Limbus (Corneal-Scleral Border / Limbal Region)
The limbus (limbal region) is the border between your clear cornea and white sclera. This small area contains stem cells that repair and renew your cornea. The limbus is also where your eye gets its blood supply. Protecting your limbus keeps your cornea healthy and maintains good vision.
