Corneal epithelium

The corneal epithelium is the outermost layer of the cornea, the transparent front part of the eye. It acts as a protective barrier against dust, germs, and injuries, while also helping to keep the eye clear for vision. This layer is made up of thin, tightly packed cells that regularly regenerate, ensuring the eye remains healthy and functional. Its smooth surface is essential for proper light entry and focus. Overall, the corneal epithelium plays a vital role in maintaining eye health, clarity, and vision quality.
