Epithelium

There are only .45mm to .6mm of cell layers standing between your eyes’ overall happiness and unhappiness. These five layers, called the epithelium, form the transparent, protective barrier that keep the cornea in good health. Acting as the primary refractive “lens” surface, these cells control how much water, salts, and chemicals pass into the cornea, making it a natural antibiotic against bacterial infections. When the epithelium is kept lubricated, smooth and healthy, the result is clear, problem-free vision.
