Why Are My Eyes Watery But Dry?

Your tears are made of multiple layers that work together to keep the eye surface smooth and comfortable. When the tear film breaks down too quickly, the surface of the eye can become irritated, and your body may respond by producing a flood of watery tears.

The problem is that these reflex tears are often more like an emergency rinse than a healthy tear film. They may run down your face or blur your vision, but they do not always fix the underlying dryness.

One of the most common reasons for watery-but-dry eyes is meibomian gland dysfunction, often called MGD. The meibomian glands are tiny oil glands in your eyelids. Their job is to add oil to your tears so the tears do not evaporate too quickly.

When these glands are clogged, inflamed, or not producing healthy oil, your tears may evaporate faster than normal. This can lead to burning, watering, blurry vision, and a gritty or sandy feeling. The TFOS DEWS II report describes evaporative dry eye driven by MGD as one of the most common forms of the disease.

Screen use often makes dry eye symptoms worse because people blink less often while using computers, phones, and tablets. Less blinking means the tear film is not spread across the eye as regularly, which can increase evaporation and irritation.

If your eyes water more during computer work, reading, or phone use, dry eye may be part of the problem.
