Persistent Dry Eyes: A Comprehensive Guide to Lasting Relief in Perth
Persistent dry eyes are more than just an occasional irritation at the end of a long day. They represent a chronic condition where your tear film fails to maintain its health and stability, leaving the delicate surface of your eye exposed, inflamed, and uncomfortable day after day.
For many residents in Wembley and the broader Perth area, this is not just a minor inconvenience; it is a daily struggle that affects productivity, mood, and overall quality of life. If your eyes regularly feel gritty, sore, or tired, or if they water constantly despite feeling dry, you are not alone.
Dry eye disease affects a significant portion of adults worldwide, and without the right management plan, symptoms tend to worsen over time, potentially leading to more severe ocular surface damage.
Here is a quick summary of what you need to know:
- Persistent dry eyes are caused by either insufficient tear production, poor tear quality, or rapid evaporation. In most chronic cases, it is a complex mix of all three factors.
- Common symptoms include stinging, burning, a gritty sensation, blurred vision, light sensitivity, and surprisingly, watery eyes that never seem to feel lubricated.
- Triggers include excessive screen time, air conditioning, hormonal changes, certain medications, and underlying health conditions like diabetes or autoimmune disorders.
- Over-the-counter drops can offer short-term relief, but a thorough eye test and dry eye assessment are the most important steps toward lasting comfort.
- A structured, personalised treatment plan – not just a generic solution – is what makes the difference for chronic cases, ensuring that the root cause is addressed rather than just the symptoms.
- Long-term eye health requires a holistic approach, including nutrition, environmental adjustments, and professional clinical management.

Understanding Persistent Dry Eyes and Why They Happen
To understand why persistent dry eyes occur, we first need to look at the remarkable system that keeps our eyes comfortable.
Every time we blink, a thin layer of liquid called the tear film is spread across the cornea (the clear front window of the eye). This film is not just “water”; it is a complex, three-layered structure designed to protect, nourish, and provide a smooth surface for clear vision. When this system breaks down, we develop what is medically known as dry eye disease.
According to the TFOS DEWS II definition and classification report, dry eye is a multifactorial disease of the ocular surface characterised by a loss of homeostasis (balance) of the tear film. This imbalance leads to instability, increased saltiness (hyperosmolarity), and inflammation, which can eventually damage the surface of the eye.
The difference between occasional and chronic dryness
Dry or irritated eyes can develop in everyday situations, such as extended time in air-conditioned environments or exposure to windy conditions. In these cases, the dryness is a temporary reaction to an environmental trigger. Once the trigger is removed or you use a simple lubricating drop, your eyes bounce back.
Persistent dry eyes are different. This is a chronic condition where the symptoms are present most days, regardless of the environment. It is often driven by an underlying issue with the glands that produce the tears or the way the eyelids function.
Over time, this chronic dryness leads to low-grade inflammation. This creates a “vicious cycle”: the dry surface causes inflammation, and the inflammation further damages the tear-producing glands, making the eyes even drier. Breaking this cycle requires more than just occasional drops; it requires a dedicated management strategy.
Why tear quality matters as much as quantity
Many patients are surprised to discover they can experience “dry eyes” even when their eyes feel watery or they seem to produce plenty of tears. The issue often isn’t the amount of tears, but their quality and stability.
Your tear film is made up of three essential layers that work together to keep the eye surface healthy:
- Lipid (oil) layer – slows evaporation
- Aqueous (water) layer – provides hydration
- Mucin (mucus) layer – helps tears spread evenly across the eye
When one of these layers is disrupted, the tear film becomes unstable. A common cause is Meibomian Gland Dysfunction (MGD), where the oil-producing glands in the eyelids become blocked or underperform.
Without a healthy oil layer, tears evaporate too quickly even if your eyes are producing enough fluid. This leaves the eye surface exposed, leading to irritation, dryness, and fluctuating vision.
To understand more about how these layers interact and what contributes to ongoing symptoms, you can explore our dry eye treatment on the service page.
Common Symptoms and How They Affect Your Day
The symptoms of persistent dry eyes are rarely just about feeling “dry.” In fact, the discomfort can manifest in several ways that interfere with your ability to work, drive, or enjoy your hobbies.
Patients often describe sore eyes that feel heavy or fatigued by mid-afternoon. This fatigue can lead to a decrease in concentration and a general sense of irritability, as the brain is constantly processing the discomfort coming from the ocular surface.
Identifying the gritty sensation of persistent dry eyes
A common symptom of persistent dry eye is a foreign body sensation like there’s grit or dust in your eye that won’t go away.
It often feels worse during focused tasks such as reading or computer work. Because the tear film is unstable, the eye surface becomes uneven, leading to fluctuating vision that may blur and clear throughout the day, often improving briefly after blinking.
Eye fatigue is also common. Contact lens wearers may notice increasing discomfort, with lenses feeling dry or like “sandpaper” by the end of the day. This can lead to reduced wear time or contact lens intolerance, especially for active individuals.
Why watery eyes are often a sign of dryness
Watery eyes are a key sign of dry eye disease. When the eye surface is irritated, the body produces reflex tears in response. These are mostly water and lack the oils and proteins needed for proper lubrication.
Because they are low quality, they don’t stay on the eye and quickly drain away, leaving the surface dry again. This creates a cycle of irritation and excessive tearing. More water isn’t the solution as the issue is tear quality, not quantity.
Common Triggers for Persistent Dry Eyes
There is rarely a single cause of chronic dry eye. In most cases, it develops from a mix of age, lifestyle, and environmental factors.
As we age, tear production naturally decreases, particularly after 50. Hormonal changes, especially during menopause, can also alter tear film quality and trigger new or worsening symptoms of sore, dry eyes.
Modern screen-heavy lifestyles are another major contributor. When focusing on screens, our blink rate can drop by up to 60%, from around 15 blinks per minute to as few as 5–7. This allows the tear film to break down more quickly, leading to dryness and irritation.
A simple habit that helps is the 20-20-20 rule: every 20 minutes, look at something 20 feet (about 6 metres) away for 20 seconds. This gives your eyes a chance to reset and maintain a healthier tear film.
Certain medications can also play a role. Research shows that hundreds of common medicines may reduce tear production as a side effect, contributing to ongoing dryness in some people.
Environmental factors in Western Australia
Living in Perth brings unique challenges for eye comfort. The climate is often hot, dry, and windy, especially during summer, which increases tear evaporation and contributes to dry eye symptoms.
Even the well-known Fremantle Doctor sea breeze, while refreshing, can accelerate moisture loss from the eye surface. Indoors, air conditioning is another common trigger, particularly in homes and offices across suburbs like Wembley. It reduces humidity, creating an environment that is harsh on the ocular surface. Indoor heating during cooler months can have a similar drying effect.
Environmental irritants such as dust and pollen in Western Australia may also contribute to low-grade inflammation, further destabilising the tear film. For those spending significant time outdoors, the high UV exposure in WA adds additional stress to the eye surface, making tear stability even harder to maintain.
How We Diagnose Your Condition in Wembley
At The Focal Point Optometrist in Wembley, dry eye diagnosis isn’t based on a quick check. Initial consultations run for a full hour, allowing a detailed investigation into symptoms and their underlying cause, not just surface discomfort.
The assessment begins with a comprehensive patient history, covering lifestyle, screen use, environment, diet, medications, and symptom patterns. This helps identify triggers and understand how the condition behaves over time.
Assessing Eyelid and Tear Film Health
A slit lamp microscope is used to examine the eyelids and tear film in detail.
The focus is on the meibomian glands, which produce the oily layer of tears that prevents evaporation. When these glands become blocked or the oil thickens, it can lead to Meibomian Gland Dysfunction (MGD), a leading cause of dry eye.
Signs of blepharitis are also assessed, including inflammation along the eyelid margins often linked to bacteria or Demodex mites. This can contribute to irritation, debris build-up, and tear film instability. This evaluation helps determine whether symptoms are driven mainly by tear evaporation or reduced tear quality.
Measuring Tear Production and Stability
A series of diagnostic tests can also be used to assess tear quality and quantity. The Tear Break-Up Time (TBUT) test measures how quickly the tear film begins to break after blinking. A stable tear film typically lasts around 10 seconds or more. A shorter duration suggests increased evaporation and tear film instability.
Fluorescein or lissamine green dyes may also be used to highlight dry areas on the eye’s surface and identify any damage.
To assess tear production, the Schirmer test is performed using a small strip of filter paper placed under the lower eyelid for five minutes. Reduced moisture levels may indicate insufficient tear production.
Blink patterns are also observed, as incomplete blinking can leave parts of the eye exposed, worsening dryness over time.
Practical Solutions and When to Seek Further Care
Managing persistent dry eyes starts with identifying the underlying cause and implementing targeted first-line strategies. For many patients, this includes regular use of preservative-free lubricating eye drops, environmental modifications, and improving eyelid hygiene.
Preservative-free artificial tears are generally preferred for frequent use, as certain preservatives such as benzalkonium chloride (BAK) have been associated with irritation and toxicity to the ocular surface when used long term.
In some cases, additional therapies such as prescription medications or in-clinic procedures may be recommended. Treatments like intense pulsed light (IPL) or low-level light therapy are increasingly used in specialised settings to manage meibomian gland dysfunction and inflammation.
While these advanced treatments are not required for every patient, individuals with persistent or severe symptoms may benefit from referral to a practitioner who offers these services.
At The Focal Point Optometrist, our role is to provide a thorough assessment, identify contributing factors, and guide you towards the most appropriate management pathway for your individual needs.
Nutrition and Home Care for Lasting Comfort
A holistic approach means looking at how your systemic health affects your eyes. Your eyes are part of a whole-body system, and what you eat and drink matters. Tear production requires adequate systemic hydration. We recommend drinking 8 to 10 glasses of water a day (approximately 2 to 2.5 litres).
In the Western Australian heat, it is very easy to become slightly dehydrated without realising it. When you are dehydrated, your body prioritises water for vital organs, often leaving your tear production as a secondary concern. Maintaining consistent hydration is one of the simplest yet most effective ways to support your ocular health.
Supporting your eyes from the inside out
Nutrition plays a vital role in tear quality. Scientific research on Omega-3 supplementation suggests that these essential fatty acids can improve meibomian gland function and reduce ocular surface inflammation. We encourage our patients to incorporate oily fish such as salmon, mackerel, or sardines into their diet at least 2-3 times a week.
For those who prefer plant sources, flaxseeds, chia seeds, and walnuts are excellent vegetarian options. Vitamin A is also essential for the health of the mucin (mucus) layer of the tear film and can be found in carrots, sweet potatoes, and leafy greens.
If you find it difficult to get enough of these through diet alone, talk to us about high-quality nutritional supplements. We also suggest consulting your General Practitioner (GP) if you feel your dryness is linked to systemic health issues, as they can manage any necessary oral scripts and ensure your overall health is optimised for eye comfort.

FAQs
Can persistent dry eyes cause permanent damage?
If left untreated, chronic dryness can lead to persistent inflammation, corneal abrasions, or even ulcers. These are essentially “sores” on the front of the eye that may cause permanent scarring and vision loss. Regular monitoring during an eye test is essential to catch these issues early and prevent permanent complications. Protecting the cornea is our primary concern in any dry eye management plan.
Why are my eyes dry even though they are watering all the time?
This is known as reflex tearing. When the eye surface becomes too dry or irritated, the brain sends an emergency signal to flood the eye with tears. However, these tears are mostly water and lack the essential oil needed to stay on the eye. As a result, they evaporate or run off the eye quickly, leaving the surface dry again almost immediately. It is a sign that your tear quality, rather than quantity, is the main issue.
How often should I use artificial tears?
For chronic cases of persistent dry eyes, we often recommend using preservative-free drops 4 times a day, even when your eyes feel fine. Think of it like using moisturiser on dry skin; it is much easier to maintain a healthy surface than it is to fix one that has already become inflamed and sore. Consistency is key to preventing flare-ups.
Is screen use the main cause of my dry eyes?
While screen use is a major trigger due to reduced blinking, it is rarely the sole cause. It usually exacerbates an underlying issue like Meibomian Gland Dysfunction or environmental dryness. Using the 20-20-20 rule and ensuring your workstation is ergonomically sound can help, but a professional assessment is needed to identify other contributing factors.
Can diet really improve my dry eye symptoms?
Yes, absolutely. The quality of the oil produced by your meibomian glands is directly influenced by your intake of essential fatty acids. Omega-3s help reduce inflammation and improve the consistency of the oil, making it easier for the glands to express it onto the eye surface. Combined with proper hydration, nutrition is a cornerstone of long-term dry eye management.
