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).

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.

There is provided a practically useful display method that allows viewers to see in-focus images easily. The method includes the steps of providing a lens array including a plurality of lenses, providing display areas at least one of which corresponds to each of the plurality of lenses, displaying partial images of an original image in the display areas respectively, the partial images being different from one another but partially including a same image portion, forming a bundle of beams by beams respectively emergent from the plurality of lenses equivalently, forming virtual images of the respective partial images displayed in the respective display areas by the respective lenses, and forming a single virtual image by superposing the virtual images of the partial images displayed in the respective corresponding display areas formed by the plurality of lenses.

A sun visor assembly including a visor body and a mirror panel pivotally connected to the visor body. The mirror panel includes a first mirror oriented in a first direction and a second mirror oriented in a second direction. The two mirrors have different magnification factors.

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, where represents a half apparent field of view, which is one half the field of view of an observer.

A magnification application for use with augmented reality (AR) eyewear devices. The magnification application enables a user of an eyewear device to activate a magnification overlay on a display whenever a camera on the eyewear device detects that the field of view includes a registered virtual marker. The magnified overlay includes one or more frames of the captured video data, presented according to a predefined and configurable magnification power. A pointer including a vector and a visual tether guides the user toward the virtual marker. When the eyewear device location is near a perimeter associated with the virtual marker, the magnified overlay appears in a predefined and configurable frame on the display.
