  • Publication number: 20240138668
    Abstract: Provided is a method, performed by an augmented reality (AR) device, of measuring a user's vision. The method includes: obtaining, by using a camera of the AR device, a background image including an image of at least one physical object; identifying an edge of the image of the at least one physical object in the background image; determining a first region for measuring the vision of the user on the background image based on the edge of the image; determining a second region corresponding to the first region on a display of the AR device; outputting a virtual object for measuring the vision of the user to the second region; obtaining a user input signal for vision measurement after the outputting the virtual object; and determining a vision prescription value of the user based on the user input signal.

  • Publication number: 20230404739
    Abstract: A method of correcting vision by a vision correcting apparatus including a focus adjustable lens, includes: determining a first dioptric power to match far focus, based on far vision of a user; determining a second dioptric power to match near focus, based on corrected near vision of the user measured based on the first dioptric power; determining at least one third dioptric power to be applied to the focus adjustable lens, based on the first dioptric power and the second dioptric power; and controlling the focus adjustable lens based on the at least one third dioptric power.

  • Publication number: 20230036308
    Abstract: Provided are an apparatus and method for measuring a visual acuity (VA) by using a focus-tunable lens. The apparatus includes a display engine, an image combiner, a focus-tunable lens provided on a path of the light guided by the image combiner, an input device, and a processor configured to control the focus-tunable lens to assign different first and second optical powers to first and second lens regions, respectively, on a lens surface of the focus-tunable lens, control the display engine to display a VA measuring image through first and second output regions of the image combiner, control the input device to receive a user's input with respect to the VA measuring image, specify one optical power of the first and second optical powers based on the user's input, and determine a VA of a user based on the specified optical power.

  • Publication number: 20220269342
    Abstract: Provided is an electronic device for detecting lost portions of a field of vision and distorted portions of a field of vision and storing these in a vision map. The lost portions and distorted portions are identified in cooperation with the user by means of virtual image superposition on a real scene, audible requests to the user, gesture inputs provided by the user and gaze tracking. The electronic device may detect an object and provide visual information to a user when the object is in a lost portion or distorted portion of the field of vision.

  • Patent number: 10459128
    Abstract: A liquid crystal device (100) for focusing visible light, the liquid crystal device (100) comprising a plurality of curved substrates (101,102) arranged to form one or more curved cavities (104) therebetween, each substrate being configured to provide a focal power, wherein the one or more curved cavities contain liquid crystal and form one or more liquid crystal elements. Each of the one or more liquid crystal elements are configured to provide a focal power, the focal power of each of the liquid crystal elements being dependent on the curvature of the respective cavity and a voltage applied across the liquid crystal contained within the respective cavity. The substrates (101,102) in combination with the one or more liquid crystal elements are arranged to provide a first focal power in a substantial absence of an applied voltage and a second focal power in response to an applied voltage.
