The short version
- Warm compresses soften the thickened oil that clogs the glands along your eyelids.
- The target is an eyelid temperature of about 40°C (104°F) for around ten minutes. A washcloth cools too quickly to stay there.
- A mask made to hold heat does far better. A 2024 review suggested a moist-heat mask, microwavable or self-heating, when possible.
- Follow each session with a gentle lid massage so the softened oil can flow.
- Give it two to four weeks of daily use before you judge the results.
Why heat helps
Along the edge of each eyelid sit dozens of meibomian glands. Each blink squeezes out a little oil that spreads over your tears and slows their evaporation. In meibomian gland dysfunction, the main cause of evaporative dry eye, that oil thickens from something like olive oil into something closer to toothpaste. It blocks the gland openings, and tears evaporate faster. In one clinic-based study, 86% of the dry eye patients whose type could be identified had signs of this1 Lemp et al., Cornea, 2012 (opens in a new tab). Distribution of aqueous-deficient and evaporative dry eye in a clinic-based patient cohort..
Heat melts the thickened oil so it can move again. That’s the whole idea. But thickened oil needs real warmth, sustained long enough to reach the glands through the eyelid.
Why a washcloth usually isn’t enough
A 2024 review of warm compress research found that the target is an eyelid temperature of about 40°C (104°F), and that hot towels need frequent re-warming to stay there, which made them relatively ineffective in longer studies2 Lee, Ophthalmology and Therapy, 2024 (opens in a new tab). Evidence-Based Strategies for Warm Compress Therapy in Meibomian Gland Dysfunction.. When researchers tested how well different eyelid warming masks held their heat, every mask reached 40°C quickly and stayed there for at least five minutes, except the facecloth3 Lacroix et al., Contact Lens & Anterior Eye, 2015 (opens in a new tab). Ex vivo heat retention of different eyelid warming masks..
So the classic advice, a warm washcloth for a minute or two, mostly delivers comfort, not treatment. A mask designed to hold heat does the job properly with far less effort.
How to do it, step by step
- Heat the mask exactly as its instructions say.Microwavable masks usually need only 20 to 30 seconds. Test it on the inside of your wrist first. It should feel comfortably warm, never painful.
- Close your eyes and rest it on them for ten minutes.If it cools noticeably, warm it again. Relax, put on a podcast, make it part of your evening.
- Massage straight away, while the oil is soft.With a clean fingertip, gently roll along the upper lid from just below the brow down toward the lashes, then along the lower lid upwards toward the lashes. Five or six sweeps each. Press on the lid, never on the eyeball.
- Clean the lash line.A lid wipe or cleanser clears the oil and debris you’ve just moved.
- Repeat once or twice a day, every day.Consistency matters more than intensity. Many people notice a difference within two to four weeks.
Choosing a heated eye mask
There are three main kinds:
- Microwavable bead masks are cheap, reusable and hold heat for around ten minutes. The Bruder mask is one of the best known.
- Electric or USB masks hold a steady temperature for as long as you want, which is handy if you forget to re-warm. Pick one with a timer and automatic shut-off.
- Self-heating disposable masks warm up when opened. They’re convenient for travel but get expensive for daily use.
A 2024 review of warm compress studies covered hot towels, microwavable masks and self-heating masks, but not electric ones. It suggested that masks giving off moist heat, such as the Bruder mask, hold their heat better, and one study in it found fewer Demodex mites on the lashes with a moist-heat mask. It advised using a moist-heat mask, microwavable or self-heating, when possible2.
Heated eye mask
Bruder Moist Heat Eye Compress
A microwavable mask made to hold its warmth far longer than a washcloth, which cools within minutes. Steady warmth over several minutes is what thickened gland oil needs to soften.
Worth knowing. Test it on your wrist every time. Eyelid skin is thin and burns easily.
Lid cleansing pads
OcuSoft Lid Scrub Plus
Pre-soaked pads for cleaning the lash line. The easiest way to turn lid hygiene into a daily habit.
Worth knowing. Use it once a day to start. Scrubbing harder or more often can irritate the lids.

Staying safe
- Eyelid skin is some of the thinnest on your body. Always test the temperature, and never heat a mask for longer than its instructions say, since microwaves can create hot spots. Microwavable masks have been linked to skin burns2.
- Skip compresses and see a doctor if your eye is red and painful with discharge, which can mean an infection.
- If you’ve had recent eye surgery, ask your surgeon before using heat or lid massage. Our guide to dry eye after eye surgery covers what helps while you heal.
- If you have reduced sensation in your face, for example from diabetes or nerve damage, use a device with a controlled temperature.
- Wash or wipe your mask regularly, and replace it if it’s damaged.

If compresses aren’t working
If you’ve done a proper routine every day for a month and your eyes aren’t improving, your glands may be too blocked for home heat to clear, or something else, such as eyelid mites or inflammation, may be involved. A dry eye clinic can image your glands and offer in-office options. One is LipiFlow, a thermal pulsation device that heats the inner eyelids and gently presses them in a single session. A 2024 Cochrane review of 13 trials found that it performed about as well as other common treatments, such as warm compresses, though the evidence was low or very low certainty4 Pucker et al., Cochrane Database of Systematic Reviews, 2024 (opens in a new tab). LipiFlow for the treatment of dry eye disease.. In one randomized trial, a single LipiFlow treatment worked at least as well as three months of twice-daily lid care5 Finis et al., The Ocular Surface, 2014 (opens in a new tab). Evaluation of an automated thermodynamic treatment (LipiFlow) system for meibomian gland dysfunction: a prospective, randomized, observer-masked trial.. Intense pulsed light is another option.

Common questions
How long should I use a warm compress for dry eyes?
About ten minutes, once or twice a day, keeping your eyelids at about 40°C (104°F). A washcloth cools within a few minutes, so it mostly feels nice without doing much for the glands.
Is it better to do it in the morning or at night?
Whichever you’ll stick to. Many people prefer evenings, when they can relax. If your eyes are worst in the morning, a morning session helps clear oil that thickened overnight.
Can a warm compress make dry eye worse?
Not usually. The treatment studies in a 2024 review of warm compresses reported no side effects, but microwavable masks have been linked to skin burns, so never heat one for longer than its instructions say. A compress that’s too hot can irritate or burn the lid skin, and a dirty one can spread bacteria. If your eyes feel worse after compresses, stop and see an eye doctor.
Is moist heat or dry heat better for dry eyes?
Moist heat, where you can. A 2024 review of warm compress studies suggested that moist-heat masks, such as the Bruder mask, hold their heat better. It advised using a moist-heat mask, microwavable or self-heating, when possible.
How long until warm compresses work?
Some people feel relief right away. Improvement in gland function takes longer, often a few weeks of daily use.
Should I use a warm compress for a stye?
Warm compresses are commonly recommended for styes and chalazia to help them drain. Never squeeze a stye, and see a doctor if it spreads, becomes very painful or affects your vision.
