An accessory for use with a phone or tablet computer. The accessory connects to the phone, either by enveloping the phone with a case-like element or clipping to the side of the phone with a clip. A hinged lens covers at least a portion of the screen and pivotally connects to the connection portion. This lens can be tilted up from the screen to increase the effective prescription of the lens, enlarging the text and images on the screen of the phone, or can be tilted back down towards the screen to reduce the effect.

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.

A packing structure including a first packing casing, a second packing casing, and two lenses is provided. The second packing casing is adapted to be combined with the first packing casing detachably, such that a containing space is formed between the first packing casing and the second packing casing. The containing space is adapted to contain an electronic device. The two lenses are disposed on the second packing casing. An image displayed by a display surface of the electronic device is adapted to be transmitted to outside of the containing space through the two lenses, so as to form a virtual reality image.

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.

An optical system includes, from an image side to an object side, a first lens having a positive refractive power, a second lens having a positive refractive power, and a third lens having a negative refractive power. The first lens, the second lens, and the third lens form an optical path with the object side facing a screen and the image side adapted to provide an image from the screen to a user. In one aspect, the optical system is adapted to correct at least one of a group of aberrations including astigmatism and field curvature; or, lateral color.

A See-Through Display System with the ability to correct visual deficits such as presbyopia, color blindness and poor night vision is disclosed. This invention enables the correction of visual deficits using camera(s), microdisplay (s), controlling circuit(s) with digital grayscale control and see through optics such as free form lens/mirror, half-mirror, diffractive and/or holographic optical element(s).

A display apparatus including a left portion corresponding to a left eye of a user and a right portion corresponding to a right eye of the user, each portion includes at least one image capturing unit configured to capture an image of a physical space, and a display unit configured to display a video image based on a captured image obtained by the image capturing unit. The image capturing unit is arranged on an inside of an angle formed by lines extending from the pupil of the corresponding eye to each side of the display unit.

A viewing system includes a first optics system having a first aperture size and a first field of view, and optics that provide a lightpath to a first sensor. The optics system has a second optics system having a second aperture sized to be less than the first aperture size, and a second field of view greater than the first field of view; the second optics system providing a lightpath to a second sensor. Also provided is a display switchable between a first view mode in which a wide field image provided by the second sensor is displayed, and a second view mode in which a narrow field image provided by the first sensor is displayed.

A lens assembly includes at least three lens elements. One lens element closest to an imaged object of the lens elements is a first lens element, which is made of an electromagnetic radiation absorbing material.

A method and a mirror selectively magnify an image reflected by a discrete portion of a reflective area of the mirror while an image reflected by the remainder of the reflective area outside the discrete portion remains unchanged. A light-transmitting area is placed within the reflective area, outside of and adjacent to the discrete portion, and a light source is located for directing light through the light-transmitting area to illuminate a space adjacent to and confronting at least the discrete portion of the reflective area.
