About Dry Eye
Dry eye is not just "eyes that need a drop."
It's a chronic, measurable condition of the tear system — and once you understand what's actually going on, it stops feeling like something you just have to live with.
This page is a plain-English guide to what dry eye disease actually is, why it's so often missed, and what a proper assessment looks like.
By the numbers
What "dry eye" actually means
A healthy tear film is a thin, three-layer coating — water, oil and mucin — rebuilt every time you blink. It keeps the surface of your eye smooth, comfortable and clear.
Dry eye disease is what happens when that system breaks down. The clinical definition, from the Tear Film & Ocular Surface Society, calls it a "multifactorial disease of the ocular surface characterised by loss of tear film stability, ocular surface inflammation and damage, and neurosensory abnormalities."
In plain English: not enough tears, or the wrong kind of tears, plus low-grade inflammation that stops the surface healing itself. It's usually a mix. And it needs a plan built for your mix — not a bottle picked off the shelf.
Why symptoms and signs disagree
One of the most striking findings in modern dry eye research: symptoms and clinical signs often don't match up. Some people whose eyes look fine at a standard eye test have significant discomfort. Others with visible surface damage report only mild symptoms — because chronic inflammation quietly dulls the corneal nerves that would normally tell you something's wrong.
That's why we don't rely on "how do your eyes feel?" alone. A proper assessment measures both — with structured symptom questionnaires (SPEED, OSDI) and objective tests (tear film stability, meibography of the oil glands, staining patterns, tear osmolarity).
The 6.5-year problem
On average, people put up with dry eye symptoms for six and a half years before they get a proper assessment. That's usually because they've been told "everyone gets a bit of dry eye," or handed another bottle of drops, or told their symptoms are just age or screen use.
The problem with waiting: dry eye is a progressive condition. Meibomian glands that stay blocked for years start to shrink and drop out — and while most of that damage is reversible, some of it isn't. Catching it earlier means faster, more complete results and a smaller ongoing routine.
The chronic-inflammation link also matters for the rest of the body. Dry eye significantly increases the odds of low mood, poor sleep, and reduced quality of life at work and driving — because your eyes are uncomfortable more or less all day.
What a proper assessment looks like
A dry eye assessment isn't a ten-minute chat and a leaflet. Ours takes about 45 minutes and includes:
- • A structured symptom questionnaire (SPEED and/or OSDI) so we can measure change over time.
- • Tear film analysis — how quickly the film breaks up, how much volume you have, and whether the tears are too concentrated.
- • Meibography — imaging of the oil glands in your eyelids to see if any have been lost or blocked.
- • Slit-lamp examination with dyes to look for surface damage on the cornea and conjunctiva.
- • Lid margin and blink assessment — because incomplete blinking makes everything worse.
- • A medical review — medications, thyroid, hormones, autoimmune status, and any conditions that might be driving the picture.
You leave with a written plan built around what's actually happening on your ocular surface — not a generic protocol.
Who is it for?
Dry eye is more common — and more consequential — in a few specific groups. If any of these apply to you, an assessment is well worth doing:
