A jewelry setting has a magnifying lens in a lens holder for supporting the magnifying lens. A precious stone arrangement is supported by a precious stone setting for supporting the precious stone arrangement below the magnifying lens, at such position relative to the magnifying lens as to produce a magnified image of the precious stone arrangement at a top surface of the magnifying lens. A mechanical coupling is configured to couple the precious stone setting to the lens holder. The setting can be implemented as any type of jewelry item, e.g. a finger ring, a necklace, a pendant and the like.

A viewer for viewing an object under magnification, the viewer comprising: an objective lens for producing an image of an object located at an object plane and having a radial extent defined by an aperture stop; a partially-transmissive reflector for allowing transmission of light therethrough from the objective lens to a mirror arrangement and providing for reflection of light which is returned thereto from the mirror arrangement; a mirror arrangement which receives a light component from the partially-transmissive reflector, and is located such that a focussed image of the object is produced at the mirror arrangement and light received by the mirror arrangement is reflected back to the partially-transmissive reflector and relayed to produce an image of the object; a viewing lens arrangement for producing an optical image of the object which is viewable by an observer at an exit pupil at a viewing plane; wherein the objective lens has a beam path angle (a) as defined by a distance from the object plane to the objective lens and a radial extent of the aperture stop; wherein the viewer has a viewing angle () as defined by a distance along an optical axis from the mirror arrangement to the viewing plane and a radial extent of the exit pupil at the viewing plane; wherein the viewer is configured such that a displacement ratio of the beam path angle (a) to the viewing angle () is at least 3:1, whereby the observer is provided with a greater change in depth perception of the object being observed relative to an extent of displacement of a head of the observer.

A display device is provided. The display device includes a display module and a cover lens. The display module has a display area and a non-display area aside the display area. The cover lens which is disposed on the display module and covers the same includes a convex lens portion and a cover portion, wherein the convex lens portion has a convex cover surface facing the display area, the cover portion is connected to a side of the convex lens portion opposite to convex cover surface; the cover portion also has a fringe extending outsides the convex lens portion. The cover portion has an outer surface which includes a central area and a cambered surface connected to the central area and corresponding to the fringe.

A magnification device including a housing having a distal open end and a proximal open end is disclosed. The housing includes an optical system including one or more objective lenses adjacent the distal open end, and one or more eye lenses adjacent the proximal open end, the optical system produced a desired level of magnification; and a filtering system having first filter selectively filtering a first group of wavelengths and a second filter selective filtering a second group of wavelengths. The first and second filters having an optical density selected based on a magnification level of the optical system. A vision enhancing assembly including a carrier device and one or more magnification devices coupled to the carrier device is also disclosed, wherein the magnification devices include filters that have optical densities based on a magnification level.

Provided herein are disclosures relating to systems and methods of detangling jewelry. The jewelry detangling system may include a body, the body further including a cavity and a plurality of arms located in a cavity of the body and operably coupled therein. The plurality of arms further include corresponding beds dimensioned to receive jewelry pieces thereon during the detangling process. A magnifier including a frame and a lens may be coupled to the body of the jewelry detangler and rotatable about a hinge thereon about a plurality of positions.

In order to obtain an observation optical system which has high optical performance while having a wide field of view, and can easily reduce variation of aberration at the time when an eye relief has changed, the present invention provides an observation optical system which is used for an observer to observe an image displayed on an image display surface, and includes in order from an observation side to an image displaying surface side: a first lens having a positive refractive power; a second lens having a negative refractive power; and a third lens having a positive refractive power, wherein a focal length f1 of the first lens, a focal length f2 of the second lens and a focal length f3 of the third lens are each appropriately set so as to satisfy the conditional expression of: $0.40<\frac{f1}{\sqrt{-f2f3}}<0.80.$

An interactive element for use with an interactive touch screen comprises a conductive body element and a lens. The conductive body element is adapted to interactively engage the interactive touch screen. The lens is supported by the conductive body element. The conductive body element supports the lens relative to the interactive touch screen such that light emitted by the interactive touch screen enters a first portion of the lens and is visible at a second portion of the lens. The conductive body interacts with the interactive touch screen to cause the interactive touch screen to emit light such that light enters the first portion of the lens.

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.
