Anatomy and Location of Meibomian Glands Unlike the water-producing lacrimal glands, the oil glands in eyes are specialized sebaceous glands located within the eyelids themselves. These oil glands in eyes , formally known as the meibomian glands, represent a critical component of the tear film that prevents rapid evaporation of the eye's protective moisture.

Consequently, the eyes may feel gritty, burning, or excessively watery as the body attempts to compensate for the instability. When these structures function optimally, they remain unnoticed, but when dysfunction occurs, the resulting discomfort can significantly impact daily life.
These glands are structurally similar to oil-producing glands found elsewhere in the body, but their specific role is to secrete a lipid-based substance directly onto the tear film surface. There are approximately 25 to 40 glands in the upper eyelid and 20 to 30 in the lower, arranged in a single row parallel to the lash line.

The mucin layer adheres tears to the corneal surface, the aqueous layer provides moisture and nutrients, and the outermost lipid layer is where the meibomian secretions take effect. Impact on Eye Health Chronic dysfunction of the oil glands in eyes can lead to more than just temporary discomfort.
