Patent ID: 7452075

Claim:
A soft contact lens comprising: a disc-shaped body having a central portion selectively providing visual correction when worn by a person; a fluid reservoir having an opening and holding a fluid, said fluid reservoir being collapsible and being formed in said body away from said central portion and positioned to be selectively pressurized and depressurized by the person's eye lid as the person gazes downward and forward, causing said fluid reservoir to collapse when pressurized causing the fluid to exit through said opening, said fluid returning to said fluid reservoir when said fluid reservoir is depressurized; and a chamber with a micro-channel disposed in said central region and being in communication with said fluid reservoir through said opening, said chamber being selectively filled with said fluid as said fluid reservoir collapses, said micro-channel being arranged and constructed to change the optical characteristics of the lens by changing the curvature of said central region in response to changes in the pressure of said reservoir.
