Abstract

The present invention provides a contact lens manufactured at least partially from an intelligent polymer, the lens having a relaxed state which, upon application of a first stimulus forms a first corrective shape and which, upon application of a second stimulus, forms a second corrective shape, wherein the corrective effect provided by the lens in the relaxed state is intermediate to the corrective visual effects provided by the first and second corrective shapes.
