Watering eyes occur if too many tears are produced or they can’t drain away properly.
The problem can affect anyone, but it’s most common in young babies and people over 60.
Glands in the eyelids (Meibomian glands) normally secrete an oily substance that slows the evaporation of tears between blinks.
When these glands don’t function properly, known as Meibomian gland dysfunction (MGD), it can result in dry patches on your eyes.
These become sore and extra tears are produced as a reflex. This is the most likely cause of watering eyes.
It can cause blurred vision, sore eyelids and sticky eyes.
