How Do I Get Rid of Dry Eyes? Causes & Treatments

Getting rid of dry eyes depends on what is causing them, and for most people that means tackling everyday factors like screen habits, eyelid oil-gland health, and the right kind of eye drops before considering anything more aggressive. Dry eye is not a single problem with a single fix. The condition involves either too little tear production, too-fast tear evaporation, or, frequently, a combination of both. That distinction matters because the treatment that works for one type can be useless for the other, and misidentifying your situation is one of the most common reasons people cycle through bottles of artificial tears without relief.

Why Your Eyes Feel Dry in the First Place

Your tear film is not just water. It is a layered structure with an oily outer layer produced by meibomian glands in your eyelids, a watery middle layer from the lacrimal glands, and a mucus layer produced by goblet cells on the eye’s surface. Each layer has a job: the oil slows evaporation, the water delivers oxygen and nutrients, and the mucus helps tears spread evenly across the cornea.¹ When any layer falls short, the remaining tears become saltier than they should be, and that elevated salt concentration triggers a chain of inflammation. The inflamed surface kills off more goblet cells, which worsens the mucus layer, which destabilizes the tear film further.² This self-reinforcing loop is why dry eye often gets worse over time if left alone.

Clinicians divide dry eye into aqueous-deficient (not enough water) and evaporative (tears evaporate too fast), though in practice most cases involve some mix of both.³ The overlap can be confusing even for doctors, because a thin tear layer from low water production also shortens the time tears stay stable on the eye, mimicking what happens when the oil layer is deficient.³ Still, it is worth understanding the broad categories because the treatments differ significantly.

The Most Common Culprit You Have Never Heard Of

Evaporative dry eye driven by meibomian gland dysfunction accounts for the majority of dry eye cases, and it is wildly underdiagnosed. The meibomian glands line the edges of your upper and lower eyelids. When they work properly, they secrete a thin oil (meibum) every time you blink, creating the barrier that keeps your tears from evaporating too quickly. When these glands become blocked, inflamed, or damaged, the oil changes in quality and quantity.⁴ The result is faster tear evaporation, higher tear saltiness, more surface staining, more inflammation, and that gritty, burning feeling.⁵

This matters for treatment because if blocked oil glands are the root issue, simply adding more water-based artificial tears will only provide temporary comfort. You need to address the oil layer, which means different interventions entirely.

Screens, Blinking, and the Modern Dry Eye Epidemic

If your dry eyes are worst during or after long stretches at a computer, phone, or tablet, you are not imagining it. Studies consistently show that your blink rate drops when you are watching a screen. In people with normal tear function, blinking during video viewing was significantly lower than during conversation.⁶ Fewer blinks means less oil is squeezed out of the meibomian glands and less tear film is refreshed across the eye. Over hours, the cumulative effect is substantial.

The practical fix is annoyingly simple but genuinely helpful: follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), consciously blink a few times when you remember, and position your screen slightly below eye level so your lids cover more of the eye surface. These are free, immediate interventions that reduce symptoms for most screen-related dry eye sufferers.

Environmental and Indoor Factors

Air quality, humidity, and temperature all influence dry eye symptoms in ways that are measurable and sometimes surprising. Outdoor air pollutants like fine particulate matter, ozone, and nitrogen dioxide have all been linked to worsening dry eye indicators, including higher tear saltiness, lower tear production, and more surface damage.⁷ Higher temperatures and higher humidity were each associated with lower symptom scores in that same study, which makes intuitive sense: warm, moist air slows tear evaporation.

Indoors, however, the relationship gets more complicated. While low humidity clearly speeds up tear evaporation, very high indoor humidity can keep irritating particles airborne longer and promote mold and other bioaerosols that inflame the eye surface.⁸ The practical takeaway is that moderate humidity (roughly 40 to 60 percent) in your home and office is probably the sweet spot. Air purifiers and humidifiers both have some evidence behind them as individual-level strategies for people whose dry eye worsens with environmental exposure.⁹

When Dry Eyes Signal Something Bigger

Sometimes dry eyes are not just dry eyes. Sjögren’s syndrome is a chronic autoimmune disease in which the immune system attacks the glands that produce tears and saliva, causing persistent dryness of the eyes and mouth.¹⁰ It can occur on its own or alongside other autoimmune conditions like rheumatoid arthritis or lupus.¹¹ Over time, the lymphocyte-driven inflammation permanently destroys the exocrine glands, making the dryness progressive and irreversible if not managed early.¹²

If your dry eyes came on alongside a persistently dry mouth, joint pain, fatigue, or skin changes, bring those symptoms up with your doctor. Sjögren’s is frequently diagnosed years after symptoms begin, and early treatment can slow gland destruction. Standard dry eye treatments help with comfort, but managing the underlying autoimmune process requires systemic therapy.

Hormonal Shifts

Sex hormones play a real role in tear production. Estrogens and androgens influence all three layers of the tear film, including how much oil the meibomian glands produce.¹³ In postmenopausal women, the hormonal changes compound the effects of aging on the eye surface, though researchers still debate whether it is estrogen decline, androgen decline, or the shift in their ratio that matters most.¹⁴ The practical point is that if your dry eyes coincided with perimenopause or menopause, hormonal changes are likely a contributing factor, and you should expect to need ongoing management rather than a quick fix.

After LASIK or Other Refractive Surgery

Dry eye after LASIK is one of the most common post-surgical complaints, and the mechanism is well understood. The laser flap cuts corneal nerves that normally signal the lacrimal gland to produce tears. These nerves regenerate slowly: corneal nerve structure was still altered six months after surgery in one study,¹⁵ and long-term studies show nerve changes persisting well beyond that window.¹⁶ Newer techniques like SMILE (small-incision lenticule extraction) cause less nerve disruption. One head-to-head comparison found that tear volume dropped by roughly 31 percent after conventional LASIK but not significantly after SMILE, and the impact on corneal nerve density was substantially greater with the flap-based procedure.¹⁷

If you already have dry eye and are considering vision correction surgery, discuss this with your surgeon. Pre-existing dryness is a risk factor for worse post-operative symptoms, and the choice of technique can make a meaningful difference.

First-Line Treatment: Artificial Tears and Lid Hygiene

For most people, the first step is over-the-counter artificial tears. These come in preserved (multi-dose bottles) and preservative-free (single-use vials) formulations. A systematic review found no statistically significant difference in effectiveness between the two.¹⁸ However, a more recent study using corneal imaging found that preservative-free drops led to better corneal healing and greater symptom improvement, particularly with long-term use.¹⁹ The practical advice: if you use drops only a few times a day, either type is fine. If you are reaching for them four or more times daily, switch to preservative-free to avoid the cumulative irritation that preservatives can cause over time.

If your dry eye involves meibomian gland dysfunction, warm compresses are a cheap and effective add-on. Applying gentle heat to closed eyelids for five to ten minutes melts thickened oil trapped in the glands, allowing it to flow onto the tear film and reduce evaporation.²⁰ Follow the warmth with a gentle lid massage or use a commercially available heated eye mask designed to maintain consistent temperature. Consistency matters more than intensity: doing this daily produces better results than doing it aggressively once a week.

Prescription Drops for Moderate to Severe Dry Eye

When artificial tears and lid care are not enough, prescription anti-inflammatory drops are the standard next step. The most widely prescribed options include cyclosporine (Restasis and a newer nanomicellar formulation called Cequa) and lifitegrast (Xiidra). Both work by calming the immune-driven inflammation on the eye surface that perpetuates the dry eye cycle. These drops take weeks to months to show full benefit, which is one reason many patients give up on them too early.

Real-world data on persistence gives a sense of the challenge. In a large retrospective analysis of over 7,000 patients, roughly half of those on the nanomicellar cyclosporine formulation were still using it after a year, compared to about 39 percent on traditional cyclosporine and 44 percent on lifitegrast.²¹ The dropout rates are high across the board, often because of stinging on instillation or the slow onset of relief. If your eye doctor prescribes one of these, sticking with it for at least two to three months before judging effectiveness is reasonable.

A newer option takes a completely different approach. Varenicline nasal spray (Tyrvaya) stimulates a nerve pathway in the nose that triggers natural tear production. In two large trials, it produced rapid improvements in tear production within four weeks, with benefits sustained through twelve weeks in a longer-term study.²² Because it works through the nervous system rather than directly on the eye, it sidesteps the burning and stinging that cause so many patients to abandon eye drops. The most common side effect is sneezing.

In-Office Procedures for Stubborn Cases

When home treatments and prescription drops fall short, several office-based procedures target meibomian gland dysfunction more aggressively.

Thermal pulsation devices like LipiFlow apply controlled heat to the inner eyelid surface while simultaneously applying gentle pressure to express blocked glands. This approach improved tear stability and reduced symptom scores in pooled trial data.²³ However, long-term follow-up shows that dry eye symptoms can persist after LipiFlow, suggesting that gland dysfunction is sometimes only one piece of the puzzle.²³

Intense pulsed light (IPL) therapy, originally developed for skin conditions, has gained traction for dry eye. It delivers broad-spectrum light pulses to the skin around the eyes, reducing inflammation in nearby blood vessels and, in some cases, killing Demodex mites that contribute to lid disease. Current evidence shows IPL improves symptoms and objective measures like tear stability and lipid layer thickness.²⁴ The catch is that benefits tend to fade around six months after the initial course, so maintenance sessions are usually needed. For that reason, researchers recommend IPL as an add-on to standard care rather than a standalone first-line treatment.²⁴

A network meta-analysis comparing the two found that IPL produced a greater improvement in tear stability time than LipiFlow, while LipiFlow showed a bigger reduction in one widely used symptom questionnaire. Importantly, no head-to-head trials exist, so these comparisons are indirect and should be taken with caution.²⁵ Neither procedure is cheap, and insurance coverage varies widely.

Punctal Plugs and Scleral Lenses

If your eyes produce some tears but not enough, your doctor may suggest punctal plugs. These are tiny silicone or collagen inserts placed into the tear drainage ducts at the inner corner of your eyelids, slowing the drainage of tears off the eye surface. A meta-analysis found that plugs significantly improved tear stability, tear volume, symptom scores, and surface staining compared to controls.²⁶ Temporary collagen plugs dissolve on their own in a few months, making them a good trial run before committing to semi-permanent silicone versions. The main risks are mild irritation and occasional spontaneous loss of the plug.

For severe dry eye that resists other treatments, scleral contact lenses offer a different strategy. These large-diameter lenses vault over the cornea, creating a fluid-filled reservoir that keeps the eye surface constantly bathed in moisture. In a small study of patients with moderate to severe dry eye, the majority who completed fitting reported decreased discomfort, reduced need for artificial tears, and improved vision over a follow-up period averaging about 18 months.²⁷ Scleral lenses require a specialty fitting and have a learning curve for insertion and removal, but for people with conditions like Sjögren’s or severe post-surgical dryness, they can be transformative.

Omega-3 Supplements and Diet

Omega-3 fatty acid supplementation is one of the most-studied nutritional interventions for dry eye, and the evidence has largely been positive. A meta-analysis of randomized controlled trials found that omega-3 supplements improved dry eye symptoms, tear stability, tear production, corneal staining, and tear saltiness compared to placebo.²⁸ One trial specifically tested a re-esterified omega-3 formulation and saw significant improvements in tear stability and symptom scores at twelve weeks, along with a drop in a marker of ocular surface inflammation.²⁹

The benefit appears to be strongest in people who start with low omega-3 levels. One study found that improvements in symptoms and tear film measures were significantly better in patients whose baseline omega-3 index was below 4 percent.³⁰ If you already eat fatty fish several times a week, supplements may add less. For someone whose diet is low in these fats, adding a quality fish oil or algae-based supplement is a low-risk intervention worth trying alongside other treatments. Give it at least eight to twelve weeks to see meaningful changes.

When It Feels Like Dry Eye but Is Not

One of the more frustrating scenarios for patients and clinicians alike is when someone has all the symptoms of dry eye — burning, stinging, tearing, light sensitivity — but the clinical signs (tear volume, surface staining, tear stability) look relatively normal. Researchers have identified that in some of these cases the problem is not the tear film at all but rather a malfunction in the sensory nerves of the cornea, a condition sometimes called neuropathic ocular pain.³¹ In these patients, the nerves are sending pain signals independent of any actual surface dryness, much like how phantom limb pain occurs after an amputation.

This distinction has real treatment implications. Standard dry eye therapies like artificial tears, anti-inflammatory drops, and warm compresses often provide little relief for neuropathic ocular pain. Instead, treatment may involve low-dose nerve-modulating medications, autologous serum tears (made from the patient’s own blood), or other approaches borrowed from chronic pain management. If you have been treated aggressively for dry eye with minimal improvement and your eye surface looks healthy on exam, it is worth asking your eye doctor whether neuropathic pain could be contributing.

CPAP Masks and Nighttime Dryness

People who use continuous positive airway pressure (CPAP) machines for sleep apnea commonly develop dry eye symptoms, and the mechanism is straightforward: air leaking from the mask, especially at the bridge of the nose, blows directly across the eye surface for hours while you sleep. A study of obstructive sleep apnea patients using masks found that tear stability, symptom scores, and eyelid assessments all worsened after initiating mask therapy, along with changes in lipid layer thickness and tear volume.³² If you wake up with dry, irritated eyes and use a CPAP, the mask fit is the first thing to address. A properly fitted mask that minimizes upward air leak, or a switch to a different mask style, can dramatically reduce morning dryness. Nighttime lubricating ointments or moisture-chamber goggles worn over the eyes during sleep are additional options your sleep medicine or eye doctor can recommend.
