The cornea, a transparent outer layer of the eye, plays a crucial role in vision. It acts as a protective barrier, shielding the eye from external elements. Additionally, the cornea is responsible for focusing light onto the retina, aiding in the formation of a clear and sharp image. As light enters the eye, the cornea refracts or bends it, contributing significantly to the eye’s overall optical power. Its precise curvature and transparency are essential for proper light transmission, enabling the retina to capture visual information. Ultimately, the cornea’s functions are pivotal in maintaining visual acuity and clarity in the human eye.
