Benefits of technology

The invention provides a pair of spectacles with a lens that has an electro-active region and an electrical contact on the edge. The lens also has a transparent wire connecting the electro-active region to the edge contact. The spectacles also have a controller and a frame, which has a contact adjacent to one of the lenses. The frame also has one or more wires connecting it to the controller. The lens and the frame are connected through a conductive elastomeric material that adheres to the lens and the frame. This invention allows for the safe and reliable electrical connection between the lens and the frame, which can enhance the functionality and comfort of the spectacles.

Problems solved by technology

The lens-frame connection can loosen over time, however.
But over time, even these connections can fail, as they rely on physical contact.

Embodiment Construction

[0026]The following description recites various aspects and embodiments of the present invention. No particular embodiment is intended to define the scope of the invention. Rather, the embodiments merely provide non-limiting examples various compositions, apparatuses, and methods that are at least included within the scope of the invention. The description is to be read from the perspective of one of ordinary skill in the art; therefore, information well known to the skilled artisan is not necessarily included.

[0027]As used herein, the articles “a,”“an,” and “the” include plural referents, unless expressly and unequivocally disclaimed.

[0028]As used herein, the conjunction “or” does not imply a disjunctive set. Thus, the phrase “A or B is present” includes each of the following scenarios: (a) A is present and B is not present; (b) A is not present and B is present; and (c) A and B are both present. Thus, the term “or” does not imply an either / or situation, unless expressly indicated....

Abstract

The present invention relates generally to electro-active optical systems, such as a pair of spectacles having one or more lenses that employ electro-active optical structures. In some embodiments, the invention relates to electro-active optical systems having a flexible electrically conductive connection between the lens and the frame.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of priority to U.S. Provisional Patent Application No. 61 / 638,290, filed Apr. 25, 2012, which is hereby incorporated by reference as though fully set forth herein.FIELD OF THE INVENTION[0002]The present invention relates generally to electro-active optical systems, such as a pair of spectacles having one or more lenses that employ electro-active optical structures. In some embodiments, the invention relates to electro-active optical systems having a flexible electrically conductive connection between the lens and the frame.BACKGROUND[0003]Certain electro-active optical systems include one or more lenses having an electro-active optical structure. In many instances, such structures lie in an interior portion of the lens, and are therefore physically removed from a control unit. In some instances, such as with a pair of spectacles, the control unit may lie in some portion of the frame or in may be ...
