Abstract: A process is provided for conducting an eye examination using a mobile device, the process comprising capturing a first image of an object using a camera of a mobile device set to a fixed focusing distance; determining, with reference to the first image, an absolute size of the object; capturing a second image of the object using the camera of the mobile device; determining, with reference to the second image, a distance from the mobile device to the object; providing an indication via the mobile device to move the mobile device relative to the object; and receiving input from the mobile device in response to the eye examination program.

Abstract: A process is provided for determining characteristics of a lens, the process including obtaining a captured image of a pattern through a corrective lens; transforming the captured image to an ideal coordinate system; processing the captured image to determine an overall distortion from a reference pattern to the pattern of the captured image; determining a distortion of the captured pattern attributable to the corrective lens; and measuring at least one characteristic of the corrective lens. In some embodiments, the overall distortion is determined by detecting, in the captured image, at least one captured pattern landmark; determining a transformation from at least one ideal pattern landmark to the at least one captured pattern landmark; and determining for the corrective lens, from the transformation, a spherical power measurement, a cylinder power measurement, and an astigmatism angle measurement.

Abstract: A system having at least one processor and at least one memory for predicting a fit quality between a wearable device and one or more customers is disclosed. The system comprises: a user interface generator configured for receiving a request from a user; a population engine configured for generating, based on the request, simulated head data based on real head data of a sample of customers; and a fit engine configured for determining fit information between the simulated head data and at least one design of the wearable device, wherein the fit information is displayed to the user as a response to the request. Methods and uses thereof are also disclosed.

Abstract: Various aspects of the subject technology relate to systems, methods, and machine-readable media for virtual fitting of items such as spectacles and/or spectacle frames. A user interface for virtual fitting may be implemented at a server or at a user device, and utilize three-dimensional information for the user and three-dimensional information for each frame, with frame information stored in a frame database, to identify and/or recommend frames that are likely to fit the user. Fit information can be provided for a group of frames or for each individual frame selected by the user. The fit information can be provided with a static image of the frames and/or within a virtual try-on operation in which the frames are virtually placed on a real-time image of the user.

Abstract: A lensmeter system may include a mobile device having a camera. The camera may capture a first image of a pattern through a lens that is separate from the camera, while the lens is in contact with a pattern. The mobile device may determine the size of the lens based on the first image and known features of the pattern. The camera may capture a second image of the pattern, while the lens is at an intermediate location between the camera and the pattern. The second image may be transformed to an ideal coordinate system, and processed determine a distortion of the pattern attributable to the lens. The mobile device may measure characteristics of the lens based on the distortion. Characteristics of the lens may include a spherical power, a cylinder power, and/or an astigmatism angle.
