Blepharitis
Blepharitis is inflammation of the eyelid margins — the strip of skin and lash line where the lids meet. It is one of the most common eye conditions there is, one of the most persistently uncomfortable, and one of the most frequently dismissed. People are often told to use warm compresses and sent away. That advice is not wrong, but on its own it fails often enough that many people conclude nothing can be done.
Something can usually be done. What it takes is working out which kind of blepharitis you have, because the treatments are different and the wrong one will not work however diligently you apply it.
The two kinds, and why the difference matters
Anterior blepharitis affects the front of the lid margin, around the base of the lashes. It is driven by bacteria, by seborrhoeic skin change, or by Demodex mites living in the lash follicles. The signs are crusting and flaking at the lash base, redness along the lid edge, and in Demodex cases a characteristic collarette of waxy debris cuffing the lash.
Posterior blepharitis affects the inner lid margin, where the meibomian glands open. Glands that should produce clear oil for your tear film become blocked and inflamed, the oil thickens, and the tear film destabilises. This overlaps heavily with meibomian gland dysfunction and accounts for most of the long-running, treatment-resistant cases.
Most people have some of both. Treating only one is the usual reason treatment fails.
What it feels like
- Gritty, burning or sore lids, typically worst on waking
- Crusting or sticky lashes in the morning
- Red, thickened or itchy lid margins
- Watery eyes — a poor tear film triggers reflex tearing, so watery eye and dry eye are frequently the same problem
- Fluctuating or smeary vision that clears briefly when you blink
- Contact lenses that have become uncomfortable when they never used to be
- Recurrent styes or chalazia
Why it is worth taking seriously
Blepharitis is uncomfortable rather than dangerous, and it does not threaten sight. What it does do, quietly, is damage the meibomian glands over years of untreated inflammation. Glands that atrophy do not grow back. That is the argument for imaging the glands early rather than after a decade of warm compresses — not because the condition is an emergency, but because the part of it that is irreversible happens slowly and without symptoms.
What we do about it
Diagnosis at Rose uses high-magnification lid margin examination, meibography to image the glands themselves, objective tear film assessment and tear osmolarity, and gland expression to see what actually comes out. That combination is what separates “your eyes are dry” from a specific, treatable diagnosis.
Treatment is matched to the diagnosis rather than offered as a package, and includes in-clinic lid debridement, intense regulated pulsed light, thermal pulsation, prescribed medication where indicated, and lid hygiene taught properly rather than described.
For the full detail on assessment, each treatment and current pricing, see our blepharitis treatment page. If mites are the driver, BlephEx for Demodex and blepharitis covers that specifically.
Common questions about blepharitis
What causes blepharitis?
Rarely one thing. Anterior disease is usually bacterial overgrowth along the lash line, seborrhoeic skin change, or Demodex mites, which are present on most adults and become a problem when they proliferate. Posterior disease is a failure of the meibomian glands, driven by inflammation and by oil that has thickened until it cannot get out. Skin conditions travel with it — rosacea and seborrhoeic dermatitis both raise the risk considerably. It is not caused by poor hygiene, and people are often quietly worried that it is.
Can blepharitis affect my vision?
Not permanently, but it does affect vision moment to moment. An unstable tear film scatters light, which is why vision can be smeary and clears briefly after a blink, and why it is often worse late in the day or after screen work. Corrected properly, blepharitis does not cause lasting sight loss. If your vision is genuinely reduced rather than fluctuating, that is a different problem and needs examining.
Does blepharitis cause styes and chalazia?
It predisposes to both. A blocked gland that becomes infected is a stye; a blocked gland that becomes a firm painless lump is a chalazion. If you get either repeatedly, the underlying lid disease is usually the reason, and treating the lump without treating the lids is why they keep coming back.
Can children get blepharitis?
Yes, and it is under-recognised in children. It tends to present as recurrent styes, red lid margins, or a child who rubs their eyes constantly and is assumed to have allergies. Children respond well to treatment, and the earlier the inflammation is controlled the less gland damage accumulates.
Is blepharitis linked to rosacea?
Closely. Ocular rosacea and posterior blepharitis are largely the same disease process at the lid margin, and many people have significant lid involvement with only mild facial signs. If you have rosacea and gritty eyes, the two are almost certainly connected, and treating them together works far better than treating either alone.

Frequently asked questions
At Rose, a standard adult eye examination is $129. A new patient appointment takes 45 minutes, and imaging and a full pre-examination workup are included in that price rather than added afterwards. Children and school students are $79, tertiary students $99, and an acute appointment for a sudden problem — a red eye, a foreign body, a sudden change in vision — is $69. Where further testing is needed it is quoted before it is done: visual fields $69, macular OCT $69, full OCT $194, anterior segment OCT $39, corneal topography $59, optical biometry $49, cycloplegic refraction $59. Specialist appointments are priced separately. A keratoconus consultation is $139 for 30 minutes or $169 for 45. An ortho-k consultation is $129. A full dry eye evaluation, which produces a written treatment plan, is $247 — it assumes a current full eye examination, either with us ($129) or a full examination record from another practice within the last six months. Fees elsewhere in New Zealand vary widely, and a lower advertised price usually means a shorter appointment with imaging charged as an extra or not offered at all. It is worth comparing what is included rather than the headline number. Ring us on 07 847 3195 if you want the fee for your situation confirmed before you book.
No practice can honestly claim that, and you should be wary of any that does — "best" depends entirely on what your eyes need. If your eyes are straightforward, several good practices in Hamilton will look after you well, and we would rather say that than pretend otherwise. What separates practices is what they can measure, and what they can treat when things are not straightforward. Rose was built around the complicated end. The Rose K lens for keratoconus was designed in this practice, and lenses of that family are, on the manufacturer's figures, among the most widely prescribed in the world for the irregular cornea. We hold swept-source OCT, corneal tomography, epithelial thickness mapping, two independent optical biometers for monitoring a child's short-sightedness, and objective tear film assessment. For dry eye we hold intense regulated pulsed light, LipiFlow, Blephasteam, Tixel and Rexon-Eye — to the best of our knowledge no other practice in New Zealand has all of these under one roof. A better question than "who is best" is "who is set up for what I have". Ask any practice you are considering how long the appointment is, what they can measure, and whether imaging is included or extra. Those answers will tell you more than a ranking would.
Not usually as a full examination, but there are genuinely free and subsidised pathways worth knowing about. Pre-school children are screened free through the B4 School Check, and there is vision screening in schools. Both are screenings rather than eye examinations — they are designed to catch obvious reduced vision and they miss a great deal, including focusing problems and early short-sightedness. A child who passes a screening can still need glasses. Children under 16 whose family holds a Community Services Card, or who hold a current High Use Health Card, may be eligible for the government spectacle subsidy towards an examination and glasses. MSD criteria apply, and we accept MSD and WINZ payment cards. Southern Cross members can use their optical benefits with us, and we offer Afterpay, Genoapay, QCard and GoCardless. We also run two free 15-minute chats. The myopia chat is for parents of a short-sighted child who want the options explained and want help deciding what is actually right for their family, with our experience behind that decision rather than a brochure. The ortho-k chat is for anyone considering overnight lenses who wants to understand what is involved before committing. Neither is an eye examination, but both are a proper conversation with someone who does this work. If cost is the reason you have been putting off having your eyes checked, ring us on 07 847 3195 and say so. We would rather find a way than have you not come.
While payment is generally required on the day of appointment, we do offer a number of payment options including Afterpay, Genoapay, QCard, and GoCardless.
No. We are closed on public holidays and long weekends as we believe our staff should have the chance to enjoy this time with friends and family.
If your eyes are straightforward, almost any good optometrist can look after you well, and we would rather say that than pretend otherwise. Come to us when something is not straightforward: a prescription that will not settle, a cornea that has changed shape, a child whose short-sightedness is moving faster than it should, an eye surface that has stopped being comfortable, or a diagnosis you have been given but do not understand. Those problems are decided by measurement, and measuring them properly needs instruments most practices do not have.
Yes, and you do not need to justify it. A second opinion is not a criticism of whoever saw you first — very often they were right, and what you actually needed was the finding explained and the numbers put in front of you. What we can add is measurement. We can image the layers of your cornea and retina, map the epithelium, quantify how far your cornea sits from normal, measure the length of your eye and check your tear film objectively. That turns “something is not right” into a number, and a number either explains the problem or rules it out. Bring any previous scans, prescriptions and letters. Comparison against your own past results is often the most valuable thing in the room.
Usually. Complex is what this practice was built around — keratoconus, corneal grafts, irregular corneas after surgery or injury, severe dry eye, high prescriptions, and eyes that have been told they are not fittable with contact lenses. The Rose K lens for keratoconus was designed in this practice, and lenses of that family are, on the manufacturer's figures, among the most widely prescribed in the world for the irregular cornea. If we cannot help, we will tell you at the first appointment and tell you who can, rather than taking you through a course of treatment that was never going to work.
Waiting is the one thing that cannot be undone. Short-sightedness is axial — the eye is physically growing too long — and that length does not come back. What treatment does is slow the rate of growth, so the earlier it starts the more length is saved. We measure axial length directly on two independent biometers and plot it against normal growth curves, which means we can see a child drifting off their expected curve before the prescription changes. There is a free 15-minute myopia chat if you want to understand the options before committing to anything. It is worth being precise about what we are all trying to achieve. Myopia control does not stop a child's eyes changing and no practice should tell a parent it will. What it does, reliably and across many published trials, is slow the rate at which the eye lengthens — and because the risk of retinal detachment, myopic maculopathy and glaucoma in later life rises with every extra millimetre, slowing that growth is how a child is kept out of the range where sight is genuinely at risk. After seventeen years of focusing on this, we are now seeing children on customised plans whose axial length is not progressing at all over a monitoring period, and in some cases measurements that come back slightly shorter than the ones before them. That is our own clinical observation in our own patients rather than a trial result, and it has to be read carefully, because the choroid thickens when treatment is working and part of an apparent reduction can be that thickening rather than the eye itself shortening. That is precisely why we measure both. We are not yet able to tell a parent that we can stop myopia in its tracks, and we will not say it until we can.
Two things: we measure it before treating it, and we hold every current treatment technology in one building. Most dry eye is treated on the basis of symptoms, which is why drops so often fail. A tear film can be failing because the oil layer is blocked, because the water layer is short, because the surface is inflamed, or because the lids are the problem, and those need different treatments. We assess the tear film objectively with TearCheck — tear film stability, the oil layer, lid and gland imaging, and an inflammation measure — and measure tear osmolarity, the saltiness of the tears, which is the closest thing to a laboratory number for dry eye. Then we treat the cause. Rose holds intense regulated pulsed light for inflammation and gland function, LipiFlow thermal pulsation to clear blocked meibomian glands from the inner lid surface, Blephasteam controlled-humidity warming, Tixel thermomechanical treatment for the lids, and Rexon-Eye quantum molecular resonance for the more severe and treatment-resistant cases. At the time of writing, and to the best of our knowledge, no other optometrist or ophthalmologist in New Zealand has all of these available under one roof. We say that as a statement of fact rather than a boast, and we would be glad for it to stop being true. Dry eye is one of the most common and most under-treated conditions we see, and there are far more people living with it than one practice can look after. Any practice wanting to build this kind of service has our encouragement and our help — please contact us for co-management, and send us the cases you are not yet set up for. Why holding all of them matters is simple. A practice with one dry eye machine will offer you that machine. Holding all of them means the assessment decides the treatment, rather than the equipment deciding it — and when the first approach does not work, the next one is in the next room rather than in another city.
Yes — from around six weeks of age. Babies and toddlers are tested with Cardiff acuity cards and retinoscopy, neither of which needs the child to read a letter, name a picture or say a word. Most of the findings that matter in a young child cause no symptoms and are invisible to a parent, which is exactly why they need looking for.
In NZ an optometrist can calculate the prescription for glasses, fit contact lenses, diagnose and treat eye conditions and infections with medication. They can also manage ocular injuries including removing foreign objects. If surgery or specialist treatment is required they can refer to an ophthalmologist (eye surgeon), hospital, or other health care specialist. NZ-trained optometrists must complete a 5-year degree at the University of Auckland before becoming registered.
A dispensing optician has formal training in optical dispensing. They are qualified to help a client choose frames, read a prescription, discuss lens options, take measurements, order and fit glasses.
An ophthalmologist is a medical doctor who has specialised in the treatment of serious eye disease and ocular surgery such as cataract removal. They do not typically prescribe glasses or contact lenses.
Not always, and the difference is usually time and instruments rather than the optometrist. A low advertised fee generally buys a shorter appointment aimed at producing a spectacle prescription. That is a legitimate service and for many people it is enough. What it often does not include is retinal imaging, OCT scanning of the optic nerve and macula, measurement of eye length, or objective assessment of the tear film — the tests that find glaucoma before you notice it, detect macular change early, monitor a child's short-sightedness properly, or explain why your eyes feel gritty. At Rose a new patient appointment is 45 minutes, and imaging and the full pre-examination workup sit inside the $129 rather than on top of it. We are not the cheapest and do not try to be. Whichever practice you choose, three questions are worth asking: how long is the appointment, is imaging included or charged separately, and what happens to the images afterwards. A scan that is taken and kept becomes the baseline every future scan is compared against, and that comparison is frequently worth more than any single result.
Start with an optometrist in almost every case. An optometrist is your first point of contact for eye health and vision — examining the eyes, prescribing glasses and contact lenses, diagnosing eye disease, and in New Zealand treating many conditions with prescription medicines. An ophthalmologist is a medical doctor and eye surgeon who treats serious disease and performs surgery such as cataract removal, and who does not usually prescribe glasses or contact lenses. Neither is better than the other; they do different jobs. Most eye problems are diagnosed and managed by an optometrist, and where surgery or specialist medical treatment is needed we refer you promptly and stay involved in your care. The exception is anything sudden and severe: sudden loss of vision, a curtain across your vision, severe eye pain with a red eye, or a shower of new floaters and flashes. Phone us on 07 847 3195 rather than booking online — a person, not a calendar, decides how quickly you are seen — or go to hospital.
We are at 38 Lake Road in Frankton, with parking on site, a few minutes from the city centre and straightforward to reach from the western side of Hamilton. Our patients come from right across the city — Frankton, Dinsdale, Nawton, Te Rapa, Glenview, Hamilton East, Hillcrest, Chartwell, Rototuna and the central city — and from across the wider Waikato, including Cambridge, Te Awamutu, Morrinsville, Matamata, Huntly, Ngaruawahia, Otorohanga and Raglan. Because much of what we do is specialist work, a good number travel considerably further. We regularly see patients from Auckland, Tauranga, Rotorua, Taupo, Taranaki and the lower North Island for keratoconus, scleral and custom contact lens fitting, and complex dry eye — and we see patients from overseas who combine treatment with a trip. If you are travelling a distance, tell us when you book and we will group your appointments so the journey is worth making.
Forty-five minutes for a new patient, and the appointment is built so the measuring is done before you sit down with the optometrist. A full pre-examination workup and imaging are included in the fee rather than charged on top: assessment of your vision and prescription, examination of the front and back of the eye, eye pressure, and retinal imaging that becomes your permanent baseline. You will leave knowing what we found, what it means, and what — if anything — needs doing. If the honest answer is that nothing needs doing, that is what you will hear. If something needs watching or treating, you get a clear plan and a review date. Where a specific problem needs a specific test — visual fields, OCT, corneal topography, eye length measurement — those are quoted to you before they are done, never added afterwards without your agreement. Existing patients returning for a routine examination are booked for 30 minutes. Please arrive ten minutes early, and bring your current glasses or contact lenses, any recent prescription or referral letter, and a note of the medications you take, because some affect the eyes.
