Producing more tears when you have dry eyes comes down to two goals: stimulating your tear glands to make more fluid and keeping the tears you do produce from evaporating too quickly. Most people with dry eyes have some combination of both problems, and the most effective approach addresses each one. Here’s what actually works, from simple daily habits to medical options.
How Your Body Makes Tears
Understanding the basics helps explain why certain treatments work. Your eyes produce tears through a feedback loop that starts at the surface of the eye itself. Sensory nerves in the cornea and conjunctiva detect dryness or irritation and send signals to a processing center in the brain called the lacrimal nucleus. That center weighs the input (including emotional signals) and sends a graded response back through parasympathetic and sympathetic nerves to the lacrimal gland, which then secretes water, electrolytes, and proteins onto the eye’s surface.
This isn’t a simple on/off reflex. The brain modulates the response based on multiple inputs, which is why emotional crying, cold wind, and onion fumes all produce tears through slightly different pathways. It also explains why damage or dysfunction at any point in this loop, from the corneal nerves to the gland itself, can reduce tear output.
Warm Compresses for Better Tear Quality
The oily outer layer of your tear film prevents evaporation, and it comes from tiny glands along your eyelid margins called meibomian glands. When the oil in these glands thickens or hardens, it can’t flow properly, and your tears evaporate faster. This is the single most common cause of dry eye symptoms.
A warm compress melts that thickened oil and gets it flowing again. Research shows the target temperature is about 40 to 42°C (104 to 107°F), which is warm enough to soften the oil to 90% of its maximum fluidity. A standard recommendation is 10 minutes per session, once or twice daily. Microwavable eye masks or gel packs hold heat more consistently than a washcloth, which cools quickly and needs frequent reheating. After removing the compress, gently massage your closed eyelids from top to bottom on the upper lid and bottom to top on the lower lid to push the loosened oil out of the glands.
Blink More, Especially at Screens
Every time you blink, you spread a fresh layer of tears across your eye and squeeze oil from the meibomian glands. During screen use, your blink rate drops significantly, and many of the blinks that do happen are incomplete, meaning your upper lid doesn’t fully meet the lower one. Over a full workday, this adds up to substantial tear film disruption.
The 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds) has been shown to reduce dry eye symptoms and digital eye strain, even though a two-week study didn’t find measurable changes in tear film parameters on clinical tests. The practical benefit seems to come from resetting your blink pattern and giving your eyes periodic relief. Placing a sticky note on your monitor or using a timer app can help you remember, since the hardest part is breaking concentration.
Omega-3 Fatty Acids
Omega-3s, particularly EPA and DHA from fish oil, may improve the oil layer of your tears and reduce inflammation on the eye’s surface. Clinical trials have used doses ranging widely, from 135 mg to 3,000 mg of combined EPA and DHA per day, which makes it hard to pin down an ideal number. Many eye care professionals suggest aiming for roughly 1,000 to 2,000 mg of combined EPA and DHA daily, either from supplements or from eating fatty fish like salmon, mackerel, or sardines two to three times a week.
Results aren’t immediate. Most studies that showed benefit ran for at least three months, so consistency matters more than any single dose.
Artificial Tears and How to Use Them
Over-the-counter artificial tears are the first line of defense for most people. They don’t make your eyes produce more tears, but they replace what’s missing. Preservative-free formulas in single-use vials are gentler if you’re using drops more than four times a day, since the preservatives in bottled drops can irritate the eye with frequent use.
For mild dryness, a thin, watery drop works well and won’t blur your vision. If your eyes feel dry within an hour of using drops, a thicker gel formula lasts longer on the surface. Ointments provide the most lasting relief but blur vision significantly, so they’re best used at bedtime. Applying a drop before activities that trigger dryness (reading, driving, screen work) is more effective than waiting until symptoms flare.
Nasal Spray That Triggers Natural Tears
A prescription nasal spray (varenicline, sold as Tyrvaya) works by activating the same nerve pathway your body uses naturally. It stimulates nerve receptors inside the nose that connect to the trigeminal parasympathetic pathway, which signals the lacrimal gland to produce a full, balanced tear film, not just water, but also the proteins and oils that come with natural tears. This is a notable advantage over artificial tears, which only approximate one component of the tear film.
The spray is used twice daily, one puff in each nostril. The most common side effect is sneezing, which is temporary and tends to lessen over time.
Punctal Plugs to Keep Tears on the Eye
Your tears drain through tiny openings at the inner corners of your eyelids called puncta. Punctal plugs are small devices inserted into these openings to slow drainage, keeping tears on the eye’s surface longer. It’s like putting a stopper in a sink to keep the water level higher.
There are two main types. Temporary collagen plugs dissolve on their own after a few days to weeks, and they’re often used as a trial run to see if blocking the drainage helps your symptoms. If the trial works, semi-permanent silicone plugs can be placed. These last for years and can be removed at any time if they cause irritation or excessive tearing. Both types significantly increase the volume of tears on the eye’s surface, and studies show their effectiveness is comparable. The insertion is quick, done in the office, and generally painless.
Intense Pulsed Light for Gland Dysfunction
If meibomian gland dysfunction is a major contributor to your dry eyes and warm compresses aren’t enough, intense pulsed light (IPL) therapy is an in-office procedure that targets the root problem. IPL uses controlled pulses of light applied to the skin around the eyelids. It works through several mechanisms: softening and liquefying hardened gland secretions, reducing bacterial overgrowth and tiny mites (Demodex) that contribute to gland blockage, decreasing inflammation on the ocular surface, and stimulating collagen production in the eyelid skin so the lids maintain better contact with the eye during blinks.
A typical course involves three to four sessions spaced a few weeks apart, with maintenance sessions once or twice a year. It’s not covered by most insurance plans and costs several hundred dollars per session, but for people with significant gland dysfunction, the improvement in tear film stability can be substantial.
Environmental and Lifestyle Changes
Your surroundings have a direct impact on how quickly tears evaporate. Forced-air heating and air conditioning pull moisture from the air and from your eyes. A humidifier in your bedroom and workspace helps counteract this, particularly in winter. Positioning your computer screen slightly below eye level so you look slightly downward reduces the exposed surface area of your eye, which slows evaporation compared to looking straight ahead or up at a monitor.
Staying well-hydrated supports tear production in a general sense, though drinking extra water won’t cure dry eye on its own. Wraparound glasses or moisture chamber spectacles create a humid microenvironment around your eyes and block wind, which is useful outdoors or in drafty offices. If you sleep with a fan pointed at your face or your eyelids don’t fully close during sleep, nighttime exposure can cause significant morning dryness. A sleep mask or bedtime eye ointment addresses this.
How Dry Eye Severity Is Measured
If you see an eye care provider, one common test involves placing a small paper strip inside your lower eyelid for five minutes to measure how much moisture it absorbs. This is called a Schirmer test. Wetting more than 15 mm of the strip is normal. Between 10 and 15 mm suggests possible dry eyes. Five to 10 mm indicates moderate dryness, and less than 5 mm points to severe tear deficiency. Knowing where you fall on this scale helps guide which combination of the approaches above makes the most sense for your situation.
