An ocular optical system for imaging of imaging rays entering an eye of an observer via the ocular optical system from a display screen is provided. A side facing towards the eye is an eye-side, and a side facing towards the display screen is a display-side. The ocular optical system includes a first lens element, a second lens element, and a third lens element from the eye-side to the display-side in order along an optical axis. The first lens element, the second lens element, and the third lens element each include an eye-side surface and a display-side surface. The ocular optical system satisfies: 40°≤ω, where ω represents a half apparent field of view, which is one half the field of view of an observer.

An optical device including a first optical axis; an optical device body, notably a substantially cylindrical body; and a capture device for capturing at least a portion of the images seen by the user through the optical device; the optical device being a monocular watchmaker's loupe that can be positioned or worn in front of or close to a user's eye.

A medical magnification device, which is an example of an embodiment, comprises: a device body which has a face pad that comes into contact with the face of a user, and which covers the front of the left and right eyes of the user; a belt for fixing the device body to the head of the user; an imaging unit which has a zoom lens provided to the front of the device body, and which performs digital conversion on a magnified image obtained by the zoom lens; and a pair of monitors.

An optical system for displaying a magnified virtual image of an image emitted by a display to a viewer. The optical system includes first and second lenses facing each other and spaced apart by an air gap to define an optical cavity therebetween. The optical cavity includes a reflective polarizer disposed on a major surface of the first lens, and an optical stack disposed on a major surface of the second lens. The optical stack includes an absorbing polarizer, a first retarder layer, a partial reflector, and a second retarder layer disposed between the absorbing polarizer and the partial reflector. The first and/or second lenses is/are birefringent lens provided outside the optical cavity to control polarization.

A device including a compartment section, wherein the compartment section is configured to host ID or cards; a bottom wall disposed on a proximate bottom portion of the compartment section; at least three or more closed sidewalls and an open sidewall generally surrounds the compartment section, wherein the open sidewall is configured to be operable for accepting a magnifying lens; a magnifying lens, the magnifying lens is configured to magnify the ID or card for viewing; an open area disposed on a proximate top portion of the compartment section, wherein the open area is configured as an entry point of the ID or card; a base section that is configured to support the device against a surface area; and a U-shaped bracket implement that is configured to be operable for engaging the compartment section to the base section.

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.

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.

An electronic loupe (400) features a view piece (401) mounted to a headpiece (405) by a linkage (406). A camera (402) and LED light (403) are mounted (404) in front of the view piece (401) to provide an image in the view piece (401) on displays (not shown) for the user. A control box (410) may be wired to the electronic loupe, or wirelessly connected, or the controls for the electronic loupe may reside on the view piece (401) and the headpiece (405). Other controls, such as a remote control or a foot pedal, are also disclosed. Illumination controls and location are designed for ideal illumination along various spectra. Automatic recording and documentation is also provided.

A packing structure including a first packing component, a second packing component, and two lenses is provided. The second packing component is adapted to be combined with the first packing component detachably, such that a containing space is formed between the first packing component and the second packing component. The containing space is adapted to contain an electronic device. The two lenses are disposed on the second packing component. An image displayed by a display surface of the electronic device is adapted to be transmitted to outside of the containing space through the two lenses, so as to form a virtual reality image.
