Eye water, medically known as epiphora, refers to the condition of having watery eyes. Tears play a crucial role in lubricating and protecting the eyes. Epiphora arises when there is an overproduction of tears or when tears are not draining properly.
Causes of Watery Eyes (Epiphora)
Epiphora can be triggered by a variety of factors, including:
- Excess tear production: Allergies, infections, or irritants can stimulate increased tear production.
- Blocked tear ducts: Obstructions in the tear drainage system can prevent tears from draining properly, leading to watery eyes.
- Eye Irritation: Exposure to environmental factors like wind, dust, or smoke.
- Infections: Conjunctivitis (pink eye) and other eye infections.
- Allergies: Seasonal or environmental allergies.
Many causes of epiphora are benign and resolve without treatment. However, persistent or severe watery eyes should be evaluated by a healthcare professional.
Understanding Tear Function
| Function | Description |
|---|---|
| Lubrication | Tears keep the surface of the eye moist, preventing dryness and discomfort. |
| Protection | Tears wash away debris and foreign particles from the eye. |
| Antibacterial | Tears contain enzymes that help fight infection. |
| Clear Vision | Tears help create a smooth surface for light to enter the eye, aiding vision. |
In conclusion, "eye water" is a common term for the medical condition epiphora, which involves excessive tearing due to either overproduction or inadequate drainage of tears.
