ABSTRACT:
The invention relates to optical elements whose optical properties can be repeatedly adjusted over time. Through the use of modifying compositions capable of stimulus induced polymerization coupled with a blend of stimulus absorbers and initiators, it is possible to repeatedly adjust the optical properties of the element by exposing the lens to a stimulus which exceeds the absorption capacity of the stimulus absorber.
