👉 A cornea is a transparent, clear part of the eye that acts as a barrier between the internal and external surfaces of the eye. It serves several important functions:
1.
Protection
: The cornea helps to protect the eye from harmful UV rays by reflecting them back into space and preventing them from penetrating the cornea's outer layer.
2.
Vision
: The cornea is responsible for focusing light onto the retina, which in turn allows us to see colors and shapes.
