Abstract
An electro-active optical cell is described including a layer of electro-active material, a front glass substrate member, and a back glass substrate member. The optical cell is capable of independently providing changeable optical power with the application of an electrical potential. The cell is also configured to be affixed to an external surface of a plastic substrate and to provide the changeable optical power, with at least one of the front substrate or the back substrate of the optical cell being an outermost optical layer. The layer of electro-active material may have a thickness less than 10 μm, and the glass substrate members may each have a thickness approximately between 20 μm and 500 μm.
