Abstract: An implementation of an optical system for expanding the field of view can include a first optical element and a second optical element. The first optical element can include a first surface and a second surface. The first surface can be configured to reflect a first light beam incident on the first surface at a first incident angle greater than a first predetermined angle, and the second surface can be configured to reflect the reflected first light beam towards a location. The second optical element can include a third surface and a fourth surface. The third surface can be configured to reflect a second light beam incident on the third surface at a second incident angle greater than a second predetermined angle, and the fourth surface can be configured to reflect the reflected second light beam towards the location. Related apparatus, systems, techniques and articles are also described.

Abstract: An adapter device is provided to be disposed on the wearer's head. A mobile phone or other mobile graphical device can be inserted in the front of the device so this is opposite the user's eyes at a short distance. The device also incorporates lenses and adjustment mechanisms of the lenses that allow proper display of the graphic display device that is inserted in the adapter. Thus the device is designed to achieve stereoscopic 3D vision, configuring the adapter assembly and the device graphic as a device that allows multiplexing (two or more information channels on a single means of transmission) for position (side-by-side) in a mobile phone or other device with graphic screen TV, merging both visual content and receiving a three-dimensional image.

Abstract: The invention relates to apparatus and methods for increasing visual acuity through the use of a bioptic telescope which is at least partially embedded in a spectacle lens. In one embodiment, the telescope includes a vision lens having a vision axis and a first surface for placement substantially in front of an eye of a user. The telescope further includes a plurality of optical elements defining an optical path for viewing an object in front of the first surface. At least one of the plurality of optical elements is positioned such that at least a portion of the optical path is located within the vision lens in a plane substantially orthogonal to the vision axis.
