What it actually feels like is burning. Grittiness, as though there is sand in the eye. Heaviness and redness that get worse through the day. Blurring that clears for a second when you blink hard. And very often — watering. Many people are surprised to be told their constantly watering eyes are a dry eye problem. The watering is a reflex: the eye surface is irritated, so it floods with tears that drain away immediately without ever coating the eye properly.
Delhi makes all of this worse. Air pollution, dust, air-conditioned offices and long screen hours all break down the tear film. When you stare at a screen, your blink rate drops by more than half — and you never notice it happening.
Here is the part that matters most: dry eye is not one condition. Some people don't produce enough tears. But far more people produce plenty of tears and lose them too quickly, because the tiny oil glands in the eyelids (the meibomian glands) are blocked. These two problems need completely different treatment. It is the reason ordinary lubricating drops help some people and do nothing for others.
