A viewing system and method for producing at least one image for being perceived as three-dimensional, including at least one of: a provision for compensating the center-of-interest of the at least one image in such a manner as to reduce convergence-accommodation conflict; a provision for configuring the viewing system such that crosstalk produced by a stereo display is perceived as foreground and background blur instead of ghosting; and a provision for viewing the at least one image via automicrostereopsis.

The invention relates to an artificial intra ocular lens of variable optical power, comprising at least two optical elements which can be shifted relative to each other in a direction extending perpendicular to the optical axis wherein the optical elements have such a shape that they exhibit, in combination, different optical powers at different relative positions. This results in a construction which has such a low weight that it is applicable as an intra ocular lens of adjustable optical power. According to a first preferred embodiment the lens comprises positioning means the optical elements in the eye and driving means, which can be operated by the user to execute a movement of at least one of the optical elements relative to the other optical element. This embodiment can be used to correct the accommodation function.

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.

Provided are an eye accommodation distance determining device. The eye accommodation distance determining device includes: an interferometer configured to generate a plurality of frequency modulated laser beams in different directions and to generate a plurality of interferometric signals using laser beams reflected from eye reflecting surfaces, a signal processing unit configured to generate a signal spectrum using each of said plurality of interferometric signals, a distances determining unit configured to determine distances to the eye reflecting surfaces for each of said plurality of laserbeams, a points coordinates determining unit configured to determine coordinates of points on each of the eye reflecting surfaces for each of the laser beams, a reconstruction unit configured to generate an eye inner structure model based on the determined coordinates of points, and an eye accommodation distance determining unit configured to determine, based on said eye inner structure model, aneye accommodation distance.

Systems and methods may provide for capturing 360 degree video, and multi-resolution encoding, processing and displaying of the video based on a field of view (FOV) and region of interest (ROI) for a viewer. The ROI may be determined based on eye tracking information (ETI) and the video may be encoded for viewports within the FOV at a high resolution and for other viewports outside the FOV at a lower resolution. ROI in the video may be encoded at a high resolution and areas outside of the ROI may be encoded at a lower resolution. The ETI enables the selective display of one or more warnings based on the gaze of a user to improve the efficiency of the warning. 3D glasses having variable lens may be used to adjust the focal distance of a virtual display to match a virtual distance of an object based on stereo distance cues.
