The lacrimal gland is a small, almond-shaped gland located in the upper, outer part of each eye socket. It produces tears, which are essential for maintaining the health and function of the eye. Tears are a complex mixture of water, oils, and other substances that help to lubricate, nourish, and protect the surface of the eye.
The lacrimal gland is connected to the eye by a small duct (tube) called the lacrimal duct. When you blink, the lacrimal gland releases a small number of tears onto the surface of the eye. These tears then spread over the eye and drain into the lacrimal duct, which carries them to the nasal cavity.
Tears are produced continuously, but their production increases in response to certain stimuli, such as when the eyes are dry or when you are feeling emotional. Dry eyes, or a deficiency in tears, can lead to discomfort and irritation and can be treated with artificial tears or other medications.« Back to Glossary Index
