Abstract

Contact lenses, methods and systems for accomplishing the requirement for biocompatibility of oxygen delivery to the eye, and the cornea in particular, when elements and components are used which reduce the transmissibility of oxygen and which require coverage of a significant area of the non-vascularized cornea. A contact lens assembly is provided, comprising: an anterior surface, a posterior surface and at least one element or component having a substantially low oxygen permeability disposed within the lens. The contact lens also includes a layer having an oxygen permeability greater than the aforementioned element or component. The thickness of this layer is such that the layer provides an equivalent oxygen percentage to the cornea beneath the aforementioned element or component.
