Meibography is a specialized imaging technique used by eye care professionals to visualize and evaluate the Meibomian glands, which are tiny, oil-producing glands located in the eyelids. This non-invasive procedure allows for a detailed assessment of their health and structure, which is important for maintaining a healthy tear film. 

During the imaging, the eyelid is gently everted or pulled slightly to expose the inner surface where the glands are located. The device then captures high-resolution digital images of both the eyelids. This imaging process is generally painless, with some patients reporting a slight pressure on the outer eyelid area. The captured images reveal the morphology, or structure and integrity, of the Meibomian glands.
