Watery eye is caused by excessive 'tearing'.
Tearing is a normal function of the eye and is produced from the tear
gland known as the 'lacrimal gland'. The moisture/ tears comprise oils,
water & antibodies which serve to protect the eye. However excessive
amounts may indicate underlying problems or ailments such as an eye
infections or allergic reaction.
Causes of watery eye
Tears are produced to help keep the cornea moist and healthy and are
spread across the eye by blinking. Watery eye, known medically as
epiphora, is excessive watering of the eye caused by a blockage of the
tear ducts or infection of the eye.
Other causes of watery eye include:
- Blepharitis – this is an inflammation of the eyelash follicles caused by bacteria found on the skin.
- Conjunctivitis – this is caused by a viral, bacterial or fungal infection of the conjunctiva (a clear membrane on the inside of the eyelid).
- Obstruction of the tear duct – the nasolacrimal duct can become blocked due to infection, polyps or weakened eyelid muscles.
- Irritation – anything that causes irritation of the eye such as allergies, grit or an ingrown eyelash can trigger watery eye.
- Lower eyelid droop
– this is known as ectropion and causes the lower eyelid to droop
forward preventing tears from being transported into the drainage
- Blocked canaliculus – a small channel in the corner of the eye (known as the canaliculi) can become blocked from inflammation or scarring.
