the thin layer of tear fluid coating the front surface of the cornea; composed of three layers: lipid layer (most anterior), lacrimal layer (middle), and mucoid layer (most posterior)
Lacrimal film; the layer of lubricating substances that coats the sclera and conjunctiva, nourishes and protects the cornea, and lubricates the eye.
Layered film on the surface of the cornea that keeps the eye lubricated.
The thin layer of lubricants and nutrients that covers the front surface of the cornea
A layer of fluid that bathes and lubricates the cornea.
the clear saline fluid covering the front surface of the eye and secreted by the lacrimal and accessory glands.
The clear saline fluid which cleanses and lubricates the front surface of the eye
A very thin film of water and other chemicals riding on top of the epithelium that lubricates the front of the eye.
The liquid layer bathing the cornea and conjunctiva. It creates a perfectly smooth liquid outer layer that polishes the corneal surface, mechanically traps and flushes out foreign bodies and chemicals, contains bacteriostatic substances that inhibit the growth of microorganisms, and reduces the surface friction associated with eyelid blinking and eye movement.
