Abstract
Electro-active multi-focal spectacles are disclosed. The spectacles have a stack of at least two electro-active regions. The electro-active regions produce a plurality of viewing correction zones. The spectacles also have a controller for independently activating the electro-active regions to produce viewing correction zones. An electro-active multi-focal spectacle having a blending zone is also disclosed. The blending zone provides a transition of optical power between viewing correction zones.
