Paragon Z CRT contact lenses are manufactured from Menicon Z® (tisilfocon A).

The lens design also includes a convex elliptical edge terminus smoothly joining the anterior and posterior surfaces. Paragon Z CRT Contact Lenses for Corneal Refractive Therapy are to be worn overnight with removal during all or part of each following day. The lens material (tisilfocon A) is a thermoset copolymer derived from fluoro-methacrylate and siloxanylstyrene bound by crosslinking agents.

A UV absorber (Benzotriazol) is added as an additive during the manufacturing process. FDA UDI
