Protect the Outer Layer of Your Eye

Your cornea is the clear outer part of your eye. Amazingly, this incredibly thin area has five layers, each with their own purpose and function:

  • Outer layer – Epithelium: protects the eyes from foreign debris; absorbs nutrients and oxygen from tears and passes those to the other layers
  • Layer 2 – Bowman’s membrane: transparent collagen layer that can respond to injury by forming a scar
  • Layer 3 – Stroma: the thickest layer that provides connective tissue for strength
  • Layer 4 – Decement’s membrane: strong tissue that protects against injury and infection
  • Layer 5 – Endothelium: keeps the fluid balance regular to keep the cornea clear

Types of Corneal Diseases

If any layer of the cornea is damaged, this can result in a corneal disease that causes distorted vision or even blindness. Some of these diseases include:

  • Keratoconus: thinning of the cornea that leads to bulging out into a cone shape
  • Corneal dystrophies: progressive disorders caused by an accumulation of abnormal material on the cornea
  • Keratitis: inflammation of the cornea
  • Ocular herpes: infection caused by the herpes simplex virus (HSV)
  • Pterygium: growth on the cornea

Corneal Shape

The shape of the cornea determines how light entering your eyes will focus in front of, behind or directly on the retina (the back of the eye). Refractive errors such as nearsightedness, farsightedness and astigmatism are due to an irregular corneal shape.
