A field-of-view transformation structure of a head-mounted magnifying-glass comprises: a wearing-piece, a supporting-assembly, a first pivoting-portion, a magnifying-glass main-body, a first prism main-body, and a second prism main-body; wherein the supporting-assembly is set with the wearing-piece, the first pivoting-portion is defined on the supporting-assembly, the magnifying-glass main-body and the first pivoting-portion are pivotally set mutually, a first facing-eye-surface is defined on the first prism main-body corresponding to the magnifying-glass main-body, and a second facing-eye-surface is defined on a offset position of the magnifying-glass main-body; thus, the user can wear the wearing-piece, when wanting using the first prism main-body to watch, the magnifying-glass main-body can be flipped upwards; or, the user can directly view the second facing-eye-surface to simultaneously watch other parts of the patient when watching the magnifying-glass main-body. Besides the magnified field-of-view is bigger than the conventional technology, it also has the advantage of wide-angle field-of-view.

An above-liquid refraction-correcting buoyant lens device is described. The above-liquid refraction-correcting buoyant lens device includes a viewing portion and a buoyant portion. The viewing portion includes optically transparent material. The buoyant portion can be disposed around an outer edge surface of the viewing portion. In some embodiments, the viewing portion has a viewing area of at least twenty-five square inches. In some embodiments, the viewing portion includes a magnification lens.

A display apparatus including a left portion corresponding to a left eye of a user and a right portion corresponding to a right eye of the user, each portion includes at least one image capturing unit configured to capture an image of a physical space, and a display unit configured to display a video image based on a captured image obtained by the image capturing unit. The image capturing unit is arranged on an inside of an angle formed by lines extending from the pupil of the corresponding eye to each side of the display unit.

A wearable device that aids vision of a person is disclosed that includes a display system including a display device, a first polarizer parallel to the display device, a quarter waveplate, and a mirror. The display device, the first polarizer, the quarter waveplate, and the mirror are arranged sequentially such that the display device is disposed at a first end of the display system and the mirror is disposed at a second, opposite end of the display system. The display system has a length corresponding to a focal length of the mirror. A camera system includes a camera and an image stabilization system with a zoom magnification configured to provide up to at or about 60 times zoom. The display system and the camera system are secured to a mount and are movable relative to each other about the mount. The mount is secured to a frame.

A crystal/glass or screen of an apparatus intended to display an information visible to a user includes on its outer surface a transparent protective film with a convex outer surface, constituting a lens in order to facilitate reading. The transparent protective film constituting a lens is a layer (2) of transparent sapphire glass material having an anti-scratch surface. This layer (2) includes a convex outer surface forming a lens and an inner surface carrying a transparent repositionable glue film (4) by which said layer (2) can be removably glued to the outer surface of the crystal or of the screen (1).

The image display device includes an image generating unit that emits first image light, a pupil expanding element that expands a diameter of a light flux included in the first image light from the image generating unit to obtain second image light, a first light condensing optical system that condenses the second image light and forms an intermediate image, and a second light condensing optical system that condenses light from the intermediate image and generates a virtual image on eye of a viewer, in a plane including at least the image generating unit, the pupil expanding element, and the eye of the viewer, a maximum emission angle of the first image light is smaller than a maximum viewing angle of the virtual image, and the diameter of the light flux included in the second image light is greater than that of a light flux included in the virtual image.

A device for mixed reality includes a base, a curved mirror, a first holder, and a second holder. The curved mirror has a concave surface, a convex surface opposite to the concave surface, and a light transmissive medium between the concave surface and the convex surface. The first holder is disposed on the base, disposed in front of the concave surface and within a focal length of the curved mirror, and configured to support a portable apparatus to be oriented at an angle. The second holder is disposed on the base and supports the curved mirror to face the portable apparatus.

A smart phone magnifier assembly for magnifying imagery displayed on a smart phone includes a magnifying screen that has a width ranging between approximately 3.0 inches and 5.0 inches and a length ranging between approximately 5.0 inches and 8.0 inches. In this way the magnifying screen can fit on a screen of a smart phone thereby facilitating the magnifying screen to magnify and thusly enhance visibility of imagery displayed on the screen. An adhesive layer is bonded to the magnifying screen for adhesively engaging the smart phone screen. Thus, the adhesive layer releasably retains the magnifying screen on the smart phone screen.

The image display device includes an image generating unit that emits first image light, a pupil expanding element that expands a diameter of a light flux included in the first image light from the image generating unit to obtain second image light, a first light condensing optical system that condenses the second image light and forms an intermediate image, and a second light condensing optical system that condenses light from the intermediate image and generates a virtual image on eye of a viewer, in a plane including at least the image generating unit, the pupil expanding element, and the eye of the viewer, a maximum emission angle of the first image light is smaller than a maximum viewing angle of the virtual image, and the diameter of the light flux included in the second image light is greater than that of a light flux included in the virtual image.
