The most effective thing you can do for dry eyes depends on what’s causing them, but most people get meaningful relief from a combination of over-the-counter eye drops, environmental changes, and screen habits. Dry eye happens when your tear film breaks down too quickly or your eyes don’t produce enough tears to stay lubricated. The good news is that mild to moderate cases usually respond well to simple, at-home strategies, while more stubborn cases have a growing list of prescription and in-office options.
Why Your Eyes Feel Dry
Your tear film isn’t just saltwater. It’s a layered coating with a watery mucus base (produced by your tear glands and the surface cells of your eye) topped by a thin oil layer secreted by tiny glands in your eyelids. The water keeps your eye moist and delivers protective proteins. The oil layer seals that moisture in and prevents it from evaporating between blinks. When either layer is disrupted, tears become unstable, evaporate too fast, and leave the eye’s surface exposed.
That exposure triggers a cycle: irritation leads to inflammation, which damages the surface cells and nerves, which further destabilizes the tear film. This is why dry eye often feels like it gets worse over time if you don’t address it. Common symptoms include burning, grittiness, blurred vision that clears when you blink, and, paradoxically, watery eyes (your body’s emergency reflex to coat an irritated surface).
Choosing the Right Eye Drops
Artificial tears are the first-line treatment for most people, but not all drops work the same way. There are two broad categories worth understanding.
Aqueous-based drops contain water-soluble polymers that mimic your natural mucus layer. They lubricate the surface, increase tear thickness, and slow down how fast tears drain away. These are the best starting point if your eyes feel dry, gritty, or irritated throughout the day.
Lipid-based drops contain mineral oils designed to thicken or replace the oil layer of your tear film. They don’t add moisture directly but seal in whatever moisture is already there. If your main issue is tears that evaporate too quickly (often caused by clogged oil glands in the eyelids), a lipid-based drop may work better than a standard aqueous one.
If you’re using drops more than three or four times a day, switch to preservative-free formulations. The most common preservative in eye drops, benzalkonium chloride, can itself cause eye irritation, worsen dryness, and damage the corneal surface with repeated use. The European Medicines Agency notes that long-term use of drops containing this preservative is associated with increased adverse effects, and preservative-free options are specifically recommended for people with ongoing dry eye. Preservative-free drops come in single-use vials or specialized multi-dose bottles.
Screen Time and the 20-20-20 Rule
Staring at a screen dramatically reduces your blink rate. Normally you blink about 15 to 20 times per minute, but during focused screen work that number can drop by half or more. Each missed blink is a moment your tear film goes without being refreshed, so it thins out and breaks apart.
The simplest fix is the 20-20-20 rule: every 20 minutes, look at something at least 20 feet away for 20 seconds. This gives your eyes a chance to refocus and recover. Consciously blinking a few extra times during those breaks helps re-coat the surface. Positioning your monitor slightly below eye level also helps, because looking downward narrows the opening between your eyelids and exposes less of your eye’s surface to the air.
Environmental Changes That Help
Your surroundings have a bigger impact on tear stability than most people realize. Indoor humidity of about 45% or higher is best for your eyes. In winter or in air-conditioned spaces, humidity can drop well below that. A simple room humidifier near your desk or bedside can make a noticeable difference within days.
Direct airflow is another major trigger. Car vents, ceiling fans, forced-air heating, and even the draft from a window can accelerate tear evaporation. Redirect vents away from your face, and if you work near an air conditioning outlet, consider repositioning your desk. Wearing wraparound sunglasses outdoors on windy days serves the same purpose by creating a small pocket of still, humid air around your eyes.
Warm Compresses for Clogged Oil Glands
Many cases of dry eye trace back to meibomian gland dysfunction, where the oil-producing glands along your eyelid margins become blocked. Without that oil layer, tears evaporate too quickly regardless of how much fluid your eyes produce. You can often tell this is your issue if your eyelids feel crusty in the morning or your eyes burn more than they feel dry.
A warm compress applied to closed eyelids for 5 to 10 minutes softens the hardened oil plugging those glands. Use a clean, damp washcloth heated to a comfortably warm temperature, or a microwaveable eye mask designed to hold heat longer. After warming, gently massage your eyelids from the lash line outward to help express the softened oil. Doing this once or twice daily is one of the most effective self-care habits for evaporative dry eye.
Prescription Treatments
When drops and home care aren’t enough, several prescription options target the underlying inflammation or tear deficiency.
Anti-inflammatory eye drops containing cyclosporine (sold under several brand names) work by calming the chronic inflammation that suppresses tear production. They take 4 to 12 weeks of consistent, twice-daily use before you notice improvement, which is why many people give up too early. A newer formulation uses a water-free, preservative-free base that may improve comfort during application. Another anti-inflammatory drop, lifitegrast, works through a different pathway and can also reduce symptoms over several weeks of use.
A nasal spray containing varenicline takes a different approach entirely. It stimulates nerves in the nose that trigger your body’s natural tear, oil, and mucus production. Some people notice increased tear production within minutes of using it, making it a useful option for people whose glands still function but need a stronger signal to produce.
The FDA approved a new dry eye medication called acoltremon (brand name Tryptyr) in May 2025, designed to treat both the signs and symptoms of dry eye disease.
In-Office Procedures
For meibomian gland dysfunction that doesn’t respond well to home care, eye doctors offer device-based treatments that clear blocked glands more thoroughly than warm compresses alone.
Thermal pulsation devices (LipiFlow is the most widely known) apply controlled heat to the inner eyelid surface while simultaneously massaging the outer lid to express clogged glands. A single session takes about 12 minutes per eye. Clinical data shows it improves tear film stability and reduces symptom scores, though some people need repeat sessions over time.
Intense pulsed light (IPL) therapy, originally developed for skin conditions, has shown strong results for dry eye as well. A systematic review comparing the two approaches found that IPL was particularly effective at improving tear stability, roughly tripling the improvement in tear break-up time compared to LipiFlow. Both options are typically not covered by insurance and can cost several hundred dollars per session.
What About Omega-3 Supplements?
Omega-3 fatty acids are widely recommended for dry eye, but the largest clinical trial on the topic, the DREAM study, found they didn’t live up to the hype. Participants who took 3,000 mg of omega-3 daily for 12 months showed no significant improvement over those taking an olive oil placebo. The study’s lead investigators concluded that the evidence does not support omega-3 supplements for moderate to severe dry eye.
That doesn’t mean diet is irrelevant to eye health, but if you’re spending money on fish oil capsules specifically to treat dry eyes, the evidence suggests your money is better spent on preservative-free artificial tears or a quality heated eye mask.
Matching Your Approach to Your Symptoms
The most practical strategy is to layer treatments based on severity. Start with preservative-free artificial tears, warm compresses, the 20-20-20 rule, and a humidifier. Give these four to six weeks of consistent use. If your symptoms persist, a lipid-based drop or a different formulation may work better than what you tried first.
If home strategies plateau, a prescription anti-inflammatory drop or the varenicline nasal spray can address the deeper inflammation or tear deficiency driving your symptoms. For stubborn meibomian gland blockages, an in-office procedure can reset gland function in ways that compresses alone cannot. Many people end up using a combination: a prescription drop for the underlying problem, artificial tears for immediate comfort, and daily lid hygiene to keep oil glands clear.
