An oculography method, in particular a smart-glasses oculography method for pairs of augmented reality smart glasses and / or for pairs of virtual reality (VR) smart glasses / VR headsets. The method includes at least one oculography step in which at least one eye movement of an eye, in particular an eye of a smart-glasses user, is ascertained, in particular tracked, by a subset of laser feedback interferometry sensors of an LFI sensor array which is associated with the eye. In at least one selection step, which precedes the oculography step in time, a selection of at least one LFI sensor provided for performing the oculography step, which follows in time, is made based on a parameter comparison of test measurements of multiple LFI Sensors of the LFI sensor array.

The present disclosure relates to optical films for spectacle lenses for use with eyes experiencing eye-length-related disorders, like myopia. The optical films are configured with a plurality of optical elements, such as a plus-powered donut-ring and optical elements with azimuthally varying power distributions configured with truncations, depressions or a tilt. The arrangement, power, size, number and / or orientation of the optical elements are pseudo-random. This configuration provides dynamic irregular directional cues to the eye which occur during natural and / or instructed eye movements. Instructions on eye movements may be provided via a Myopia Management App. This invention is aimed at slowing the progression of myopia or at preventing or slowing the onset of myopia.

The invention relates to a method for providing control data for an ophthalmic ablation laser (12) of a treatment device (10). The method comprises determining a laser pulse positioning inaccuracy based on a predetermined statistic of eye movements and a predetermined processing latency, wherein the processing latency comprises a latency of a camera device (24), a beam deflection device (22), and the ablation laser (12); determining an ablation volume (14) for correcting a refractive error as a function of the determined laser pulse positioning inaccuracy; and providing the control data for controlling the ablation laser (12), which includes the determined ablation volume (14).

Introduced here are approaches to generating an image with a fundus camera based on parameters determined through modeling of eye motion. The method captures a series of images to generate pupil position data over time. Using this data, the method determines a model for estimating pupil positions and predicts a time associated with a minimum pupil velocity. The method can estimate the pupil position at this time and generate a fundus camera configuration based on the position. The method can transmit a command to capture an image of the eye using the fundus camera configuration. By implementing these approaches, an imaging system can improve the quality of retinal imaging for patients with eye motion.

The application discloses a glasses leg structure type electroencephalogram collection electrode and intelligent electroencephalogram collection glasses, and belongs to the technical field of brain-computer interfaces. The electrode comprises a recording electrode integrated in the inner side of a glasses leg, a reference electrode integrated in a nose pad and a signal transmission circuit. The recording electrode is attached to the head to collect electroencephalogram signals, the reference electrode provides a reference potential, and the signal transmission circuit is connected to a signal processing module. The intelligent electroencephalogram collection glasses further comprise a glasses frame, a power module and an optional eye movement tracking module. The glasses can fuse electroencephalogram signals and eye movement signals, and output control instructions after feature extraction, customized combination and intention recognition. The electrode and the glasses are designed in an integrated manner, and the wearing comfort and signal collection stability are considered, so that the non-invasive and convenient collection of electroencephalogram signals is realized, and the glasses are suitable for daily use.
