Methods and devices for improving visual perception in challenging vision environments and for some with low vision conditions (including age related macular degeneration, AMD) are disclosed. A plurality of frequently co-pathological conditions that together make undistorted, clear and bright vision challenging are dealt with by managing the nature, amounts and patterns of light reaching the eyes while managing the sensitivity and dynamic ranges of the eyes. For example, the sensitivity of chromophore response to particular wavelengths and the instant status of the visual transduction system are, in some embodiments, measured, monitored and managed.

A display apparatus for presenting three-dimensional imagery, including an optical combiner having a first side, a second side, a third side and a fourth side. The second side is opposite to the first side and the fourth side being is opposite to the third side. Optical combiner further includes a first semi-transparent reflective portion arranged to reflect light incoming from the first side towards the fourth side and a second semi-transparent reflective portion arranged to reflect light incoming from the second side towards the fourth side. Light incoming from the third side passes through the first semi-transparent reflective portion and the second semi-transparent reflective portion towards the fourth side. The display apparatus further includes of a first display, a second display and a third display arranged at a first distance, a second distance and a third distance from the first side, the second side and the third side of the optical combiner, respectively, wherein a first image, a second image and a third image rendered at the first display, the second display and the third display are presented at a first focal distance, a second focal distance and a third focal distance, respectively, thereby creating the three-dimensional image.

An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity. Advantageously, the wavefront divergence, and the accommodation cue provided to the eye of the user, may be varied by appropriate selection of parallax disparity, which may be set by selecting the amount of spatial separation between the locations of light output.

Optical devices based on novel components for selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the previous (parent) patents are herein made both more useful in practical day-to-day use and more widely applicable to improving the ability of a user to perceive visual stimuli.
