There are plenty of reasons to try one: eyelids that feel heavy or crusty after waking, a stye starting to form, or simply wanting a few quiet minutes before bed. Whatever the reason, the method is the same. This guide walks through the kit, the method, why a flannel loses its heat sooner than you would think, and the signs that mean you should see someone rather than reach for a flannel.
What You Need
- A clean flannel or face cloth
- A bowl of warm water
- A towel to rest on
- Clean hands
- Cotton wool pads (for cleaning afterwards)
- A clock or timer
Putting together a warm compress for eyes takes about two minutes. Use a fresh, clean flannel each time, and a separate one for each eye if one eye is sore or sticky, so nothing is carried from one to the other.
How to Make a Warm Compress, Step by Step
-
1
Take out contact lenses and remove eye make-up. Wash your hands with soap and water.
-
2
Fill a bowl with warm water. Dab a little on your wrist: you want the warmth of a comfortable bath, never hot enough to make you pull away.
-
3
Soak and wring out the flannel. Squeeze it until it is damp but not dripping.
-
4
Lie back and close your eyes. Lay the folded flannel across both lids. Let it rest there without pressing.
-
5
Re-warm as it cools. Every minute or two, dip it back in the bowl and wring it out again.
-
6
Stop after 5 to 10 minutes. Pat the area dry with a clean towel.
How Warm, How Long, How Often?
Comfortable against your wrist. Eyelid skin is thin, so lean towards cooler rather than hotter.
Per session, re-warming the flannel as it cools.
The NHS figure for a stye. For general lid care, twice a day is typical.
These numbers come from the NHS. Its stye advice is to hold a warm flannel against the eye for 5 to 10 minutes, two to four times a day, and not to squeeze the stye or pull out the eyelash. Its guidance for blepharitis, or inflamed eyelids, uses the same 5 to 10 minutes, twice a day, followed by a gentle massage and clean.
Why a Flannel Cools Down So Quickly
Notice your flannel turning lukewarm almost straight away? That is normal. A wet cloth loses heat fast, which is why re-warming it matters so much.
An article in Acuity, the journal of the UK's College of Optometrists, puts numbers on this. Eyelids normally sit at about 34 to 35°C, and to soften the oils in the tiny glands along the lid edge they need to be raised to 40°C or more and kept there for roughly five minutes. Retired ophthalmic surgeon Professor Teifi James told the journal that a standard homemade hot flannel "does not deliver this sustained raised temperature" (Acuity, College of Optometrists, 2025).
The practical takeaway: keep the water warm and re-dip often. Been told to use warm compresses for an eye condition? Ask your optician whether a longer-lasting option would suit you better.
Other Ways to Apply Warmth
Microwavable Heat Bags
Reusable eye bags filled with beads or seeds are warmed in the microwave and hold their heat longer than a flannel. A patient leaflet from King's College Hospital mentions these as an alternative to cotton wool and warm water. Follow the maker's heating time exactly, and shake or test it on your wrist first, because microwaves can heat unevenly.
Self-Heating Steam Eye Masks
These single-use masks heat up on their own as soon as the sealed pouch is opened. With no water, microwave or mess involved, which makes them handy for travel or a quick break at your desk. Ours hit roughly 40°C in a couple of minutes and hold that warmth for as long as 40 minutes, with ear loops so you can lie back hands-free. They are a comfort product rather than a treatment, so for a diagnosed eye condition, check with your optician which type of warmth they recommend.
Wondering how a steam mask compares with a sleep mask or under-eye patches? Our eye mask comparison covers that.
Finishing Off: Massage and Clean
When warmth is being used for eyelid care, the NHS and hospital eye clinics pair it with two more steps, done straight afterwards while the lids are still warm:
- Massage: with your eyes closed, gently stroke the upper lid downwards towards the lashes, and the lower lid upwards towards the lashes. The NHS suggests around 30 seconds.
- Clean: wipe along the lash line with clean cotton wool or a cotton bud. The NHS notes a small amount of baby shampoo in water may help. Use a fresh pad for each eye, and never clean the inside of the lids.
Using a compress purely to relax? Then this part is optional.
When a Warm Compress Is Not the Answer
Do not use a warm compress, and get advice instead, if you have:
- eye pain, rather than mild soreness of the lid
- any change in your vision, such as blurring
- a very red eye, or the redness is spreading
- a stye that is very painful or swollen, or pus coming from the eye
- a recent eye injury, or eye surgery in the past few weeks
For eye pain, vision changes or very red eyes, the NHS says to ask for an urgent GP appointment or call 111 . For milder problems, a pharmacist is a good first stop.
Things People Wonder
Can I use a warm tea bag instead?
It is better not to. Tea bags are not sterile, can be too hot in the middle, and may leave bits behind. A clean flannel is simpler and safer.
Is a warm or a cold compress better for tired eyes?
They feel different rather than one being better. Warmth tends to feel relaxing, while something cool can feel refreshing after a long day. Pick whichever you find more comfortable.
Can I use a warm compress with contact lenses in?
No. Take your lenses out first. With a stye, the NHS goes further and suggests no lenses or eye make-up until it has healed.
Can I fall asleep with a warm compress on?
Best not. A damp flannel cools and gets cold, and heat packs are designed for a set time. Remove it before you settle down to sleep.
No Bowl, No Microwave?
Keep a box of Nyla Rest self-warming eye masks in a drawer or travel bag. Each box holds seven single-use masks that warm themselves the moment you tear the pouch, for a good half hour or more of gentle heat. They carry a light scent, and every fragrance ingredient is listed on the packaging. Spend more than £20 and we deliver free across the UK.

They are no substitute for medicine and are unsuitable for children. Skip them over sore or broken skin, and throw away any mask whose pouch is damaged.
