The cornea is the clear, dome-shaped front surface of the eye that plays a vital role in vision. It acts as the eye’s outermost lens, helping to focus light onto the retina so that clear images can be formed. Although transparent and seemingly simple, the cornea is a highly specialized structure responsible for a significant portion of the eye’s focusing power.
Because the cornea is constantly exposed to the external environment, it can be affected by injuries, infections, and various diseases. Maintaining corneal health is essential for preserving clear vision and overall eye function.
