Abstract:
1. An ophthalmic device comprising: a contact lens requiring rotational stability when on an eye, the contact lens being formed from a lens material; and at least one dynamic stabilization zone formed within a cavity in the contact lens, the at least one dynamic stabilization comprising a second material that redistributes and changes shape within the cavity under eyelid pressure at eye temperature, the at least one dynamic stabilization zone forming an angle of contact with the eyelids wherein the angle of contact between the at least one dynamic stabilization zone and the eyelids changes when the eyelids move across the at least one dynamic stabilization zone by changing the shape of the second material such that the angle of contact between the eyelids and the at least one dynamic stabilization zone increases during blinking thereby increasing the rotational force acting on the contact lens until the eyelids are substantially in contact with one another thereby flattening the second material comprising the at least one dynamic stabilization zone.
