Do your eyes feel dry, tired or irritated in offices, shopping centres or airplanes?
Air-conditioned environments reduce humidity. This increases tear evaporation from the surface of the eye.
▫️ When the tear film becomes unstable, symptoms may include:
* Dryness or grittiness
* Burning sensation
* Blurred vision that improves after blinking
* Eye fatigue
Screen use can worsen the problem.
Blink rate decreases during digital device use, which further disrupts the tear film.
Dry eye symptoms are common in indoor environments and are usually related to tear instability rather than infection.
▫️ Simple measures may help:
* Blink fully and consciously during screen use
* Follow the 20-20-20 rule
* Position screens slightly below eye level
* Stay hydrated
* Consider preservative-free lubricating eye drops if needed
Persistent discomfort, redness or fluctuating vision should be evaluated to rule out underlying dry eye disease.
Small environmental adjustments can make a meaningful difference in daily visual comfort.
