How many layers does the cornea of the eye have?

The cornea of the eye is composed of six distinct layers, which work together to facilitate light transmission and contribute to the eye's overall function.

The layers of the cornea include the following:

1. Epithelium - This is the outermost layer, serving as a protective barrier against dust, debris, and microorganisms.

2. Bowman's Layer - This thin layer lies beneath the epithelium and provides structural support.

3. Stroma - The thickest layer, the stroma is made up of collagen fibers that maintain the cornea's shape and transparency.

4. Descemet's Membrane - This thin layer separates the stroma from the endothelium and provides additional structural support.

5. Endothelium - The innermost layer, which regulates fluid and maintains corneal transparency by preventing excess fluid accumulation in the stroma.

Each of these layers plays a specific role in the health and function of the cornea, making the accurate number of layers essential for understanding corneal anatomy and pathology.
