  • Publication number: 20130035760
    Abstract: A lens in accordance with the present invention includes an accommodating cell having two chambers with at least one chamber filled with optical fluid with the refractive index matching the refractive index of the accommodating element separating them. The accommodating element has a diffractive surface with surface relief structure that maintains its period but changes its height due a pressure difference between the chambers to redirect most of light that passes through the lens between different foci of far and near vision. The invention also includes a sensor cell that directly interacts with the ciliary muscle contraction and relaxation to create changes in pressure between the accommodating cell chambers that results in changing surface relief structure height and the lens accommodation.

  • Patent number: 8333470
    Abstract: A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

  • Publication number: 20120281181
    Abstract: Methods of eye gaze tracking are provided using magnetized contact lenses tracked by magnetic sensors and/or reflecting contact lenses tracked by video-based sensors. Tracking information of contact lenses from magnetic sensors and video-based sensors may be used to improve eye tracking and/or combined with other sensor data to improve accuracy. Furthermore, reflective contact lenses improve blink detection while eye gaze tracking is otherwise unimpeded by magnetized contact lenses. Additionally, contact lenses may be adapted for viewing 3D information.

  • Publication number: 20120206691
    Abstract: An dynamic multiple focus contact lens has at least one transparent layer with a first annular electromagnet and a second annular electromagnet, a transparent pupil allowing passage of light through the at least one layer, at least one loop antenna in communication with the electromagnets, and a transmitter for activating the electromagnets. The at least one layer has 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 sends a signal to the loop antenna which energizes the electromagnets to mutually attract causing the at least one layer 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.

    Abstract: A vision prosthesis includes a first detector disposed to detect a polarization state of light reflected from a retina, and a controller in communication with the first detector. The controller is configured to receive, from the detector, a measurement signal indicative of the polarization state. In response thereto, the controller generates a control signal for causing a change to an optical property of an optical system in optical communication with the retina.
