Wesley and Jessen worked to develop the plastic lenses known as the rigid corneal contact lens. The corneal lens fit floated on the cornea, unlike its scleral predecessor, which rested on the sclera or white of the eye and bridged the cornea.
Two researchers, Wesley and Jessen, aimed to develop a type of plastic lens for contact lenses that would rest directly on the cornea. Unlike their previous design, this new lens floated on the surface of the cornea, rather than resting on the sclera.
