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.

Some implementations of the disclosure are directed to tessellating a light field into a size or depth that is larger or further extended than the pupil size of an imaging system or display system. In some implementations, a display system comprises: a display configured to emit light corresponding to an image; a first optical component positioned in front of the display, the first optical component configured to pass the light to an orthogonal field evolving cavity (OFEC) at a plurality of different angles; the OFEC, wherein the OFEC comprises a plurality of reflectors that are configured to reflect the light passed at the plurality of different angles to tessellate the size of the image to form a tessellated image; and a second optical component optically coupled to the OFEC, the second optical component configured to relay the tessellated image through an exit pupil of the display system.

A display device includes: a display panel including an active region, an inactive region disposed adjacent to the active region, and a first alignment mark, wherein a plurality of sub-pixels are disposed in the active region, and the first alignment mark is positioned at a first distance in a first direction from an alignment reference pixel disposed adjacent to a boundary of the active region; and an optical member including a plurality of lenses and a second alignment mark, wherein the plurality of lenses are disposed to be inclined at a first angle with respect to a direction in which the plurality of sub-pixels are arranged, and wherein the second alignment mark is positioned at the first distance in the first direction from the alignment reference pixel and is positioned at a second distance in a second direction, crossing the first direction, from the first alignment mark.

A varifocal system comprises a stacked first-type liquid crystal (LC) lens structure and a stacked second-type LC lens structure in optical series. The stacked first-type LC lens structure includes a plurality of first-type LC lenses, and a first-type LC lens provides continuously variable optical states in a first step resolution. The stacked second-type LC lens structure includes a plurality of second-type LC lenses and provides a plurality of optical states in a second step resolution. The first step resolution is smaller than the second step resolution, such that when the stacked second-type LC lens structure is switched between two optical states, the first-type LC lenses provide a continuous adjustment of optical power between the two optical states. The stacked first-type LC lens structure and the stacked second-type LC lens structure together provide a continuous adjustment range of optical power for the varifocal system.

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.
