What to Do If Your Eyes Are Dry: Tips and Treatments

Dry eyes respond well to a layered approach: start with preservative-free artificial tears and simple habit changes, then step up to prescription drops or in-office treatments if the irritation persists. The specifics depend on whether your eyes aren’t producing enough tears, or whether the tears you do produce are evaporating too quickly. Most people fall somewhere on that spectrum, and figuring out where you sit is the key to choosing a treatment that actually helps rather than one that just masks the discomfort for an hour.

What Makes Eyes Dry in the First Place

Your tear film is not just salt water. It has a layered structure: a mucus layer that sits against the eye’s surface, an aqueous (watery) middle layer, and an oily lipid layer on top that slows evaporation. A problem with any one of these layers can produce dry eye symptoms.¹ The mucus layer helps tears stick evenly across the cornea and plays a role in defending the eye against infection.²

The two main subtypes of dry eye are aqueous-deficient (your eyes don’t make enough of the watery component) and evaporative (the oily layer is weak, so tears dry up too fast). Evaporative dry eye, usually caused by dysfunction in the tiny oil glands along the eyelid margins, is the more common form. In practice, many people have a mix of both, which is part of why treatment can require some trial and error.³

Screens, Blinking, and Indoor Air

If your eyes feel worst at the end of a workday, screens are a likely culprit. When you’re focused on a digital device, your blink rate drops and a larger share of the blinks you do make are incomplete, meaning the upper lid doesn’t sweep all the way down. Full blinks are what spread fresh tears and lipids across the eye’s surface. Fewer and shallower blinks let the tear film thin out and evaporate between blinks, setting up a cycle of dryness and irritation.⁴ One study in adolescents found that those spending more than four hours a day on screens had roughly four and a half times the odds of digital eye strain symptoms compared to lighter users, and each additional blink per minute lowered those odds.⁵

The practical fix is the well-known 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. What most people skip is deliberately blinking a few extra times during that break, which is arguably the more important part. Positioning your monitor slightly below eye level also helps, because looking downward exposes less of the eye’s surface to the air.

Indoor environments compound the problem. Heated rooms in winter and air-conditioned spaces in summer tend to have low relative humidity, and as humidity drops, tears evaporate faster.⁶ Low humidity also destabilizes the lipid layer and can aggravate inflammation on the eye’s surface.⁷ A desktop humidifier near your workspace, or simply directing air vents away from your face, can make a real difference. Ceiling fans and car dashboard vents aimed at the windshield are sneaky culprits too.

Hormones and Other Biological Risk Factors

If you’re a woman going through perimenopause or menopause, dry eyes aren’t just bad luck. Sex hormones, both estrogens and androgens, influence the production of every layer of the tear film. As those hormone levels shift, tear composition and volume can change enough to trigger or worsen dry eye disease.⁸ Hormonal contraceptives, antiandrogen medications, and conditions like polycystic ovarian syndrome can have similar effects.⁹

Mental health medications deserve a mention here as well. Cross-sectional research has found associations between depression and anxiety, and the medications used to treat them, and dry eye symptoms.¹⁰ Antihistamines, decongestants, certain blood pressure drugs, and antidepressants are all known to reduce tear production. If your eyes turned dry around the same time you started a new medication, it’s worth raising the question with your prescriber rather than assuming it’s just aging.

Choosing the Right Eye Drops

Artificial tears are the first-line treatment for mild to moderate dry eye, and the sheer number of options on the pharmacy shelf can be paralyzing. The single most important distinction is between preserved and preservative-free formulations. Preserved drops contain chemicals like benzalkonium chloride (BAK) that prevent bacterial growth in multidose bottles, but BAK can irritate the ocular surface, particularly with frequent use.¹¹ If you’re using drops more than about four times a day, or if preserved drops sting or make things worse, switch to preservative-free single-use vials.

Beyond the preservative question, drops vary in viscosity. Thin, watery drops work for mild irritation and won’t blur your vision, but they wash away quickly. Thicker gel drops last longer but can smear your vision for a few minutes. Ointments are thickest of all and are best reserved for bedtime. For evaporative dry eye specifically, lipid-based drops that mimic the oily tear layer can help slow evaporation more than a watery formula would.

No artificial tear “cures” dry eye. They supplement what your eyes aren’t doing well on their own. If you find yourself reaching for drops every hour and still feeling dry, that’s a sign you need something that addresses the underlying cause rather than repeatedly topping off the tank.

Prescription Treatments

Two prescription eye drops have been widely available for moderate to severe dry eye. Cyclosporine (sold as Restasis and its generics, or the newer nanoemulsion Cequa) is an immunosuppressant that reduces the chronic inflammation driving many cases of dry eye. It typically takes two to three months of twice-daily use before you notice results, which is a long wait when your eyes hurt now, but the payoff is that your tear glands start functioning better.

Lifitegrast (Xiidra) works differently, blocking a specific inflammatory pathway involved in dry eye. In a post hoc analysis of two randomized trials, about seven in ten participants on lifitegrast achieved a meaningful improvement in eye dryness scores at day 84, compared with roughly five in ten on placebo. For people with moderate to severe disease, the odds of meaningful improvement were roughly 1.7 to 2.1 times higher with lifitegrast across all measured endpoints.¹² A six-month chart review also found that lifitegrast improved both signs (what the doctor sees on exam) and symptoms (what you feel).¹³ Common side effects include a temporary burning or stinging on application and a metallic taste in the mouth.

A newer option, perfluorohexyloctane (Miebo), is a non-aqueous eye drop approved specifically for evaporative dry eye. It sits on the tear film’s surface and slows evaporation, approaching the problem from a completely different angle than anti-inflammatory drops. In studies, it relieved symptoms within several weeks of use.¹⁴

In-Office Procedures

When drops alone aren’t cutting it, eye doctors have several procedural tools. The right one depends, again, on whether the problem is aqueous deficiency, evaporative loss, or both.

Punctal Plugs for Aqueous-Deficient Dry Eye

Punctal plugs are tiny silicone or collagen inserts placed into the tear drainage ducts at the inner corners of your eyelids. By slowing drainage, they keep your natural tears on the eye surface longer and reduce how often you need artificial tears.¹⁵ A meta-analysis covering over 1,600 patients found that punctal plugs produced meaningful improvements across multiple measures of dryness, including symptom scores and tear stability, with a retention rate of about 86 percent.¹⁶ The procedure takes a few minutes in the office and is reversible: the plug can be removed if it causes problems, and some types dissolve on their own after a few months.

Thermal Treatments for Meibomian Gland Dysfunction

If the problem is clogged oil glands along your eyelids, two device-based treatments aim to melt and clear that blocked oil. LipiFlow applies controlled heat and gentle pressure to the inner eyelid surface during a 12-minute session. Intense pulsed light (IPL), adapted from dermatology, delivers light pulses to the skin around the eyes to reduce inflammation and improve gland function.

A network meta-analysis comparing the two found that both improved tear film stability and symptom scores. IPL showed a somewhat larger improvement in tear breakup time, while LipiFlow showed a greater reduction in a commonly used symptom questionnaire (OSDI).¹⁷ Neither is a one-and-done fix; most patients need periodic retreatment. These procedures are not typically covered by insurance and can cost several hundred dollars per session, which is worth asking about before scheduling.

The Omega-3 Question

You’ll often see omega-3 fatty acid supplements recommended for dry eye, and the evidence is genuinely mixed. The biological rationale makes sense: omega-3s are converted into anti-inflammatory compounds that can reduce inflammation on the eye’s surface.¹⁸ A small randomized trial found that participants taking re-esterified omega-3 supplements for three months had significant improvements in tear stability, symptom scores, and an inflammatory marker on the ocular surface compared to placebo.¹⁹

But the largest and most rigorous trial to date, known as DREAM, threw cold water on the enthusiasm. That multicenter study randomized 535 participants to omega-3 supplements or olive oil placebo and found no significant difference in symptom scores, corneal staining, tear breakup time, or tear production between the two groups after 12 months.²⁰ One complication is that the olive oil placebo itself may have had mild anti-inflammatory effects, muddying the comparison.

Where does that leave you? Omega-3 supplements are unlikely to harm you (assuming reasonable doses), and some smaller studies suggest a benefit, but the strongest trial found nothing. If you’re already taking omega-3s for cardiovascular or other reasons, they might give you a modest edge. But for dry eye specifically, don’t rely on them as your primary treatment.

When Dry Eyes Signal Something Bigger

Persistent, severe dry eye that doesn’t respond well to standard treatments sometimes points to an underlying systemic condition. Sjögren’s syndrome, an autoimmune disorder that attacks moisture-producing glands, is the classic example. It causes severe aqueous-deficient dry eye and is associated with serious complications including corneal ulceration and scarring.²¹ If your dry eyes are accompanied by a persistently dry mouth, joint pain, or fatigue, mention those symptoms together to your doctor. Sjögren’s is often diagnosed years after symptoms begin because each symptom gets treated in isolation.

Dry eyes after LASIK or other refractive surgery are common and usually temporary, but occasionally they linger. The surgery cuts corneal nerves that normally trigger the reflex to produce tears. While corneal sensitivity and clinical signs of dryness typically return to near-normal within a year as nerves partially regenerate, some patients continue to experience subjective dryness, possibly because of residual abnormalities in corneal nerve signaling.²² If you’re considering LASIK and already have dry eye symptoms, discuss this with your surgeon beforehand, because pre-existing dryness can affect both surgical outcomes and post-operative comfort.

Options for Severe or Refractory Dry Eye

For people whose dry eye doesn’t respond adequately to drops, plugs, or thermal treatments, a few more intensive options exist. Scleral contact lenses are large rigid lenses that vault over the cornea entirely, creating a fluid reservoir between the lens and the eye that keeps the surface bathed in moisture all day.²³ A study of patients with conditions like Sjögren’s syndrome and Stevens-Johnson syndrome found that scleral lenses significantly improved visual acuity, reduced tear osmolarity (a measure of tear saltiness linked to dryness), and improved both symptom scores and quality-of-life measures over 12 months of wear.²⁴

Autologous serum eye drops are another option reserved for refractory cases. These are made from your own blood serum, which naturally contains proteins, growth factors, and vitamins found in real tears. They can promote healing of the ocular surface when nothing else has worked.¹⁴ The downside is that they require periodic blood draws, must be prepared at a compounding pharmacy, and need to be kept refrigerated.

What Happens When Dry Eye Goes Untreated

A lot of people assume dry eyes are just an annoyance, and for mild cases that respond to lubricating drops, that’s basically true. But chronic untreated dry eye can lead to genuine damage to the cornea. A large population-based study in Taiwan following patients over 17 years found that people with dry eye disease had roughly 2.7 times the rate of corneal surface damage compared to those without the condition. The risk was especially elevated in younger patients under 18 and in women.²⁵ Corneal damage from chronic dryness can include tiny erosions, scarring, and in rare severe cases, infection, all of which can affect vision.

This doesn’t mean every case of mild dryness will spiral. It means that if your eyes have been persistently uncomfortable for weeks or months and simple remedies aren’t helping, it’s worth getting an actual evaluation rather than cycling through different brands of artificial tears. An eye doctor can measure tear breakup time, stain the ocular surface to look for damage, and assess whether your oil glands are functioning. Using several of these tests together dramatically improves diagnostic accuracy compared to relying on any single test or symptom questionnaire alone.²⁶

Soft Bandage Lenses and Drug-Delivery Contact Lenses

Beyond scleral lenses, other types of therapeutic contact lenses are gaining ground. Soft bandage lenses can be placed over a damaged cornea to protect it while it heals, reducing friction from the eyelid and shielding the surface from the environment. Newer designs are being explored as vehicles for sustained drug delivery to the ocular surface, potentially replacing the need for frequent drop instillation throughout the day.²⁷ For people who struggle with the logistics of applying drops multiple times daily, whether due to arthritis, tremor, or simply being busy, a lens that releases medication gradually could be a meaningful quality-of-life improvement. These drug-eluting lenses are still largely in the research and early-adoption stage, but the approach reflects a broader trend in dry eye treatment: moving away from quick symptom relief toward sustained management that better mimics how a healthy eye maintains itself.
