Eye rubbing isn’t harmless — it’s repetitive trauma to the cornea

Every rub puts mechanical stress on the corneal surface, and over time this can change its shape

What that can lead to: • Astigmatism (irregular curvature → blurred/distorted vision)
• Keratoconus (progressive thinning + bulging of the cornea)

Why it matters: The cornea is designed to be smooth and stable — repeated rubbing weakens its structure and can accelerate these changes, especially in patients with allergies or underlying susceptibility

High-risk group: • Chronic eye rubbers
• Allergy sufferers (itchy eyes)
• Younger patients (more elastic corneas)

Better alternatives: • Treat the itch (antihistamine/mast cell stabiliser drops)
• Cold compress instead of rubbing
• Lubricating drops

If you’re rubbing your eyes often, there’s usually an underlying reason — and it’s worth addressing early

Air con, heating & your environment 👇

A major trigger for Dry Eye Disease

Air conditioning, heaters, wind, dry climates and chemicals all affect the tear film layer.

This leads to:
Faster tear evaporation
Increased irritation → reflex tearing
Burning, redness, fluctuating vision

Common culprits:
Air con blowing directly on your face
Car vents
Office environments
Perfumes
Cleaning chemicals

Why it matters:
Your tears don’t last as long → unstable tear film

What helps:
Avoid direct airflow to the eyes
Use a humidifier where possible
Stay hydrated
Consider targeted lubricating drops
Avoid chemicals and irritants

Your environment plays a bigger role in dry eye than most people think.

Screen time & dry eyes 👇

Using screens is a major driver of Dry Eye Disease

When you’re on your phone, computer, or iPad:
Blink rate drops (up to 60%)
Blinks become incomplete
Tears evaporate faster

This leads to:
Burning, irritation, fluctuating vision
Watery eyes (reflex tearing)
End-of-day eye fatigue

Why?
Less blinking = less oil spread from your lids → unstable tear film

Simple tips:
Consciously blink fully
Take regular breaks
Optimise your setup (screen slightly below eye level)

Watery eyes from dry eye? Here’s the real reason 👇

In Dry Eye Disease:

Irritation → nerve stimulation → reflex tearing

When the eye surface dries out, the corneal nerves fire a distress signal.
That signal travels to the lacrimal gland, triggering a surge of watery tears to protect the eye.

But these are reflex tears—they’re fast and watery, not well-balanced—so they don’t stay on the eye long enough to fix the problem.

Result:
💧 Watering + ongoing irritation

Your eyes aren’t overproducing tears—they’re overreacting to irritation.
