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.

A multifunctional case for cell phones, tablets, and other personal electronic devices with flip, sliding, and adjustable magnifying lens for viewing a screen is disclosed. The multifunctional case includes options with a detachable lens and a handle, allowing a user carrying a smartphone or similar personal electronic device mounted in the multifunctional case an immediately available means to magnify print on objects, giving the user various ways to eliminate many occasions where reading glassed are needed.

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.

Provided is an ophthalmic observation/illumination set for adjusting illumination conditions and a working distance to the object of observation and illumination. set consists of a main optical lens and a couple of interchangeable illumination members that can be assembled in various combinations with the main optical lens so that a light emitted from one of the illumination members will intersect the optical element of the main optical lens or will pass to the object around the optical element of the main optical lens. The set also contains a common handle with batteries for supply of power to the illumination member connected to the main optical lens and an additional optical component such as a Barlow lens selected from a set of Barlow lenses of different curvatures or a fisheye lens.

A magnifying screen protector is affixed to a touchscreen device with or without the use of a rugged case. The protector improves upon visual clarity of a screen of the touchscreen device. The protector improves upon the durability of the screen of the touchscreen device without degrading a user's experience.

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.
