Blepharitis: How to treat it and stop it coming back
If your eyelids feel sore, itchy or crusty in the morning and it keeps coming back no matter what you do, there's a good chance you're dealing with blepharitis.
It's one of the most common conditions I see as an optometrist. I'd estimate in 20 years I've discussed blepharitis with patients thousands of times, and the conversation almost always goes the same way. They've been told to "keep the lids clean," they've tried it for a fortnight, nothing much happened, and they gave up.
That's the real problem with blepharitis; not that it's hard to treat, it's that it's easy to treat badly. Here's what actually works, why most people get it wrong, and what a realistic daily routine looks like.
What is blepharitis?
Blepharitis simply means inflammation of the eyelid margins — the thin strip of skin right at the base of your lashes where your eyelids meet.
It isn't an infection you catch, it isn't contagious, and it isn't dangerous to your sight. But it is chronic, meaning it's a condition you manage rather than one you cure. The NHS, Moorfields and the College of Optometrists all describe it the same way: symptoms can be controlled very well, but the underlying tendency doesn't disappear.
That single fact explains almost every treatment failure I see. People treat blepharitis like a chest infection — do the course, expect it gone. It behaves far more like dandruff or eczema: manage it consistently and it stays quiet; stop, and it comes back.
The three types
Anterior blepharitis: affects the front of the lid margin, around the base of the lashes. It's usually linked to bacteria on the skin or to seborrhoeic dermatitis (the same process behind dandruff). Classic sign: crusting and flakes clinging to the lashes, worst first thing in the morning.
Posterior blepharitis: affects the back edge of the lid, where the meibomian glands open. These are the tiny oil glands that keep your tears from evaporating. When they clog, you get posterior blepharitis, and it overlaps almost completely with meibomian gland dysfunction (MGD). Classic signs: burning, gritty eyes that worsen through the day, and eyes that water for no reason.
Mixed blepharitis: is both at once — and honestly, this is what most people actually have.
Why does the type matter? Because it changes the emphasis. Anterior blepharitis responds best to thorough cleaning. Posterior blepharitis responds best to heat (cleaning alone barely touches it). Most people need both, and most people only do one.
What causes blepharitis?
There's rarely a single cause. The usual contributors are:
Skin conditions — seborrhoeic dermatitis and rosacea are strongly associated with blepharitis. If you have dandruff or facial flushing, that's a meaningful clue.
Meibomian gland dysfunction — the oil in the glands thickens (think butter straight from the fridge) and stops flowing properly. I've written about this in detail in my guide to meibomian gland dysfunction.
Bacteria on the lid margin — normal skin bacteria that overgrow when the lid isn't being cleared properly.
Demodex mites — microscopic mites that live in the lash follicles. They're present on most adults harmlessly, but overgrowth can drive stubborn blepharitis, particularly the sort that resists ordinary treatment.
Age — gland function tends to decline over time.
Eye make-up and heavy eyeliner - particularly waterline application, which blocks the gland openings directly.
Blepharitis, dry eye or MGD — what's the difference?
These three get muddled constantly, even by clinicians, because they overlap so heavily.
Blepharitis is inflammation of the eyelid.
MGD is a failure of the oil glands in the eyelid.
Dry eye is what your eye surface experiences when the tear film stops working.
The chain usually runs one way: blepharitis or MGD comes first, the tear film destabilises, and dry eye symptoms follow. Which is why treating dry eye with drops alone often disappoints, you're managing the symptom while the cause carries on unchecked.
A useful rule of thumb: if your symptoms are worse when you wake up, that points towards the eyelids. If they're worse at the end of the day (especially after screens) that points towards the tear film. Most people report both.
Symptoms of blepharitis
Red, swollen or sore eyelid margins
Crusting or flakes at the base of the lashes, worst on waking
Itchy or burning eyelids
Gritty eyes, like sand or an eyelash you can't find
Eyes that water excessively (yes — watery eyes are frequently dry eyes; the eye floods itself with poor-quality reflex tears to compensate for the dryness)
Blurred vision that clears when you blink
Eyelids sticking together in the morning
Contact lenses becoming less comfortable than they used to be
When to get it checked
See an optometrist or your GP promptly if you have pain in the eye itself (rather than the lid), any loss of vision, significant light sensitivity, or a painful lump on the lid that's growing. Those aren't ordinary blepharitis and need looking at properly!
How to treat blepharitis at home: the daily routine
This is the part that matters; three steps (five to ten minutes), done in this order, because the order is what makes it work.
Step 1 — Heat (3–5 minutes)
Warm the lids first. Heat softens the thickened oil in the meibomian glands so it can actually be moved. Skipping straight to cleaning is like trying to wash a greasy pan in cold water.
The key is sustained heat. A flannel under the hot tap feels lovely for about forty seconds and then it's colder than your skin — which is why it doesn't work, and why so many people conclude warm compresses are useless. You need a consistent temperature held for several minutes, which is what a microwavable heated eye mask is designed to do.
Close your eyes, rest the mask across both lids, and leave it there for at least 3-5 minutes.
Step 2 — Massage (30 seconds)
Immediately after the heat, while the oil is still soft, gently massage the lids to express it.
Using a clean fingertip, roll gently towards the lash line — downwards on the upper lid, upwards on the lower lid. You're encouraging oil out of the glands, not scrubbing. Firm but gentle. Never press hard on the eyeball itself.
Step 3 — Clean (1 minute)
Now clean the lid margin — the base of the lashes specifically, not the eyelashes themselves and not the surrounding skin. This is where nearly everyone goes wrong: they wash their face, feel virtuous, and never touch the actual lid margin.
Pull the lid gently taut, look away from the side you're cleaning, and wipe along the lash base in short strokes. Use a dedicated eyelid cleanser or lid wipe, which is formulated for the eye area and pH-appropriate.
A note on baby shampoo: it's the traditional advice and you'll still see it on plenty of leaflets. But dedicated lid cleansers were developed precisely because diluted shampoo can strip the delicate lipid layer and irritate the eye surface in some people.
Step 4 (as needed) — Lubricate
If the eye surface itself feels gritty or sore, preservative-free lubricating drops help settle symptoms while the routine does the underlying work. Drops don't treat blepharitis — they make living with it more comfortable, which matters when you're a fortnight into a routine and waiting for results.
How long until it improves?
Give it six weeks of daily practice before you judge it.
I know that sounds long. Most people abandon the routine somewhere in week two, exactly when they'd be starting to notice a change. Realistically:
Week 1–2: little obvious change. Sometimes mild irritation as you start handling the lids.
Week 3–4: mornings become easier. Less crusting, less stickiness.
Week 6–8: noticeably calmer eyes, fewer flare-ups, more comfortable days.
Then the important bit: don't stop. Once things settle, most people can drop to a maintenance level: heat and clean a few times a week rather than daily, and step back up to daily whenever a flare starts. If you stop completely, it typically returns within a few weeks!
Will blepharitis ever go away?
Straight answer: no, not permanently.
But that's a far less depressing sentence than it first appears. Blepharitis responds genuinely well to management. Patients who commit to a routine typically go from constant daily irritation to occasional mild flare-ups that they can shut down quickly. That's a real, meaningful change in quality of life.
The mental shift that helps most is this: stop thinking of it as a problem you're solving and start thinking of it as a small piece of daily maintenance, like brushing your teeth.
Demodex blepharitis: the stubborn kind
If you've done everything above consistently for two months and seen almost no change, demodex mites are worth considering.
The distinguishing sign is collarettes — small waxy cuffs wrapped around the base of individual lashes, which look different from ordinary flaky crusting. They're best seen by an optometrist at the slit lamp, so it's worth booking an examination rather than diagnosing yourself in the bathroom mirror.
Management centres on lid hygiene using products containing tea tree oil (specifically its active component, terpinen-4-ol), which mites dislike. Important safety point: never apply neat tea tree oil near your eyes — it's a strong irritant and can cause real damage. Use only a properly formulated eyelid product.
You may come across references to a prescription drop called XDEMVY (lotilaner). It was approved by the FDA in the United States in 2023 and works by directly targeting the mites. It is not licensed in the UK, so it isn't available here through the NHS or private practice.
I'll cover demodex in much more depth in a dedicated article shortly.
What the NHS offers vs what you can do yourself
NHS advice for blepharitis is essentially the routine above: warm compress, massage, lid hygiene, done consistently at home. That advice is correct — it's the evidence-based first-line treatment, and there's no secret alternative being withheld.
Where the NHS steps in beyond that is for complications: antibiotic ointment or oral antibiotics for persistent bacterial involvement, treatment of an associated skin condition like rosacea, or management of a stye or chalazion.
What NHS advice doesn't generally give you is the practical detail — how long to hold the heat, what temperature, which part of the lid to clean, what to use, how long before you'll notice anything, and what to do when it comes back. That knowledge gap is exactly where most treatment failures happen, and it's why I have written this article.
The mistakes I see most often
After two decades of these conversations, the same handful come up again and again:
Cleaning without heating: Cold cleaning barely shifts thickened oil - Heat first, always.
Using a flannel and calling it a warm compress: It cools within a minute. It's not doing the job you think it's doing.
Cleaning the eyelashes but not the lid margin: The lash base is the target. Everything else is just washing your face.
Stopping too early: Two weeks isn't a trial, Six weeks is a trial.
Stopping when it works: Understandable, and the reason for most "it came back" stories.
Scrubbing too aggressively: More force isn't more effective — inflamed lids respond badly to trauma. Gentle and consistent beats hard and sporadic every time.
Relying on drops alone: Drops soothe the surface, they don't unblock a gland or clear a lid margin.
Frequently asked questions
Is blepharitis contagious?
No. You can't pass it to your partner, your children or anyone else. It's an inflammatory condition of your own eyelid margins, not an infection you spread.
Can I wear make-up if I have blepharitis?
Yes, but be selective. Avoid applying eyeliner to the waterline — that's exactly where the meibomian gland openings sit, and blocking them directly makes matters worse. Remove all eye make-up thoroughly each night, replace mascara every three months, and skip make-up entirely during an active flare-up.
Can I still wear contact lenses?
Usually yes, though blepharitis often makes lenses less comfortable. Do your lid routine before inserting lenses, never after. If your eyes are genuinely inflamed, give them a break in glasses for a few days until things settle, and mention it at your next contact lens check.
How often should I do the routine?
Daily while symptomatic. Once symptoms settle, three or four times a week as maintenance, returning to daily at the first sign of a flare-up.
Baby shampoo or a dedicated cleanser?
A dedicated eyelid cleanser is formulated for the eye area and is gentler on the tear film. Avoid diluted Baby shampoo as it can irritate some people and strip the natural lipid layer.
Does diet make a difference?
Some evidence suggests omega-3 intake may support meibomian gland function, though results across studies are mixed. It's a reasonable addition, not a replacement for the routine.
How do I know whether it's blepharitis or something else?
Book an eye examination. An optometrist can look at your lid margins under magnification and tell you within moments what type you have, whether collarettes are present, and how your glands are functioning — which is far more useful than guessing from a mirror.
