Krause's glands are small accessory lacrimal glands located deep in the conjunctival fornices. They secrete a steady flow of aqueous fluid that mixes with other tear components. This baseline output keeps the ocular surface hydrated between blinks. The glands help maintain comfort and clarity during daily activities.

The glands of Krause are small, lobular structures located in the conjunctival fornices. They resemble the main lacrimal gland in histology, with acini lined by serous cells. Each gland connects to ducts that open onto the ocular surface. Their steady secretion supplements the aqueous layer of the tear film.
Krause's glands add to the tear film by producing small amounts of tears that keep the eye hydrated. Their contribution supports lubrication and protects against dryness and irritation.
Understanding the anatomy of the eye helps explain how vision works and why each part is important for healthy sight. From the cornea that focuses light to the retina that captures images, every structure plays a precise role. Learning about these components encourages better eye care and awareness of changes that could signal a problem.
They supply basal aqueous volume that mixes with mucus and oil. The blend forms a cohesive film that resists evaporation and friction. Consistent secretion helps stabilize the optical surface. This support makes vision feel smooth and steady.
The main lacrimal gland provides reflex tearing during emotion or irritation. Krause's glands are smaller and dispersed, providing routine background moisture. Both sources interact to keep the surface balanced. Their partnership sustains day long comfort.
Continuous fluid from these glands keeps the cornea slick for blinking and movement. A stable film reduces light scatter and supports sharp images. Even in dry environments, their baseline output helps. These quiet glands support comfortable sight.
Are they visible? No, they are embedded in eyelid tissues.
Do they exist in both lids? Yes, accessory glands are present in upper and lower fornices.
Can they stop working? Output can decline with age, affecting surface comfort.
