Dry Eye Disease: Causes, Treatments and What Actually Works

DTDr Zobaida Tahiri·March 2025·7 min read

Dry eye disease is one of the most common conditions we see at Prime Optometrists Auburn, and one of the most frequently underestimated. People assume it's a minor nuisance, something a few drops from the chemist will fix. But for the roughly 1 in 5 Australians affected, dry eye is a chronic condition that, without proper diagnosis and treatment, tends to worsen over time rather than resolve on its own.

The Symptoms Nobody Expects

Dry eye presents in ways that surprise many patients. Beyond the classic gritty, burning sensation, it can also cause:

  • Blurred vision that fluctuates, especially late in the day or during screen use
  • Light sensitivity (photophobia)
  • Discomfort or intolerance when wearing contact lenses
  • Eye fatigue after reading or screen work
  • Watery eyes, yes, really

Why Are My Eyes Watery If I Have Dry Eye?

This is the question we hear most often. When the eye's surface is chronically irritated, the lacrimal gland responds by producing a sudden flood of reflex tears, watery, poor-quality tears that don't address the underlying problem. The eye is, in effect, overreacting to dryness. Watery, runny eyes, especially in cold weather or wind, can absolutely be a sign of dry eye disease.

The Two Types of Dry Eye

Aqueous Deficient Dry Eye

The lacrimal glands simply don't produce enough tear volume. Less common, more often associated with autoimmune conditions like Sjögren's syndrome, certain medications, or age-related changes.

Evaporative Dry Eye and MGD

By far the more common type, tears evaporate too quickly because the oily outer layer of the tear film is insufficient. This oil is produced by the meibomian glands along the eyelid margins. When these glands become blocked, their secretions thicken and solidify, reducing oil flow onto the tear film. This is Meibomian Gland Dysfunction (MGD), the most common underlying cause of chronic dry eye.

Here's the problem with generic eye drops in MGD: standard lubricating drops add watery volume but don't replace the missing oil layer. Without that oil layer, tears continue to evaporate rapidly regardless of how many drops you use. This is why many patients find drops give temporary relief but never truly solve the problem.

What Causes Dry Eye?

  • Screen use: Blink rate drops by up to 60% when concentrating on screens, increasing evaporation
  • Ageing: Both tear production and meibomian gland function decline naturally
  • Hormonal changes: Significantly more prevalent in post-menopausal women
  • Medications: Antihistamines, antidepressants, and some blood pressure medications all contribute
  • Contact lens wear: Disrupts the tear film and increases evaporative loss
  • Air conditioning and heating: Low-humidity indoor environments increase tear evaporation significantly
  • Previous LASIK surgery: Disrupts corneal nerves, reducing blink reflex and lacrimal gland function

What Actually Works (And What Doesn't)

At-Home Management

  • Preservative-free lubricating drops: Drops containing preservatives can worsen the ocular surface with frequent use. Preservative-free formulations are preferable for daily use. The right viscosity depends on your dry eye type, we guide patients toward appropriate products based on their clinical profile.
  • Warm compress and lid massage: For MGD specifically, 5–10 minutes of warm compress daily softens solidified secretions. Following with gentle lid massage encourages oil flow. One of the most evidence-backed at-home interventions, but only works if done consistently and at the right temperature (at least 40°C).
  • Omega-3 supplementation: High-quality fish oil or flaxseed supplements have clinical evidence supporting improved meibomian gland function and reduced dry eye symptoms over 3–6 months of consistent use.
  • Blink exercises during screen use: Making a conscious effort to blink fully and regularly during screen tasks reduces evaporative tear loss, combine with the 20-20-20 rule.

In-Clinic Treatment

  • Meibomian gland expression: Professional in-clinic expression of blocked glands removes hardened secretions that at-home warm compresses cannot clear. This can produce immediate, significant improvement in gland function and forms the cornerstone of in-clinic MGD management.
  • Prescription anti-inflammatory drops: In moderate to severe dry eye, chronic inflammation perpetuates the cycle of dysfunction. As a therapeutically endorsed optometrist, Dr Tahiri can prescribe cyclosporin A (Restasis/Ikervis), which reduces inflammation and restores ocular surface health in ways lubricating drops cannot.
  • IPL therapy (Intense Pulsed Light): An in-clinic treatment with strong emerging evidence for MGD and evaporative dry eye. Light energy targets abnormal blood vessels around the eyelid margins, and the heat effect improves meibomian gland function. Results build across a series of sessions.

“The mistake most people make is just managing symptoms with whatever drops are on special at the chemist. Dry eye has a cause, and if you treat the cause, particularly with MGD, the symptoms genuinely resolve rather than just being temporarily suppressed.”
, Dr Zobaida Tahiri, Optometrist Auburn

When Should You See an Optometrist?

Book a proper dry eye assessment rather than continuing to self-manage if:

  • You've been using eye drops daily for more than a few weeks without sustained relief
  • Your symptoms are affecting work, screen use, or contact lens tolerance
  • Your vision fluctuates, blurring and then clearing, through the day
  • Your eyes are consistently red or irritated
  • You have watery eyes that your GP hasn't been able to explain

The initial eye examination is bulk billed under Medicare. Our dry eye assessment involves a comprehensive evaluation of your tear film, meibomian gland health using diagnostic imaging, and ocular surface, giving us the information to build a genuinely targeted treatment plan.
