Fixing dry eyes starts with understanding what’s causing them, because the best treatment depends on whether your eyes aren’t producing enough tears or whether your tears are evaporating too fast. Most people can get significant relief with a combination of over-the-counter drops, simple daily habits, and environmental changes. More stubborn cases may need prescription medication or in-office procedures.
Why Your Eyes Feel Dry
Your tear film has three layers, and a problem with any of them can leave your eyes feeling gritty, burning, or watery (yes, watery eyes can actually be a sign of dryness). The outermost layer is a thin oil coating produced by tiny glands in your eyelids called meibomian glands. This oil layer prevents your tears from evaporating too quickly. Beneath it sits the aqueous layer, which makes up the bulk of your tears and handles lubrication, washing away debris, and nourishing your cornea. The innermost mucin layer acts like a bonding agent, helping the watery layer spread evenly across the eye’s surface.
When the oil-producing glands get clogged or stop working properly, a condition called meibomian gland dysfunction, your tears evaporate before they can do their job. This is the most common form of dry eye. The other major type happens when your lacrimal glands simply don’t produce enough of the watery layer. Many people have a mix of both.
Choosing the Right Eye Drops
Artificial tears are the first line of defense, and the shelf at any pharmacy can feel overwhelming. The most important decision is whether to use preserved or preservative-free drops. Preserved drops contain chemicals like benzalkonium chloride (BAK) that prevent bacterial growth in the bottle but can damage the surface cells of your eye over time, especially with frequent use. If you have mild dryness and use drops four to six times a day or less, preserved drops are generally fine.
If you’re reaching for drops more often than that, or if your dry eye is moderate to severe, switch to preservative-free single-use vials. Preservative-free formulations are especially important for people with significant surface damage or anyone already using other medicated eye drops. The toxicity of preservatives increases when your tear production is low, because there’s less fluid to dilute and wash away the chemical with each blink.
Beyond the preservative question, drops come in different thicknesses. Thinner, watery drops provide quick relief but don’t last long. Gel drops and ointments coat the surface longer but can blur your vision temporarily, making them better suited for bedtime use.
Warm Compresses and Lid Hygiene
If your dry eye is driven by clogged oil glands, warm compresses can help soften and release the blocked oils. But the details matter more than most people realize. Your eyelid glands need to reach at least 104 to 106°F (40 to 41°C) before the thickened oils inside them start to melt. A lukewarm washcloth that cools off in 30 seconds won’t cut it.
Microwavable eye masks designed to hold heat are more effective than a wet cloth because they maintain temperature longer. Place the mask over closed eyes for 10 to 15 minutes, then gently massage your lids from top to bottom on the upper lid and bottom to top on the lower lid. This helps push the loosened oil out of the glands and onto your tear film. Doing this once daily is the standard recommendation, though it’s a real time commitment and works best when you stay consistent over weeks.
Lid scrubs with diluted baby shampoo or pre-made lid wipes can also help by removing bacteria and debris along the lash line that contribute to gland blockage and inflammation.
Screen Time and the 20-20-20 Rule
People blink about 15 to 20 times per minute during normal conversation but as few as 3 to 4 times per minute while staring at a screen. Each blink spreads a fresh layer of tears across your eye, so fewer blinks means faster evaporation and more dryness. This is why your eyes often feel worst at the end of a workday.
The 20-20-20 rule is a simple fix: every 20 minutes, look at something 20 feet away for 20 seconds. This relaxes the focusing muscles in your eyes and naturally prompts more complete blinks. You can also make a conscious effort to blink fully and slowly a few times whenever you think of it during screen work. Positioning your monitor slightly below eye level helps too, because looking downward narrows the exposed surface of your eye, reducing evaporation.
Adjust Your Environment
Dry indoor air is one of the most overlooked contributors to dry eye, especially during winter months when heating systems strip moisture from the air. Aim for indoor humidity of 45% or higher. A tabletop humidifier near your workspace or bedside can make a noticeable difference within days.
Ceiling fans, car air vents pointed at your face, and forced-air heating all accelerate tear evaporation. Redirecting vents away from your eyes is a zero-cost fix that helps immediately. If you spend time outdoors in wind or dry climates, wraparound sunglasses create a small pocket of still, more humid air around your eyes.
Omega-3 Supplements
Omega-3 fatty acids from fish oil may help by reducing inflammation on the eye’s surface and improving the quality of the oil layer in your tears. The dosage used in many clinical studies is 180 milligrams of EPA and 120 milligrams of DHA, taken twice daily. Check the label on any fish oil supplement carefully, because the total milligrams of fish oil listed on the front of the bottle is not the same as the EPA and DHA content inside.
Results from omega-3 studies have been mixed. Some people notice meaningful improvement after two to three months of consistent use, while large trials have shown more modest benefits. It’s a reasonable, low-risk addition to your routine, but unlikely to solve dry eye on its own.
Prescription Treatments
When drops and lifestyle changes aren’t enough, prescription options target the underlying inflammation that drives chronic dry eye. Two widely used medications work by calming the immune response on the eye’s surface. Cyclosporine (sold as Restasis or Cequa) blocks the overactive immune cells that attack tear-producing tissue. Lifitegrast (Xiidra) works differently, preventing inflammatory cells from latching onto the eye’s surface in the first place. Both take several weeks to reach full effect, and some people experience stinging when they first start using them.
A newer option, perfluorohexyloctane (Miebo), is the first prescription drop specifically approved for dry eye caused by meibomian gland dysfunction. Rather than targeting inflammation, it acts as an artificial oil layer, stabilizing your tears and slowing evaporation. It’s preservative-free and used four times daily.
In-Office Procedures
For meibomian gland dysfunction that doesn’t respond to warm compresses alone, two in-office treatments can clear blocked glands more effectively. LipiFlow applies controlled heat and gentle pressure directly to the inner eyelid surface, expressing clogged oils in a single 12-minute session. Studies show symptom relief lasting up to 9 months from one treatment. Intense pulsed light (IPL) therapy uses broad-spectrum light pulses around the eye area to reduce inflammation and improve gland function, typically requiring three to four sessions spaced over several weeks to achieve similar results.
Both treatments are comparably effective. LipiFlow offers the convenience of fewer visits, while IPL may provide additional benefits for people with rosacea or visible blood vessels around the eyelids that contribute to inflammation.
Punctal Plugs
If your eyes don’t produce enough tears, your doctor may suggest punctal plugs. These are tiny inserts placed into the small drainage openings (puncta) in the inner corners of your eyelids. They work like a stopper in a bathtub: by blocking the drain, tears stay on your eye’s surface longer instead of flowing down into your nasal passages.
Temporary plugs made of collagen dissolve on their own within a few weeks to months. They’re often used as a trial run to see if blocking the drains actually helps your symptoms. If they do, semi-permanent silicone plugs can be placed in a quick, painless office visit. These stay in place until removed by your eye doctor, though they occasionally fall out on their own. The procedure takes just a few minutes and most people don’t feel the plugs once they’re in.
