Abstract:
A Free-form contact lens and method of making the same. The lens includes a posterior optical quality surface having a concave shape, an opposing anterior surface having a convex shape both of which join at a lens edge that defines an outer periphery of the contact lens, and at least a first lens feature having a predetermined shape and made of a first polymerized Reactive Mixture. The remainder of the lens is made of a second polymerized Reactive Mixture that is different than the first polymerized Reactive Mixture, and that is covalently bonded thereto.
