Abstract: Prescription profile information for corrective lenses used in conjunction with a near-eye display device is obtained by the near-eye display device to facilitate correction of aberrations introduced by the corrective lenses. The prescription profile information can be transmitted electronically to the near-eye display device, embedded on the lens surface of the corrective lens itself using a near invisible marking such as near-infrared ink that can be detected by a gaze-tracking camera of the near-eye display device, or the near-eye display device can infer the prescription profile information for the corrective lenses based on the locations of glints reflected by the corrective lenses and detected by the gaze-tracking camera. Based on the prescription profile information, the near-eye display device calibrates the display, sensors, and/or gaze-tracking circuitry to correct aberrations introduced by the corrective lenses.

Abstract: A system is disclosed for correcting a world-additive display of a head mounted device (HMD). The system includes a processor of a controller of the HMD connected to the world-additive display and a memory on which are stored machine-readable instructions that when executed by the processor, cause the processor to perform a process. The process includes receiving optical data from the world-additive display, receiving background data from an optical sensor connected to the controller, deriving scene estimate data from the background data, extracting display color estimate data from the optical data, generating a correction map based on the scene estimate data and the display color estimate data, and applying the correction map to the optical data. Corresponding methods and devices are also disclosed.

Abstract: The present invention relates to novel substrates, to methods of making them and to uses therefor. The substrates of the invention comprise a base portion and a surface layer covering at least part of the base portion, with a binding layer provided therebetween. The surface layer provides, on at least a part of the substrate, topographical features having at least one nano scale dimension. These topographical features are adapted to inhibit cell or tissue growth thereon and/or therebetween.
