Unique Tear Factory

The lacrimal gland is responsible for producing the watery component of tears, which helps keep the eyes moist and lubricated. Without this gland, our eyes would be prone to dryness and discomfort.

Nature’s Protective Shield

Tears produced by the lacrimal gland contain special proteins and enzymes that help protect the eyes from infections and irritants. They form a natural shield that keeps the eyes clean and healthy.

Emotional Tears

The lacrimal gland is responsible for producing tears in response to emotions such as sadness, joy, or laughter. These emotional tears have a different composition than basal tears, reflecting the impact of our feelings on our physiology.

Two Types of Tears

The lacrimal gland produces both basal tears, which keep the eyes moist and lubricated throughout the day, and reflex tears, which are triggered by irritants like onions or debris in the eye.

Size and Shape

The lacrimal gland is small, measuring around 10 mm in length and 6 mm in width. It has an almond-like shape, fitting neatly in the bony cavity of the eye socket.

Nourished by Blood

The lacrimal gland receives its blood supply from the ophthalmic artery, ensuring the delivery of oxygen and nutrients necessary for its proper functioning.


The lacrimal gland is innervated by the lacrimal nerve, a branch of the ophthalmic nerve. This nerve carries sensory information and controls tear production.

Lacrimal Gland Dysfunction

Dysfunction of the lacrimal gland can lead to conditions such as dry eye syndrome, where inadequate tear production causes discomfort, dryness, and blurred vision.

Regeneration Ability

The lacrimal gland has the remarkable ability to regenerate and repair itself. This allows it to maintain its function even after minor injuries or surgeries.

Gender Differences

Studies have shown that the size and activity of the lacrimal gland can vary between males and females. Women generally have a higher tear production rate, which may contribute to their higher risk of experiencing dry eye.

Aging and Lacrimal Gland

As we age, the lacrimal gland may undergo changes that can affect tear production, leading to dry eye symptoms. This highlights the importance of proper eye care, especially in older adults.

Lacrimal Gland Disorders

Various disorders can affect the lacrimal gland, including lacrimal gland tumors, infections, and autoimmune conditions. Regular eye examinations play a vital role in early detection and management of such disorders.

These 12 astounding facts about the lacrimal gland emphasize its crucial role in maintaining eye health and the importance of tear production. The next time you shed a tear, remember the intricate workings of this small but mighty gland!


The lacrimal gland is a remarkable and often overlooked part of the human anatomy. It plays a crucial role in producing tears and keeping our eyes moist and healthy. Understanding the lacrimal gland can provide insight into various eye-related conditions and enhance our overall understanding of the human body.

From its location near the upper outer corner of the eye to its intricate structure and function, the lacrimal gland offers fascinating insights into the workings of our visual system. Whether it’s protecting our eyes from irritants or helping to express emotions through tears, the lacrimal gland plays an essential role in maintaining our eye health.

Exploring the remarkable facts about the lacrimal gland can help us appreciate its importance and encourage further research in this field. By gaining a deeper understanding of the lacrimal gland, we can continue to advance in the diagnosis and treatment of eye-related conditions.


1. What is the lacrimal gland?

The lacrimal gland is a small almond-shaped gland located near the upper, outer corner of the eye. It produces tears and helps to keep the eyes lubricated.

2. How does the lacrimal gland produce tears?

The lacrimal gland produces tears by secreting a watery fluid composed of water, proteins, electrolytes, and antibodies. These tears then flow over the surface of the eye, providing moisture and protection.

3. What is the role of tears produced by the lacrimal gland?

Tears produced by the lacrimal gland serve several important functions. They help keep the eyes lubricated, wash away debris and irritants, and contain enzymes and antibodies that help fight against infection.

4. Can issues with the lacrimal gland cause eye-related problems?

Yes, issues with the lacrimal gland can lead to various eye-related problems. Conditions such as dry eye syndrome, excessive tearing, or glandular tumors can arise due to lacrimal gland dysfunction.
