Abstract
Methods and devices for an oxygen permeable liquid crystal contact lens are disclosed herein. An oxygen permeable liquid crystal contact lens may include a coating. The coating may be made of one or more layers of an oxygen non-permeable material. The coating may be modified to allow oxygen to permeate though the liquid crystal contact lens to a mammalian eye.
Claims24
A liquid crystal contact lens comprising:
- a first oxygen-permeable substrate, wherein a first side of the first oxygen-permeable substrate is configured to be placed on a mammalian eye;
- a second oxygen-permeable substrate configured to be placed proximate to a second side of the first oxygen-permeable substrate to form a cavity between the first oxygen-permeable substrate and the second oxygen-permeable substrate;
- a liquid crystal material disposed within the cavity;
- and
- an oxygen-impermeable coating disposed on the second side of the first oxygen-permeable substrate facing the cavity, wherein a portion of the oxygen-impermeable coating has been removed to allow oxygen to travel directly between the liquid crystal material and the first oxygen-permeable substrate and to permeate through the liquid crystal contact lens to the mammalian eye, wherein the oxygen-impermeable coating comprises:
- a first insulating layer disposed directly on the second side of the first oxygen-permeable substrate;
- a conductive layer disposed on the first insulating layer;
- and
- a second insulating layer disposed on the conductive layer.
