Disclosed is a magnifying glass for skin diagnosis capable of acquiring a distortion-compensated skin image, and more particularly a magnifying glass for skin diagnosis capable of acquiring a magnified skin image and at the same time compensating for distortion occurring at the time of acquisition of the magnified skin image to provide an observer with a distortion-compensated, magnified skin image, thereby improving visibility, and therefore the observer can more clearly and vividly observe the skin. The magnifying glass includes an optical/light radiation structure, a light emission controller, and a housing.

A face shield adapted to protect the face from biohazards during medical procedures is disclosed. The central portion of the face shield includes a horizontally centered cut out that extends downwardly from a top edge or top portion. The cut out is sized and positioned to allow a loupe light to pass through. The face shield includes two or more post openings for use in coupling the shield to a shield frame. The shield frame is worn about the user's head without relying on attachment to a pair of loupes (if worn). The shield has left and right side portions that extend along and attach to posts along the sides of the frame.

A device for variable polarization by an illumination device for illuminating organic tissue. The device includes a first set of one or more light emitting diodes (LEDs), a first polarizer arranged to polarize light emitted from the first set of LEDs in a first polarization direction, a second set of one or more LEDs, a second polarizer arranged to polarize light emitted from the second set of LEDs in a second polarization direction. A lens is arranged to collect light from organic tissue illuminated by the first and/or second sets of LEDs including a viewing polarizer arranged to polarize the light collected from the organic tissue in the second polarization direction. A signal generator is operable to signal one or more drivers for driving one of the first and second sets according a signal value and driving the other of the first and second sets according to an inverse value thereof.

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 device can include glasses including one or more lenses that permit a wearer a broad view of the environment from a first perspective and contact members having one or more contact-surfaces formed to secure the glasses to a head of the wearer while the wearer is wearing the device. The device can include one or more loupes, each loupe including a redirection member structured to redirect image light that is received by the loupe; one or more magnifying members structured to magnify the image light; a viewport structured to allow passage of the magnified image light. The loupe is secured through one of the lenses such that the magnified image light is presented though the viewport to an eye of the wearer while the wearer is wearing the device.

A surgical loupe system includes one or more polarization filters for producing and/or blocking polarized light. A light source is directed through a polarization filter to a patient's tissues, producing returned light. The returned light may be magnified.

Optical systems and apparatuses configured for enabling substantially simultaneous observation of a plurality of points in an array from a common reference point. Without the optical systems and apparatuses disclosed herein, less than all of the plurality of points can be observed substantially simultaneously from the common reference point.

A cover for a display screen is disclosed herein. The cover includes a lens layer and a protective layer. The cover is for attachment to a display screen of an electronic device, particularly a cell phone. The lens layer includes a corrective means such as a prescription lens configured to assist users in viewing their phone screen without glasses/lenses.

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.

Disclosed herein is a sensor loupe where the user can look at a gemstone through a passive optical loupe and take a picture of the exact field of view that he sees.
