A hands-free binocular device. A pair of eyeglasses has two temples. A telescopic section is mounted to each eyeglass temple. The hands-free binocular device includes lenses for magnifying images and light path redirecting devices for controlling the light path to the eyeglass lenses. Light from an image being observed flows through the magnifying lenses and is redirected by the light path redirecting device. The image is magnified and viewable by a user. The user can shift his gaze upward to view the magnified image or look down from the magnified image to view a non-magnified image. In one preferred embodiment the light path redirecting devices are prisms. In another preferred embodiment the light path redirecting devices are mirrors.

Provided are stereoscopic eyeglasses capable of reducing visual fatigue in binocular stereoscopic display by a simple configuration. In stereoscopic eyeglasses, in order to expand a tolerance of match between vergence and accommodation enabling comfortable stereovision in eyeglasses-using stereoscopic display, wide-focus lenses ranging in focal length are incorporated so as to overlap optical filters in light transmission directions, and accordingly, visual fatigue to be caused by vergence-accommodation conflict during stereoscopic image observation is reduced.

A method for pairing of shutter glasses (411-414) with a remote control unit (RCU) (461-464, 272-273) for use with a display device (220, 230) configured to display a plurality of video streams by time interleaving the frames of the video streams and sending synchronization signal to shutter glasses. The method comprises the steps of: generating at least one synchronization signal (911, 912; 921, 922; 913, 923) for the shutter glasses (411-414); receiving an IR signal (331B) from the RCU (461-464, 272-273); comparing the temporal correspondence of the received IR signal (331B) with the generated at least one synchronization signal (911, 912; 921, 922; 913, 923); and in case a temporal correspondence is found, pairing the RCU (461-464, 272-273) with the shutter glasses (411-414) for which the correspondent synchronization signal (911, 912; 921, 922; 913, 923) was found.

Three-dimensional display systems may include polarized displays that polarize light emitted from a first set of areas of the display with a first polarization for a first eye of the viewer and that polarizes light emitted from a second set of areas of the display with a second polarization for a second eye of the viewer. This may result in dark areas being perceived by a viewer when viewed through polarized 3D glasses. Systems and technologies according to this disclosure may include 3D glasses that have a lenses configured to redirect a portion of incoming light in a first axis to at least partially illuminate the dark areas.

An eyewear device that adjusts an on time and an off time of a pair of cameras to control heat of the cameras and of the eyewear device.
