  • Patent number: 9746664
    Abstract: An apparatus includes one or more light sources configured to provide light having at least three different colors and a backlight layer configured for diffusing the light. A MEMS-based shutter layer includes a plurality of pixel elements having shutters programmably controlled to allow light from the backlight layer to pass through the shutter layer when the MEMS-based shutter is in an open configuration and to block light from passing through the shutter layer when in a closed configuration. A processor is configured to control the provision of the different colored light from the one or more light sources to the backlight layer and configured to control the passage of light from the backlight layer through the plurality of pixel elements to provide a predetermined image on the display apparatus. A hard, scratch resistant cover glass layer is stacked above the MEMS-based shutter layer.

  • Patent number: 9740026
    Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include a deformable inner portion and a deformable peripheral portion. When disposed over the optical region of an eye, the inner portion is configured so that engagement of the posterior surface against the eye deforms the posterior surface so that the posterior surface has a shape diverging form the refractive shape of the epithelium when viewing with the eye through the ophthalmic lens. The rigidity of the inner portion is greater than the rigidity of the peripheral portion and the ophthalmic lenses are configured to allow movement relative to the eye upon blinking of the eye and to be substantially centered on the optical region of the cornea following the blinking of the eye. Methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses are also disclosed.
