Abstract: An dynamic multiple focus contact lens has two transparent layers, each with a first annular electromagnet and a second annular electromagnet, a transparent pupil allowing passage of light through the layers, a core between the two layers, at least one loop antenna in communication with the electromagnets, and a transmitter for activating the electromagnets. The layers have a first shape similar to a circular segment that follows the surface of the cornea. The first shape has a first focal length, or power. Upon initiation by a user, a transmitter signals the loop antenna which energizes the electromagnets to mutually attract causing the layers to deflect and the central portion of the first layer to deform outwardly forming the layer into a second shape. The second shape has a second power, stronger than the first shape.
