Abstract: A system and methods for contrast sensitivity compensation provides for correcting the vision of users whose vision is deficient for discerning high spatial frequencies. The system and methods use measurements of the user's contrast detection as a function of spatial frequency in the image to correct images in real time. The system includes a head-mountable device that includes a camera and a processor that can provide enhanced images at video framing rates.

Abstract: A system and methods for compensating for retinitis pigmentosa for a user include using a head-mounted and user-controllable device that can minify the image to more closely match the user's reduced field of view. The user may adjust the amount of minification and may also adjust the magnification of the image.

Abstract: A head-mounted video camera, a processor, and a display are integrated within the head-mounted device worn by the user. The head-mounted device is configured to capture images of the environment and subject those images to specialized processing in order to diagnose and/or make up for deficiencies in the user's eyesight. Different modes of operating the device are provided that enable the user to configure the device for a specific application. The modes of operation include at least an assistive mode, a diagnostic mode, and a therapeutic mode. Each mode of operation may include further options, where each option is dedicated to a specific processing approach specific to a condition that may afflict the user, ranging from contrast sensitivity issues to strabismus.

Abstract: The present disclosure provides neuromodulators, nucleic acid encoding thereof, and compositions thereof for endowing visual processing abilities to neuronal cells. The present disclosure further provides a method of restoring light sensitivity to degenerate retinas.

Abstract: A system and method is presented for the enhancement of a user's vision using a head-mounted device. The user is presented with an enhanced view of the scene in front of them. One system and method reduces the glare from lights or the sun. Another system and method provides increased contrast for the darkest parts of a scene.

Abstract: A method, device and system for stimulating visual tissue, typically in the retina or visual cortex, to achieve an artificial percept of light or image. The method includes providing stimulating electrodes suitable for placement in proximity to the visual tissue and generating a series of short-duration stimulation signals having a duration of less than about 0.5 milliseconds each. The short-duration stimulation signals are applied through the stimulating electrodes with varying frequencies that are substantially matched to a spiking range of frequencies of at least one ganglion cell for perceiving brightness or image.
