Question

why is it important for the cornea of the eye to be transparent

Answer 1

Answer:

The transparent cornea forms the anterior portion of the outer casing of the eye and has the dual functions of protecting the inner contents of the eye as well as providing about two thirds of the eye's refractive power. ... In normal corneas most of these are so thin that light scattering is minimal.

Answer 2

Answer:

More than 60% of the total refractive power of the eye is attributed to the cornea making it vital to focusing light onto the retina for visual processing [115]. For optimal vision, the cornea must efficiently transmit incident light by maintaining its transparency.
