Abstract:
A contact lens incorporating one or more surface modified zones on the anterior surface of the lens may be utilized to generate a friction driven rotational force when the upper and/or lower eyelids pass over the one or more regions during blinking. A small difference in the coefficient of friction between the modified and unmodified regions of the lens may result in an equivalent rotational force to that of a thickness gradient lens. This small difference in the coefficient of friction produces a means to orient and stabilize the contact lens on eye.

Claim (Index 7):
An ophthalmic device comprising:\n a contact lens having an anterior surface and a posterior surface and requiring linear translation on eye, the contact lens being formed from a first lens material; and a single modified zone incorporated at least one of into or onto the anterior surface of the contact lens, the single modified zone being configured to facilitate interaction with the lower eyelid such that an eye of the wearer is free to move under the contact lens while the lens remains stationary due to interaction of the single modified zone and a lower eyelid of the wearer, the single modified zone comprising a second lens material with a coefficient of friction greater than the first lens material by 0.1 or greater.
