ELECTRO-ACTIVE INSERT
First Claim
1. A lens, comprising:
- an electro-active insert comprising an optical element, wherein the electro-active insert has a thickness ranging from 50 μ
m to 1000 μ
m; and
a host lens comprising a refractive region, wherein the electro-active insert is embedded in the host lens.

Abstract
Aspects of the present invention provide multi-focal electro-active lenses having one or more multi-focal electro-active inserts. The electro-active inserts can provide multiple optical power regions each capable of providing a desired optical power. An electro-active power region of the insert is capable of providing a variable optical power upon application of an electrical signal such as a time-varying voltage waveform. Electro-active inserts can be fabricated from any type of material and can be inserted into any type of bulk lens material. The electro-active inserts can be thin and flexible and can function independently of other optical components of the overall electro-active lens. Consequently, the electro-active inserts can be fabricated according to a uniform design using uniform materials, independent of the supplementing portions of the final lens. Index matching layers of the present invention can be used to reduce reflection losses between bulk lens material and electro-active insert interfaces.
