More patients are walking into clinic with the same complaint. Gritty, tired, burning eyes by mid afternoon.
It is not in your head, and it is not just getting older. Something has genuinely shifted, and here is what I see happening in practice, week after week.
What Dry Eye Actually Is
Your eye surface relies on three layers working together. Water, mucus and oil. Combined, they form the tear film.
When one of those layers is compromised, the whole system falls out of balance. Tears evaporate too fast, and the eyelid starts rubbing against the eye surface without enough lubrication.
It's not got any lubricant between the two surfaces. So the inner surface of the eyelid and the eyeball surface are literally just being sandpapered down.
Here is a number that puts it in perspective. Your eyelid travels roughly 300 metres in a single day, based on how often and how far you blink. That is the same height as the Eureka Skydeck, Melbourne's tallest building. Every day, your eyelid covers that distance. Without lubricant, it does it with friction the whole way.
Why It Is Genuinely Getting Worse
This is not a perception problem. A 2003 Blue Mountains Eye Study found at least one dry eye symptom in 57.5 percent of Australians over 50. That figure predates the smartphone entirely. Given how much screen exposure has changed since then, current prevalence is widely considered to be significantly underestimated.
There are a few specific reasons Australians are seeing this rise now, and they compound on each other.
1. Reduced Blinking on Screens
Most people blink once every 20 seconds on a screen. That is the biggest thing. People do not realise that.
A normal blink rate is once every 3 to 4 seconds. On a screen, that drops to once every 20 seconds. Less blinking means your meibomian glands, the tiny oil glands along your eyelid margin, are not being expressed properly, and less oil reaches the tear film.
2. The Australian Climate and Indoor Environment
Heat and evaporation are the primary drivers of dry eye through an Australian summer. Add central Australian dust carried on the wind, and it lands directly on the eye surface, collected by the eyelashes.
Air conditioning compounds the problem. It pulls moisture out of the air indoors, and out of your eyes along with it. Contact lens wearers face an added risk, since silicon hydrogel lenses behave like a sponge, drawing water away from the eye surface.
3. Diet
Diet plays a bigger role here than most people expect. I went through a stretch of about a year where fast food was my regular lunch.
I did that for a year, so I know categorically for me, fast food led to dry eyes.
High fat, processed meals affect the same oil glands responsible for keeping the tear film stable. Patients with better sugar, cholesterol and lipid control consistently report fewer eye surface complaints.
4. Hay Fever Season
Australian autumn brings a large jump in presentations of itchy, red, irritated eyes. Hay fever triggers histamine and cytokine release, which inflames an eye surface that is often already dry, intensifying both the itching and the friction discussed earlier.
What the Research Confirms
The TFOS DEWS II Epidemiology Report, one of the most comprehensive global reviews of dry eye disease, found prevalence ranging from 5 to 50 percent depending on how it is measured, with women consistently showing higher rates than men.
On the screen specific connection, a 2021 review published in Clinical Ophthalmology examined digital screen use and dry eye disease directly. It found that screen use reduces both blink rate and blink completeness, allowing greater evaporative loss from the tear film over time.
Warm compress therapy carries its own solid evidence base. A 2024 evidence review in Ophthalmology and Therapy examined two decades of clinical studies on warm compress protocols for meibomian gland dysfunction, and found consistent improvement in gland function and tear quality, including with simple self heating eye masks.
And on natural options, a 2023 meta-analysis in Clinical and Experimental Optometry reviewed five randomised controlled trials involving 288 adults with dry eye. It found manuka honey based treatments led to significant improvement in symptom scores and tear film quality compared to control groups.
What Most People Get Wrong
Most patients believe eye drops will fix dry eye completely. They will not.
Drops support the repair of the eye surface. They do not resolve why the surface is drying out in the first place. That underlying cause is almost always your daily environment, screen habits, blink rate, air conditioning, diet, and meibomian gland health, all working together.
What Actually Helps
The approach that works is layered, matched to how blocked your glands already are.
Level 1, mild and early. Change your blink rate consciously, drink more water, take regular screen breaks, and gently massage the eyelids.
Level 2, moderate. Add a hot compress, lubricating drops to repair the eye surface, and an oil based lipid spray or gel you can carry through the day.
Level 3, significantly blocked. This is where clinical treatment, such as low level light therapy, becomes appropriate to melt and clear blocked meibum before it can be expressed manually.
For most people managing this at home, a few products make a real difference. Preservative-free eye drops are the safer daily choice if you are using drops regularly rather than occasionally, since preservatives can build up in the eye over time and trigger their own inflammatory reactions. A warm compress paired with manuka honey drops addresses both the gland blockage and the surface hydration together, rather than treating them as separate problems.
If your glands are the main concern rather than surface hydration, the standalone Meibomian Gland Dry Eye Kit focuses purely on that morning routine. And through the drier winter months specifically, a leaner option like the Dry Eye Relief Bundle pairs a warm compress with an overnight gel and daytime drop.
Anyone with dry eyes, that 3D sleep eye mask that we have on Eyehouse is an absolute go to. I would 100 percent recommend that.
Diet also plays a supporting role. Many patients notice meaningful improvement after two to three months of consistent omega-3 supplementation, since it supports the oil layer that keeps your tears from evaporating too quickly.
A Note on Meibomian Gland Dysfunction
Meibomian gland dysfunction is the leading cause of dry eye, and it develops slowly, often without obvious symptoms at first.
Over time, if you do not look after those meibomian glands, they die, so they simply disappear. And once they are gone, they are gone. Research is pointing towards - you cannot get them back.
This is why early, consistent care matters more than reaching for a drop only when things feel bad. Daily eyelid hygiene supports the same goal, keeping the gland openings clear before blockage becomes permanent.
Who Is Most at Risk in Australia
This affects anyone who spends long hours on a screen, whether that is a full workday at a desk or a household juggling devices, work and family.
It is especially relevant if you are in your 40s, 50s or entering perimenopause, when hormonal changes commonly reduce natural tear production. Contact lens wearers, outdoor workers exposed to wind and UV, and anyone in an air conditioned office are all at higher risk.
If screens are the biggest factor for you specifically, pairing eye care with a screen protector tackles both sides of the problem. Less strain during the day, and less demand on an already reduced tear film.
Quick Answers
Why are dry eyes becoming more common in Australia?
A combination of increased screen time, which reduces blink rate, along with Australia's heat, dust, and widespread indoor air conditioning, all of which accelerate tear evaporation.
Is dry eye a serious condition?
For most people it is manageable rather than dangerous, but left unaddressed it can progressively damage the meibomian glands, which do not regenerate once lost.
Can dry eye be treated naturally?
Yes, to a meaningful extent. Manuka honey based drops have research support for improving symptoms, alongside habits like proper hydration, regular blinking breaks, and warm compress use.
Does screen use actually cause dry eye?
Screen use itself does not damage the eye directly, but it dramatically reduces how often you blink, from roughly once every 3 to 4 seconds to once every 20 seconds, and that reduced blinking is strongly associated with dry eye symptoms.
How long does it take for treatment to start working?
Most people notice initial improvement within a few weeks of consistent habits. Meibomian gland recovery and deeper tear film stability can take longer, often two to three months.
Why do my eyes still feel dry even though I use eye drops?
Drops support the eye surface but do not address the underlying cause, most often blocked meibomian glands or an unmanaged screen and environment routine.
FAQs
Is dry eye more common in women?
Yes. Research consistently shows higher prevalence in women, partly linked to hormonal changes affecting tear production, particularly around perimenopause and menopause.
Can air conditioning really cause dry eye?
Yes. Even with normal meibomian gland function and adequate hydration, air conditioning alone reduces tear film stability by stripping moisture from the air around your eyes.
Should I stop wearing contact lenses if I have dry eye?
Not necessarily, but it is worth reviewing lens type, wear schedule, and solution with your optometrist, since some lens materials place more demand on the tear film than others.
What is the difference between allergy related redness and dry eye?
Allergy related redness typically comes with itching and is seasonal. Dry eye tends to feel gritty rather than itchy and is often worse later in the day after screen use. The two frequently occur together.
When should I see an optometrist rather than managing this myself?
If symptoms persist despite basic changes to blink rate, hydration, and drop use, or if you notice pain, light sensitivity, or vision changes, book an assessment rather than continuing to self manage.
The Bigger Picture
Dry eye rarely announces itself all at once. It builds slowly, through years of screen habits, air conditioning, and glands that quietly stop working the way they should.
The good news is that prevention and protection now make a real difference later. You do not need to wait until symptoms are severe to start building better habits.
That is the whole idea behind Prevent, Protect, Preserve. Small, consistent actions today protect the comfort and clarity of your eyes for decades to come.
