Abstract
A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.
Claims12
A lens, comprising:
- an adaptable component containing a power supply, a controller, an activable element, and a plurality of conductive traces, wherein the adaptable component is capable of providing a functionality to the lens, and wherein a set of control signals is capable of customizing the functionality;
- and
- a flexible lens base, wherein the flexible lens base is in contact with at least a portion of the adaptable component.
An electrically switchable, flexible contact lens for conforming to an eye of a user, the electrically switchable, flexible contact lens comprising:
- a first liquid crystal cell for changing a focal power of the electrically switchable, flexible contact lens, and having a cell gap thickness between a first inner surface and a second inner surface, the first liquid crystal cell comprising a diffractive optical element for correcting vision of a user,
- wherein the diffractive optical element is arranged to maintain the cell gap thickness by providing support at one or more locations within the first liquid crystal cell.
An electrically switchable, flexible contact lens for conforming to an eye of a user, the electrically switchable, flexible contact lens comprising:
- a first liquid crystal cell for changing a focal power of the electrically switchable, flexible contact lens, and having a cell gap thickness between a first inner surface and a second inner surface, the first liquid crystal cell comprising a diffractive optical element for correcting vision of a user, the diffractive optical element comprising an inner portion and an outer portion, a height of the diffractive optical element at the outer portion being different than the height of the diffractive optical element at the inner portion.
