A magnifying cap for a prescription bottle is disclosed. The cap has a magnifying lens retained within the cap between a top aperture and an opening at the bottom end. The magnifying lens is oriented to provide a magnification of indicia carried on an outer surface of the prescription bottle, when viewed through the aperture and the opening. An illumination source may be provided around a periphery of the magnifying lens to illuminate the indicia for better viewing.

An optical lens for magnifying a reflection in a mirror is disclosed herein. The optical lens comprises a conical concave surface located on a first side of the optical lens and a conical convex surface located on a second side of the optical lens opposite the first side. An optical axis of the optical lens is formed along a central portion of the conical concave surface and a central portion of the conical convex surface. The conical concave surface has a first radius of curvature and the conical convex surface has a second radius of curvature greater in magnitude than the first radius of curvature. At least a portion of the conical concave surface is self-adherable to a mirror. When at least the portion of the conical concave surface is self-adhered to the mirror, the optical lens is configured to magnify mirror images viewed through the optical lens and the mirror.

A digital magnifier monocle may include an eyepiece, a lens, an organic light-emitting diode screen placed between the eyepiece and the lens, and a first electronic module for the generation of a digital image. The first electronic module may be placed between the screen and the lens. The monocle may also have a second electronic module placed between the screen and the first electronic module. The second electronic module may be divided into a first unit configured for the transmission of a digital image from the first electronic module to the screen, and a second unit configured for connection with an augmented reality engine and/or the transmission of said at least one digital image from the monocle to a unit outside of the monocle. The unit external to the monocle being may be designed for the storage of the image.

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 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.

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.

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.

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.

An optical attachment for surgical loupe glasses is disclosed. The optical attachment for surgical loupe glasses includes a visor sized to cover at least a portion of a first carrier lens of the surgical loupe glasses. The optical attachment also includes at least one loupe orienting feature defined by the visor.

A method is provided for adjusting a loupe including an eyepiece and a tube framework having a first optical system adjacent to an object and a second optical system adjacent to the eyepiece. At least two zoom lenses in the first optical system shift along an optical axis between a first and a second position to change magnification. The method includes shifting at least one lens in the first optical system such that a distance at which the object is focused when the zoom lenses are shifted to the first position is substantially equal to a distance at which the object is focused when the zoom lenses are shifted to the second position; and then shifting at least one lens in the second optical system along the optical axis such that the object is focused when the zoom lenses are shifted to the first position or the second position.
