Watering eyes are common and often get better on their own, but treatment may be needed if the watering affects your daily activities.
It's normal for your eyes to water in smoky environments or if you're outside in the cold or wind.
An eye injury or something in your eye, such as an eyelash or a piece of grit, can also make your eyes water.
Sometimes watering eyes can be caused by a condition such as:
Babies often have watering eyes because their tear ducts are small. It usually gets better by the time they're 1 year old.
If your GP cannot find what's causing your eyes to water, they may refer you to an eye specialist (ophthalmologist) for tests.
Treatment may not be needed if the watering is not causing problems.
If treatment is needed, it will depend on what the cause is.
