If your eyes feel gritty, irritated or tired by the middle of the afternoon, you’re not alone. One of the most common issues we see in clinic nowadays is dry eye disease, which affects everyone from all walks of life and all ages. What was once a problem of the older population has got a new group of co-conspirators in recent times: our screens, our indoor environments, and, for many women, a change in life chapters.
However, most people don’t know that dry eyes aren’t as simple as not producing enough tears. And, surprisingly, for around 80 percent of people who have this problem, the cause has nothing to do with watery tears. At the edge of your eyelid there is a series of little glands called meibomian glands that secrete healthy oil, similar in consistency and appearance to olive oil, to prevent the tears from evaporating away too quickly.
But modern lifestyles are working against them. When we’re looking at screens, our normal blink rate can drop to as little as one tenth. That means less natural pressure on the glands, poorer oil flow and more rapid tear evaporation. It’s the perfect recipe for stinging, redness, blurry vision and that persistent “sand in the eye” sensation. Hormonal shifts, certain medications, air-conditioning, make-up use and even conditions like rosacea can all further inflame or block these glands.
Left unmanaged, the condition can progress. Using only lubricating drops often provides short-term relief but doesn’t address the root cause. In the last few years, with the help of advanced imaging, we’re seeing more patients whose glands have become permanently atrophied simply from years of untreated dysfunction.
That’s why early care matters. In our clinic, treatment often focuses on restoring natural gland function. In 2017, we pioneered the use of Intense Pulsed Light (IPL) for dry eye, a therapy which helps calm inflammation and abnormal blood vessels around the lids. More recently, we are the first Tauranga clinic to offer Lipiflow; a gentle thermal in-clinic procedure, that melts and clears thickened oils to 'reset' the glands. The best chance of long-term improvement for many people is to combine the two. Alongside this, recommendations include environmental tactics, targeted eye drops, lid hygiene and omega-3 supplements.
If you’re noticing dryness, irritation or fluctuating vision, a comprehensive assessment can identify the exact cause, and prevent years of discomfort.
Dry eye might be common, but living with it shouldn’t be.
