Dry, Gritty Eyes? Start Here — The Rose Optometry Dry Eye Pathway

Dry, gritty, tired, watery, burning eyes. Vision that smears and clears when you blink. Worse by evening, worse on screens, worse in air conditioning and wind.

If that's you, this page is the whole pathway in order — what to try first, how long to give it, how to tell whether it's working, and what changes when we measure rather than guess.

Most people can make real progress on step one alone. The people who can't are usually the people who most need step two.

Step 1 — Start here. You should notice a difference within two to three weeks.

Almost all dry eye has two components: the lid margin, where the oil that stops your tears evaporating is produced, and the tear film itself. Treating one without the other is why so many people feel a drop "stopped working."

So the starting routine treats both.

The starter kit

1. Clean the lid margin — OCuSOFT HypoChlor, once a day.

Hypochlorous acid is the same compound your own immune cells produce. As a lid spray it reduces the bacterial and debris load along the lash line without scrubbing an already sore surface.

Close both eyes, spray both lids, and leave it. No rinsing, no rubbing, no wiping it off. Once daily is enough.

This is the step people skip, and it's the one that changes the trajectory.

2. Lubricate regularly — Avizor Lacrifresh Moisture, three times a day.

Preservative-free hyaluronic acid. Three times daily, every day, whether or not your eyes feel bad that morning — this is the part that has to be routine rather than reactive. Dosing only when you're already uncomfortable is treating symptoms after the surface has already been stressed.

3. Add one targeted drop, chosen by what your eyes actually do:

  • If your eyes water — genuinely stream, especially in wind or by the end of the day — use Systane COMPLETE. Watering eyes are usually evaporative dry eye: the surface dries, the eye panics and floods itself with watery tears that have no oil in them and evaporate just as fast. Systane COMPLETE is preservative-free and formulated to address the oil side as well as the water side. Counter-intuitive, but watering eyes need a better tear film, not less tear volume.

  • If your lids are red, itchy, crusted or inflamed — use Optimel Antibacterial Manuka Honey Eye Drops instead. Medical-grade manuka honey has an antibacterial and anti-inflammatory action that suits an inflamed lid margin.

It stings. That is the mechanism, not a side effect. It's a hyperosmotic product and the sting is it working. Start once a day, build up as you tolerate it. Nobody who's warned about this stops; almost everybody who isn't stops on day two.

4. Heat, properly — at least 10 minutes, once daily.

This is the step most people get wrong, and it's the one that does the heavy lifting. The oil in your glands has to be warmed before it will move, and the target is a lid temperature of at least 40°C, held for at least 10 minutes, once daily. Those are the figures a 2024 evidence review in Ophthalmology and Therapy settled on: multiple studies converge on 40°C as the threshold for therapeutic effect, and once daily is recommended deliberately over anything more frequent, because adherence falls as the frequency rises. In MGD the thickened meibum often melts above body temperature (37°C) — which is why your own body heat never clears a blocked gland. And a facecloth from the hot tap holds the lid above 40°C for only the first minute and is below target within about two minutes — you would have to reheat it every two minutes to keep it there, which is why almost nobody succeeds with one. You need sustained, controlled heat.

Then massage. Roll a clean fingertip from the base of the lid towards the lashes — upper lid downwards, lower lid upwards. Heating without expressing softens the oil and leaves it exactly where it was.

Order matters: heat → massage → clean the lid margin → drops.

The kits

We've packaged these so you don't have to work out quantities:

→ Complete Dry Eye Kit — heat, lids and drops together. The full routine, and what we'd recommend if you're starting from scratch.
→ Dry Eye Starter Kit — Watery Eyes — if you already own a compress.
→ Dry Eye Starter Kit — Irritated Lids — the Optimel version, for inflamed lid margins.

All three cost less than buying the items separately, and all qualify for free NZ shipping.

5. Retrain your blink — free, and more important than it sounds.

In healthy eyes, 80–90% of blinks are complete — the lids actually touch. Computer use drops the blink rate by 40–50%, and the blinks you do manage become partial. That matters more than most people expect: a high proportion of partial blinks is associated with roughly double the rate of dry eye disease, and incomplete blinkers show measurably greater meibomian gland loss. If the lids never fully close, the lower portion of the glands never gets expressed — and no drop compensates for that.

The good news is that blinking is a trainable, muscular action. Here's the exercise we give patients:

  1. CLOSE — teach the lids to touch
  2. PAUSE for a count of 2 — reinforce the lids touching
  3. SQUEEZE down lightly for a count of 2 — develops the muscles and stimulates the neural pathways controlling the downward phase of the blink
  4. OPEN for a count of 2 — completes the sequence

Repeat for 10 repetitions. Do those 10 reps every hour, at least 10 times a day, every day.

Use our app to remind you. We developed Think to Blink for exactly this — it has a reminder function that prompts you through the exercises so you don't have to keep track.

Also worth doing, and free: move air away from your face. Car vents, heat pumps, desk fans and CPAP leaks are all common causes and all fixable.

Do all of it, every day, for two to three weeks

That's the window. Done properly and consistently, this routine produces a noticeable improvement within two to three weeks for most people.

It won't produce it in three days, which is where most people give up — lid and gland changes take a couple of weeks to show. But equally, if you've done all five steps properly every day for three weeks and nothing has shifted, that's your answer and it's a useful one. Don't push on to week eight hoping.

Step 2 — At two to three weeks, one of two things has happened

You're better

Good — that tells us something useful. Keep going. Dry eye is managed rather than cured, and the routine that got you here is the routine that keeps you here. Most people settle into HypoChlor once daily and lubricants as needed.

This is still the right moment to book a full examination and dry eye assessment, and here's the honest reason: feeling better tells us your symptoms improved. It doesn't tell us whether the underlying cause is stable, whether your meibomian glands are structurally intact, or whether you're managing a condition that's quietly progressing. Symptoms and signs correlate poorly in dry eye — plenty of people feel fine with significant gland loss, and plenty feel terrible with healthy-looking lids.

A baseline measured while things are good is far more useful than one taken in crisis.

You're not better, or only slightly

Then stop buying bottles. Book the assessment. Another drop is not the answer, and the honest position is that we can't tell you why from here.

Three weeks of proper lid care, heat, blink training and preservative-free lubricants is a real therapeutic trial. If it hasn't worked, that's genuinely informative — it means something is driving your dryness that this routine doesn't reach, and the only way to find out what is to measure it.

If you're using lubricants several times a day and still uncomfortable, the drop isn't the problem — the diagnosis is.

Step 3 — The full examination and dry eye assessment

This is where we stop guessing and start measuring. A standard eye test checks your vision and eye health. A dry eye assessment is a different appointment with different equipment, and its purpose is to work out which mechanism is driving your symptoms — because the treatments diverge sharply from there.

What we measure, and why each one matters

Tear osmolarity (TearLab). We take a sample of tears smaller than a pinhead — 50 nanolitres — and measure how salty it is. As the tear film destabilises, it concentrates, and that rising saltiness is the thing that irritates and inflames the ocular surface. It's one of the core markers of tear film homeostasis in the international TFOS DEWS II framework.

Two numbers matter: the value itself, and the difference between your two eyes. A large gap between eyes points to an unstable film even when each individual reading looks acceptable. Because it's a number, it's also one of the few things we can track objectively across visits — you can watch treatment working rather than trying to remember whether March felt worse than June.

Meibography — imaging the oil glands. Infrared imaging of the glands inside your eyelids, showing their actual structure: full-length and healthy, shortened, twisted, or dropped out entirely.

This is the single most decision-changing test we do, because it separates two situations that feel identical to the patient. Glands that are blocked but structurally intact have a good outlook — clear them and function returns. Glands that have dropped out don't grow back, and the goal shifts to protecting what remains. Same symptoms, completely different conversation about the future, and you cannot tell which is which without looking.

It's also the image that makes people take the routine seriously. Nothing motivates daily lid hygiene like seeing your own glands on a screen.

Dye testing — fluorescein and lissamine green. A drop of dye and a blue light reveals what's invisible otherwise:

  • Tear break-up time — we watch how many seconds your tear film stays intact after a blink. Healthy is around ten or more. Under five tells us evaporation is the driver.
  • Corneal staining — fluorescein pools in damaged surface cells, showing where and how much the cornea has been affected, and graded so it can be compared visit to visit.
  • Lissamine green stains the conjunctiva and lid margins, including lid wiper epitheliopathy — friction damage to the strip of tissue that sweeps your eye with every blink. This is frequently positive in people who are genuinely symptomatic but whose eyes look unremarkable, and it's a common reason someone has been told "there's nothing wrong" elsewhere.

TearCheck — the non-invasive workup. Our ocular surface analyser measures what dye testing can't, without touching the eye: non-invasive break-up time, the height of the tear reservoir along your lower lid, the thickness and quality of the lipid layer, a map of ocular surface inflammation, and an analysis of how completely you actually blink. Incomplete blinking is far more common than people realise — if the lid never fully closes, the lower third of the glands never get expressed, and no drop will fix that.

Alongside these, depending on what the picture suggests: a standardised symptom score so your own experience is tracked as data rather than recollection, gland expression to judge the quality of the oil actually coming out, tear volume testing, examination of the lash bases for Demodex, and assessment of lid position and overnight closure — a genuinely common and very treatable cause of eyes that are worst on waking.

Between TearCheck, meibography and TearLab, we run one of the more complete dry eye diagnostic suites in New Zealand. That isn't a boast for its own sake — it matters because dry eye has several distinct mechanisms that produce identical symptoms, and the only way to treat the right one is to measure which it is.

How to book — and yes, the first one is free

Start with a free Dry Eye Evaluation. Fifteen minutes with one of our optometrists to work out why your eyes are dry or watery, talk through what's causing it, and lay out your options — from conservative measures right through to comprehensive in-office therapy. There is no charge for this appointment and no obligation to go further.

→ Book a free Dry Eye Evaluation · 15 minutes · no cost

If you'd rather go straight to the full picture — a complete examination of your vision and eye health alongside the dry eye workup — book a full examination instead. It runs 45 minutes for new patients, and it's the appointment where the whole diagnostic suite comes into play.

→ Book a full examination (new patients) · 45 minutes

Either way, please arrive ten minutes early for pre-examination testing.

You'll leave with your numbers, your gland images, an explanation of which mechanism is driving your symptoms, and a plan.

Step 4 — The tailored plan

Once we know the mechanism, the plan stops being generic. At home, that means a drop matched to whether your problem is evaporation, volume or inflammation; a lid programme set at an intensity the meibography justifies rather than a one-size routine; a six-week Demodex course if the lash bases call for it; and dealing with the contributors — medications that dry you out, incomplete blinking, overnight lid closure, allergic disease, screens, air, omega-3 status.

And where the assessment supports it, treatments you can't do at home.

In-practice treatments

We hold what is, as far as we know, one of the most complete dry eye treatment suites in the country. Each of these does something specific — which is the point of measuring first, because the wrong device on the wrong mechanism is money and time spent for nothing.

BlephEx — lid margin exfoliation. A medical-grade micro-sponge spun along the lash line to remove biofilm, scurf and the crust that ordinary cleaning can't shift. Where there's heavy anterior deposit or Demodex debris, this clears the ground so home lid hygiene starts working. Quick, done in the chair.

Blephasteam 2 — controlled moist heat. Goggles that hold the lids in a warm, humid chamber at a genuinely therapeutic temperature for a sustained period, followed by expression of the glands. This is what a facecloth is trying and failing to be. For blocked-but-intact glands, a properly heated and expressed lid does in twelve minutes what home compresses struggle to achieve in weeks.

IPL — intense pulsed light. Pulses of light applied to the skin around the eyes. The proposed mechanisms include reducing the abnormal blood vessels that carry inflammatory mediators to the lid margin, warming the glands, and an effect on Demodex. The evidence base in meibomian gland dysfunction — particularly where there's an underlying rosacea tendency — has grown considerably. Delivered as a course, typically three to four sessions a few weeks apart, not a single visit.

LLLT — low-level light therapy. Photobiomodulation, usually paired with IPL in the same appointment, applied over the lids to warm the glands and modulate inflammation. Comfortable and passive.

Tixel 2 — thermomechanical treatment. A titanium tip transfers precise heat to the skin around and on the lids in a fractional pattern. Used periorbitally in dry eye where the lid skin and gland function both need addressing.

Rexon-Eye — quantum molecular resonance. A high-frequency electric field delivered through a mask over closed eyes, aimed at the ocular surface and gland tissue itself. Given as a course of weekly sessions, and often the option considered where dryness is severe, longstanding, or hasn't responded to lid-directed treatment.

If you already know you want to explore light-based treatment, you can book that assessment directly:

Being straight with you about these

They are courses, not single appointments, and they represent a real investment of both time and money. We'll tell you what a full course involves before you start any of them.

They don't replace the home routine — they make it work. The lid hygiene and drops continue afterwards. People who stop their home care because they've "had the treatment" reliably end up back where they started.

Not everyone responds, and the response varies with mechanism and with how much gland structure remains. This is precisely why we measure first and why we re-measure after. If your meibography shows extensive dropout, we'll say so, and we'll be honest that the goal is protecting what's left rather than restoring what's gone.

And critically: a review date. Dry eye is a long-term condition and the plan is meant to be adjusted. Measuring once and never again tells you very little; measuring at intervals tells you whether you're winning.

The short version

  1. Start with the Complete Dry Eye Kit — heat at least 10 minutes once daily, lid spray once daily, lubricant three times daily, plus the targeted drop that matches your eyes, and the blink exercise every hour.
  2. Do all of it, daily, for two to three weeks. You should notice a difference in that window.
  3. Book the free Dry Eye Evaluation — whether it worked or not. If it worked, to protect the result. If it didn't, to find out why. It costs nothing, so there's no reason not to.
  4. Get a plan built on your numbers, and a date to re-measure.
