Understanding the Connection Between Blepharitis and Dry Eye Syndrome  

Why These Conditions Often Go Hand in Hand  

Red, itchy, irritated eyes and inflamed eyelids are more than just a minor nuisance—they may signal the presence of blepharitis, a chronic inflammation of the eyelid margins. While blepharitis is not always synonymous with dry eye disease, the two conditions often appear together. Eyelid inflammation can contribute to dry eye, although the underlying causes vary between patients.

Both the skin and the eyelids naturally harbour bacteria. This is normal and usually harmless. However, when there is an overgrowth of bacteria at the base of the eyelashes, the toxins they produce can inflame the meibomian glands—tiny oil-producing structures in the eyelids that play a crucial role in tear quality. When these glands become blocked or dysfunctional, the result is often unstable tear film and the uncomfortable dryness that patients know all too well.

“Blepharitis and dry eye are closely intertwined,” explains Gary Rodney, founder and creator of Smart Vision Optometry, Master of Optometry, Behavioural Optometrist and Fellow of the International Academy of Orthokeratology and Myopia Control (FIAOMC). “The eyelids are central to tear production. If they’re inflamed, the tears lose their protective balance, and the cycle of irritation continues.”

A Common Yet Under-Recognised Condition  

Blepharitis can be overlooked, leaving people unaware that red, gritty eyes may need assessment rather than being attributed to fatigue or allergies. The previously stated Australian lifetime-prevalence estimate has been removed because a specific supporting study was not identified.

Blepharitis is typically long-lasting, and while treatment can significantly reduce symptoms, it often requires ongoing management rather than a one-time cure.

“One of the challenges is that blepharitis doesn’t just disappear on its own,” says Jacquie Gattegno, Orthokeratologist and Principal Optometrist at Eyes InDesign Smart Vision Optometry Bondi. “People sometimes ignore the irritation until it becomes severe. But the earlier it is managed, the better the outcome for long-term eye comfort and health.”

Advanced Treatments Offering Relief  

Traditionally, treatment for blepharitis relied on eyelid hygiene—clinician-advised warm compresses, suitable eyelid cleansers, and topical treatments. While helpful, these methods are not always enough. Practitioners may also discuss in-office procedures when appropriate.

In-office treatments may be considered after assessment. Their suitability, risks and likely benefit vary. Options discussed in this interview include:

• BlephEx®: An in-practice eyelid-cleaning procedure intended to remove debris from the lid margins.
• BlephaSteam®: A heat-based treatment intended to help soften thickened oil-gland secretions.
• Smart IPL Dry Eye Treatment: Intense pulsed light may be discussed for selected patients with meibomian gland dysfunction. Ask the Mosman practice about availability, suitability, risks, alternatives and the review plan; lasting relief is not guaranteed.

“Patients often tell us the difference is life-changing,” Rodney says. “These technologies mean we can break the cycle of redness, itchiness, and irritation much more effectively than before.”

Lifestyle Choices That Make a Difference  

Alongside professional advice, daily habits may affect eye comfort. Individual triggers and responses vary.

Adopting healthy routines can make symptoms more manageable:

• Nutrition: A balanced diet supports general health. Omega-3 supplements are not an established substitute for dry-eye assessment or treatment.
• Makeup hygiene: Women should avoid eye makeup during active flare-ups. When using cosmetics, choose products designed for sensitive skin and replace applicators regularly.
• Screen habits: Following the “20-20-20 rule” (every 20 minutes, look 20 feet i.e. 6 metres away for 20 seconds) reduces digital eye strain, which can aggravate dry eye symptoms.
• Consistency: Regular eyelid hygiene routines—such as warm compresses or gentle lid scrubs—help prevent bacteria and oil build-up.

“Lifestyle factors don’t cause blepharitis on their own, but they can definitely make it worse,” Gattegno explains. “By being mindful about diet, makeup, and daily screen use, patients can reduce the frequency and intensity of flare-ups.”

Why Early Care Matters  

Left untreated, blepharitis can progress into more serious problems, including chronic dry eye disease, recurrent styes, and even damage to the cornea. Because symptoms can mimic allergies or fatigue, people often delay seeking care—only to find themselves dealing with persistent discomfort later on.

“Ignoring blepharitis is never the answer,” Rodney emphasises. “The sooner it is addressed, the less likely it is to interfere with daily life, productivity, and overall wellbeing.”
