Dry eyes are one of the most common eye complaints, and the good news is that most cases respond well to a combination of simple changes and over-the-counter products. What works best depends on what’s causing your dryness: your eyes may not be producing enough tears, or your tears may be evaporating too quickly because the oily outer layer of your tear film is unstable. Understanding which problem you’re dealing with helps you pick the right approach.
Start With the Right Type of Eye Drops
Artificial tears are the first-line fix for most people, but not all drops work the same way. There are two broad categories, and they target different problems.
Aqueous-based drops are water-soluble lubricants that relieve burning, irritation, and general dryness by adding moisture to the eye’s surface. These work well if your eyes simply aren’t producing enough tears. Lipid-based drops, on the other hand, contain oils that seal in existing moisture by reinforcing the thin fatty layer that normally sits on top of your tear film. If your tears seem to dry out quickly, especially in air-conditioned rooms or in front of screens, a lipid-based drop is often more effective because it slows evaporation rather than just adding water.
If you’re using drops more than a few times a day, switch to preservative-free versions. The most common preservative in eye drops is a compound called BAK, which is mildly allergenic and increasingly toxic to the corneal surface with repeated, prolonged use. Preservative-free drops come in single-use vials and are especially important if you already have irritated or damaged eyes.
Warm Compresses for Clogged Oil Glands
Many cases of dry eye trace back to meibomian gland dysfunction, where the tiny oil glands along your eyelid margins become clogged or produce thickened secretions. Without that oil layer, tears evaporate off your eye in seconds. The fix is surprisingly low-tech: heat.
Research shows the optimal temperature to soften and release blocked gland oils is about 40 to 42°C (104 to 108°F), which is comfortably warm against the skin. A microwavable eye mask or a clean washcloth soaked in hot water and wrung out works well. Hold it against closed eyelids, reheating as needed to maintain consistent warmth. Most eye care professionals recommend 10 to 15 minutes per session, done daily during flare-ups and a few times a week for maintenance. After warming, gently massage your eyelids from the lash line outward to help express the softened oils.
Control Your Environment
Your surroundings play a bigger role than most people realize. Indoor humidity of about 45% or higher is ideal for minimizing tear evaporation. In winter, heated air can drop indoor humidity into the teens. A simple hygrometer (available for a few dollars) tells you where you stand, and a humidifier in your bedroom or workspace can make a noticeable difference within days.
Beyond humidity, direct airflow is a major aggravator. Ceiling fans, car vents pointed at your face, and forced-air heating all strip moisture from the eye surface. Redirect vents away from your face when possible. If you spend long hours at a computer, your blink rate drops significantly, so making a conscious effort to blink fully every few seconds helps. Some people find that positioning their monitor slightly below eye level reduces the exposed surface area of the eye, slowing evaporation.
Omega-3 Fatty Acids
Fish oil supplements have shown benefit for dry eye in multiple studies, likely because the omega-3 fats help improve the quality of the oily tear layer and reduce inflammation on the eye’s surface. The dosage used in much of the research is 180 mg of EPA and 120 mg of DHA, taken twice daily. That’s a modest amount, roughly what you’d get from one standard fish oil capsule twice a day. Results aren’t instant. Most people need several weeks of consistent use before noticing improvement, and the benefit builds over time.
You can also get these fats from dietary sources: fatty fish like salmon, mackerel, sardines, and anchovies are the richest options. Flaxseed and walnuts provide a plant-based omega-3, though your body converts it to the active forms less efficiently.
Prescription Options for Persistent Dryness
When over-the-counter drops and lifestyle changes aren’t enough, prescription eye drops can address the underlying inflammation that drives chronic dry eye. The most widely prescribed option works by calming the immune cells on the eye’s surface. It suppresses the activation of certain white blood cells and reduces the release of inflammatory signals, which allows the tear glands to function more normally. Over time, it also increases the number of mucus-producing cells on the eye’s surface, improving tear quality.
The catch is patience. The therapeutic effect generally emerges after several weeks, and it can take more than six months to reach full effectiveness. Many people experience mild stinging when they first start using these drops, which tends to improve as the inflammation on the eye’s surface resolves. A second class of prescription drops works by blocking a specific inflammatory protein involved in dry eye, with a somewhat faster onset, though some users report a temporary bitter taste after application.
For short-term flare-ups, your eye doctor may prescribe a brief course of anti-inflammatory steroid drops to bring symptoms under control quickly while a longer-acting treatment takes effect.
In-Office Procedures
If your eyes don’t retain tears well, tiny plugs inserted into the tear drainage channels (the small openings at the inner corner of each eyelid) can keep tears on your eye longer. These come in two types: dissolvable collagen plugs that last a few weeks to months, and semi-permanent silicone plugs that stay in place until removed. Both types work equally well in the short term. In clinical testing, both significantly increased the volume of tears on the eye’s surface and nearly doubled the time tears remained before draining away. Collagen plugs are often used as a trial run: if they help, your doctor may place longer-lasting silicone ones.
For meibomian gland dysfunction that doesn’t respond to home warm compresses, in-office thermal pulsation treatments apply controlled heat directly to the inner eyelid while simultaneously expressing the glands. These sessions typically last about 12 minutes and can provide relief lasting several months.
Scleral Lenses for Severe Cases
When drops, plugs, and medications aren’t enough, scleral contact lenses offer a more intensive solution. These are large-diameter lenses that vault over the entire cornea without touching it, resting instead on the white of the eye. Before insertion, you fill the bowl of the lens with saline solution, which then sits against your eye all day as a continuous fluid reservoir. This bathes the corneal surface in moisture for as long as the lens is worn, providing relief that drops simply can’t match for people with severe or treatment-resistant dry eye.
Scleral lenses require a custom fitting and a bit of a learning curve for insertion and removal, but many people with severe dry eye describe them as life-changing, especially those who had difficulty reading, driving, or working on screens before.
Daily Habits That Add Up
Small adjustments throughout the day compound into meaningful relief. Stay well-hydrated, as even mild dehydration reduces tear production. If you wear contact lenses, switch to daily disposables or reduce your wearing time on days when dryness is worse. Wraparound sunglasses outdoors block wind and reduce evaporation. At night, if you wake with scratchy, stuck-together eyes, a thicker gel or ointment-type lubricant applied before bed provides longer-lasting moisture than standard drops, though it will blur vision temporarily.
Cleaning your eyelids daily with a gentle lid scrub or diluted baby shampoo removes debris and bacteria that contribute to gland blockage and inflammation along the lash line. This is especially helpful if you notice crustiness or flaking at the base of your lashes.
