.
Certain health conditions can interfere with tear production or tear quality. Autoimmune diseases like rheumatoid arthritis, lupus, and Sjögren syndrome often cause dry eye as one of their symptoms.
- Diabetes and thyroid disorders
- Rosacea and other skin conditions
- Vitamin A deficiency
- Conditions that affect your ability to blink normally
Many common medications can dry out your eyes as a side effect. Antihistamines, decongestants, and blood pressure medications are frequent culprits. Antidepressants and anti-anxiety drugs can also decrease tear production.
If you take medications regularly and develop dry eye symptoms, let us know. We can help you weigh the benefits of your medications against your eye comfort and may suggest ways to manage both.
Your surroundings play a big role in dry eye symptoms. Dry climates, wind, smoke, and air conditioning can all increase tear evaporation. People who live at high altitudes or in arid regions often experience more dryness.
Activities that reduce your blink rate can also contribute. When you focus intently on a task, you tend to blink less often, which means your tears are not spread evenly across your eye surface.
Spending hours looking at screens can worsen dry eye. When you stare at a computer, tablet, or phone, your blink rate can drop by more than half. Incomplete blinks also become more common, so your tear film does not get refreshed properly.
Digital eye strain combines with dry eye to create discomfort, fatigue, and blurred vision. Taking regular breaks and being mindful of blinking can help protect your eyes during screen use.
How We Diagnose Dry Eye
Your dry eye evaluation starts with a conversation about your symptoms, medical history, and daily habits. We will ask about when your eyes feel worst, what makes them better or worse, and any medications you take.
Next, we will examine your eyes using special instruments. We look at your eyelids, lashes, and the surface of your eyes to check for signs of inflammation, damage, or blocked oil glands.
We also rule out other conditions that can mimic or overlap with dry eye, such as allergies, infection, medication side effects including from glaucoma drops, eyelid mites or blepharitis, and exposure problems. Identifying the correct cause ensures you get the right treatment.
We have several ways to measure the quantity and quality of your tears. One common test involves placing a small strip of paper under your lower eyelid to see how much moisture it absorbs over five minutes.
- Tear break-up time test to see how quickly tears evaporate
- Osmolarity test to measure the saltiness of your tears
- Imaging to look at the lipid layer on your tear film
Chronic dry eye can cause tiny scratches or rough patches on your cornea and conjunctiva. We may use special dyes that temporarily stain your eye surface to make any damage visible under our examination light.
Finding these changes helps us understand how severe your dry eye is. It also guides our treatment plan and gives us a baseline to track your improvement over time.
After completing your tests, we will determine whether you have aqueous-deficient dry eye, evaporative dry eye, or a combination. We also classify your condition as mild, moderate, or severe.
This information shapes your personalized treatment plan. Mild dry eye might respond well to simple measures, while moderate to severe cases often need a combination of therapies for the best results.
Treatment Options for Dry Eye
For many patients, over-the-counter artificial tears are the first step in managing dry eye. These drops add moisture to your eyes and come in different thicknesses. Preservative-free formulas are better for frequent use.
We may also recommend lubricating gels or ointments for nighttime. These thicker products blur your vision temporarily but provide longer-lasting relief while you sleep.
- Choose preservative-free tears if you need drops frequently, often more than four times daily
- Avoid redness-relieving drops with vasoconstrictors for daily use, as they can worsen dry eye over time
- Lipid-based tears may work better for evaporative dry eye or meibomian gland dysfunction
- Use nighttime gels or ointments for longer-lasting moisture while you sleep
- If you wear contact lenses, use rewetting drops labeled for contacts and follow lens-wear instructions
When dry eye involves inflammation, we may prescribe medicated eye drops. Anti-inflammatory prescription options include cyclosporine formulations and lifitegrast, which work to reduce inflammation and can improve your tear film over time.
These prescription treatments usually take several weeks to show full benefits. You will continue using them regularly to keep inflammation under control and help your eyes produce healthier tears.
In some cases, we may use short-term topical steroid drops for flares or to start therapy. Steroid drops require close supervision because they can raise eye pressure, increase cataract risk, and increase infection risk. We use them carefully and monitor you closely.
If your oil glands are blocked or not working well, we focus on treatments that improve the oily layer of your tears. Warm compresses and gentle eyelid massage can help melt the oils and clear blockages. Lid margin hygiene with commercial lid cleansers helps keep glands clear and reduces irritation.
If you have blepharitis or rosacea contributing to your meibomian gland problem, we may recommend specific treatments for those conditions. In selected cases, we may prescribe oral antibiotics such as doxycycline to reduce inflammation. Consistent home maintenance care is usually needed long-term to keep your glands working well.
- In-office thermal pulsation devices that heat and massage your eyelids
- Intense pulsed light therapy to reduce inflammation around the glands
- Manual expression of the glands during an office visit
Punctal plugs are tiny devices we insert into your tear drain openings. By slowing drainage, they help your natural tears stay on your eye surface longer. These plugs can be temporary or long-lasting, depending on your needs.
Possible side effects include watering or overflow tearing, irritation or a foreign body sensation, plugs falling out, and rarely infection or inflammation of the tear duct. Some patients need treatment of significant surface inflammation before we place plugs. We will monitor you after placement to ensure the plugs are working well.
Thermal treatments use controlled heat to stimulate oil gland function and reduce inflammation. These procedures may require repeat sessions, and outcomes vary from person to person. We may recommend these treatments if other options have not provided enough relief.
Sometimes the best way to improve dry eye is to address the root cause. If an autoimmune disease or skin condition is contributing to your symptoms, we may coordinate care with your other doctors.
Managing diabetes, adjusting medications, or treating eyelid inflammation can all lead to significant improvement. We take a whole-person approach to help you feel better.
Severe or stubborn dry eye may require multiple treatments at once. We might combine prescription drops with in-office procedures, supplements, and lifestyle changes for the best outcome.
Advanced therapies such as autologous serum eye drops, made from your own blood, may be considered in specific cases when standard treatments are not enough. Other options for selected severe cases include scleral contact lenses that protect the eye surface, moisture chamber eyewear, permanent punctal closure for severe tear deficiency, and specialized membrane treatments for significant surface damage.
Our goal is always to restore your comfort and protect your vision.
Taking Care of Your Eyes at Home
Small changes to your routine can make a big difference in managing dry eye. Staying hydrated by drinking plenty of water supports overall health and may help some people. Wearing wraparound sunglasses outdoors shields your eyes from wind and sun.
- Remember to blink fully and often, especially during concentrated tasks
- Position air vents away from your face in your car and home
- Use a humidifier to add moisture to dry indoor air
- Avoid rubbing your eyes, which can worsen irritation
Keeping your eyelids clean helps prevent oil gland blockages and reduces inflammation. We may recommend using a gentle cleanser designed for eyelids. If advised, diluted baby shampoo can be an alternative, though eyelid-specific cleansers are preferred to reduce irritation risk.
Warm compresses are often helpful for evaporative dry eye. The compress should be comfortably warm, not hot, and maintained for eight to ten minutes. Reheat the compress as needed to keep it warm throughout the treatment. If instructed, follow with gentle lid massage to help express the oils. Stop if you develop skin irritation.
Simple changes to where you spend your time can ease dry eye symptoms. Lower the temperature on your heating system to reduce air dryness, and place your computer screen below eye level so your eyes do not open as wide.
If you work in a dry or dusty environment, take breaks to rest your eyes. Consider using desk humidifiers or protective eyewear to create a more comfortable space for your eyes.
What you eat can influence your tear quality. Omega-3 fatty acids found in fish like salmon and sardines may help reduce eye inflammation and support healthy oil glands in some patients, though the benefit is not universal. If you consider omega-3 supplements, discuss dosing and possible interactions with us, especially if you take blood thinners, as omega-3s can increase bleeding risk and may cause digestive upset. Supplement quality also varies, so prioritize dietary sources when possible.
A balanced diet supports overall eye health. Vitamin A is important for tear production and eye surface health, especially if you have deficiency risk. If you think your diet might be lacking, talk with us about whether supplements are right for you.
The 20-20-20 rule is a simple way to reduce digital eye strain. Every 20 minutes, look at something 20 feet away for at least 20 seconds. This gives your eyes a break and encourages natural blinking.
Adjust your screen brightness to match your surroundings, and increase text size if you find yourself squinting. Keeping your screen clean and reducing glare with an anti-reflective filter can also help.
We will create a follow-up schedule based on your treatment plan. Some patients need to return in a few weeks to check progress, while others come back every few months once their symptoms are stable.
Do not wait for your scheduled visit if your symptoms suddenly worsen or if you develop new problems. Regular monitoring helps us adjust your treatment and ensure the best possible outcome.
Frequently Asked Questions
Most cases of dry eye are chronic conditions that we manage rather than cure. With the right combination of treatments and lifestyle changes, many patients achieve lasting relief, reduce flares, and improve long-term control. Staying consistent with your care plan gives you the best chance of long-term comfort.
The timeline varies depending on what treatments you use. Artificial tears provide immediate but temporary relief, while prescription anti-inflammatory drops often take four to six weeks to show their full effect. In-office procedures may offer quicker improvement, and some patients notice a difference within days.
Dry eye and eye allergies share some symptoms like redness and irritation, but they are different conditions. Allergies typically cause itching and watery discharge, while dry eye usually involves burning and a gritty sensation. You can have both at the same time, and we will examine your eyes to determine the right diagnosis.
Contact lenses can contribute to dry eye, especially if worn for long hours or not cared for properly. Lenses absorb some of your tear film and can reduce oxygen flow to your cornea. If you have dry eye, we may suggest daily disposable lenses, reducing wear time, or switching to different lens materials.
Some patients need ongoing treatment to keep symptoms under control, while others improve enough to reduce or stop therapy after a period of care. Your individual outlook depends on the cause and severity of your dry eye. We will work with you to find the least burdensome approach that keeps your eyes comfortable.
Preservative-free artificial tears are safe for frequent daily use and are often the foundation of dry eye care. Drops with preservatives can irritate your eyes if you need them frequently, often more than four times a day, depending on the preservative type and your eye sensitivity. Avoid redness-relieving drops for daily use, as they can make dry eye worse over time.
