Blepharitis
Blepharitis is chronic inflammation of the eyelids — the red, crusty, itchy, or burning lids that never quite settle down. It's extremely common, closely tied to dry eye, and very manageable once the type and cause are identified. Care is available at our Newton, MA office, serving Needham, Wellesley, Brookline, Waltham, and Greater Boston.
Two forms of blepharitis
Anterior blepharitis
Affects the front of the lid, at the base of the eyelashes. Usually from skin bacteria, Demodex mites, or seborrheic (dandruff-type) skin. Tends to cause crusting and flaking on the lashes.
Posterior blepharitis
Affects the inner lid and the meibomian oil glands. Overlaps closely with meibomian gland dysfunction (MGD) and evaporative dry eye.

What is blepharitis?
Blepharitis simply means inflammation of the eyelids, usually along the lid margin where your eyelashes and oil glands are. It's one of the most common conditions eye doctors see, and it tends to be persistent — flaring up and calming down rather than disappearing for good.
It matters because the eyelid margin is where your tear film gets its oil. When the lids are inflamed, crusted, or colonized by bacteria or Demodex mites, that spills over into the eye surface — which is why blepharitis so often travels together with MGD and dry eye, and why treating the lids usually improves comfort overall.
The good news: once we identify whether it's anterior, posterior, or Demodex-related, blepharitis responds well to a targeted routine — and it's not contagious.
Symptoms of blepharitis
Symptoms are often worst in the morning and can come and go in flares.
Red, swollen lid margins
Eyelid edges that look inflamed, pink, or thickened.
Crusting & flaking
Dandruff-like debris or scales clinging to the base of the lashes.
Itching & burning
An urge to rub, with stinging or burning along the lash line.
Stuck-together lids
Eyelids that feel glued or crusted shut on waking.
Recurrent styes & chalazia
Repeated lid bumps as oil glands block and become inflamed.
Gritty, watery eyes
A foreign-body feeling and reflex tearing as the eye surface is irritated.
What causes blepharitis?
Blepharitis usually has more than one contributor working together:
- Skin bacteria. An overgrowth of the bacteria that normally live on the lids produces irritating byproducts.
- Demodex mites. Microscopic lash mites cause a specific form of anterior blepharitis marked by collarettes. See Demodex-focused lid care.
- Skin conditions. Seborrheic dermatitis (dandruff) and rosacea inflame the lid margins.
- Blocked oil glands. MGD underlies most posterior blepharitis.
- Incomplete blinking. Long screen sessions reduce how well the lids clear and express oil.
- Makeup & hygiene. Eye makeup residue and infrequent lid cleaning let debris build up.
How blepharitis is diagnosed
Diagnosis is quick and painless. Under high magnification at the slit lamp, Dr. Patel examines the lid margins, lash bases, and oil-gland openings — looking for redness, crusting, the pattern of any flakes, and whether the meibomian glands are blocked.
The details matter because they point to the cause. Collarettes — cylindrical flakes wrapped around the lash base — signal Demodex mites. Greasy scales suggest seborrheic blepharitis. Thick, blocked oil points to posterior blepharitis and MGD. That's what lets treatment be targeted rather than one-size-fits-all.
Signs we look for
- Collarettes — cylindrical flakes at the lash base, the hallmark of Demodex.
- Greasy or dry scales along the lashes, pointing to seborrheic or staph blepharitis.
- Blocked, capped oil glands — the sign of posterior blepharitis and MGD.
How blepharitis is treated
Consistent lid care is the foundation. When that isn't enough, in-office treatments target the specific cause.
Lid hygiene & warm compresses
Daily warmth plus gentle lid cleaning loosens crust, clears debris, and keeps flares down. The cornerstone of every plan.
NuLids PRO
Micro-exfoliation that clears the lash margin of debris, biofilm, and Demodex — deeper than a cotton swab can reach.
Learn about NuLidsOptiLight IPL
Light therapy that calms lid-margin inflammation — especially helpful when rosacea or MGD is part of the picture.
Learn about IPLTargeted medical therapy
When needed, prescription treatments address bacteria, Demodex, or inflammation directly — matched to your type of blepharitis.
Because blepharitis is chronic, the aim is a simple routine you can keep up — so flares become rare and mild.
Common Questions
What patients ask most about blepharitis.
Is blepharitis contagious?
No. Blepharitis isn't contagious — it's an inflammatory condition of your own eyelids, not an infection you catch from or pass to others. It's driven by things like bacteria that normally live on the skin, Demodex mites, blocked oil glands, and skin conditions such as rosacea and dandruff.
Can blepharitis be cured?
Blepharitis is usually a chronic condition, so the goal is to control it rather than cure it once and for all. With a consistent lid-hygiene routine and, when needed, in-office treatment such as NuLids or IPL, most people keep symptoms well managed. Flare-ups can happen if the routine lapses, which is normal and manageable.
What's the difference between blepharitis and dry eye?
Blepharitis is inflammation of the eyelids; dry eye is instability of the tear film on the eye surface. They're tightly linked — posterior blepharitis involves the meibomian glands, so it's a common cause of evaporative dry eye, and the two often occur together. Treating the eyelids frequently improves dry eye symptoms as well.
How do I get rid of blepharitis at home?
The foundation is daily lid hygiene: warm compresses to loosen oils and crust, followed by gentle cleaning of the lash margins with a lid cleanser. Consistency matters more than intensity. If symptoms persist despite home care, an evaluation can identify the type of blepharitis and add in-office treatments like NuLids micro-exfoliation or IPL.
Is blepharitis caused by Demodex mites?
Sometimes. Demodex mites are a common cause of anterior blepharitis, especially when there are cylindrical flakes (collarettes) wrapped around the lash bases. Demodex-related blepharitis is treated differently from other forms, which is why identifying the cause matters. It's one of several possible drivers, alongside bacteria, seborrheic skin, and meibomian gland dysfunction.
