Electro-active opthalmic lens having an optical power blending region
A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.
1. An optical lens system comprising:
a lens having a fixed focal length; and
an electro-active region coupled to the lens, the electro-active region having a first electro-active layer and a second electro-active layer;
wherein:
the electro-active region is adapted to, when activated in a first manner, alter a first focal length of the optical lens system to a second focal length, the second focal length different from the first focal length; and
the electro-active region is adapted to, when activated in a second manner, provide a first tint to the lens.
2. The optical lens system of claim 1 , wherein:
the first tint is electro-chromatic.
3. The optical lens system of claim 1 , wherein:
a surface of the lens is formed from a photo-chromatic material.

said optical lens system is coated with an anti-reflective coating.
14. The optical lens system of claim 1 , wherein:
the electro-active region provides the first tint to the lens by alternating a light transmission through the lens.
15. The optical lens system of claim 1 , wherein:
the electro-active region provides the first tint to the lens via application of a predetermined voltage to a gel polymer of the electro-active region.
16. The optical lens system of claim 1 , wherein:
the electro-active region provides the first tint to the lens via application of a predetermined voltage to a liquid crystal layer of the electro-active region.
