“See” cucumbers.

OK, sorry for that headline. New Scientist reports that a University of South Florida researcher has found a way to replace human corneas with sea cucumbers:

The team’s artificial cornea is made from tiny collagen fibres extracted from these sea cucumbers. When placed in a centrifuge, the fibres self assemble into layers in which the fibres are aligned vertically, a structure that is very similar to the tissue in mammalian corneas.

It’s perfectly clear.
