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.
