    Abstract: The present invention relates to a computer-implemented method (210), a computer program and a device (110) for determining a visual performance of at least one eye (112) of a person (114) as well as a method for producing at least one spectacle lens (228). Herein, the method (210) comprises the following steps: a) identifying (212) a point in time indicating that a person (114) is able to perceive at least one visual target (128) from a reaction of the person (114); b) determining (216) a visual performance (218) of at least one eye (112) of the person (114) by using at least one first piece of information about the at least one visual target (128) and at least one second piece of information about at least one parameter (168) related to the at least one visual target (128) at the point in time, c) recognizing (214) the at least one visual target (128) and the at least one parameter (168) related to the at least one visual target (128) at the point in time by scanning a natural environment (122) of the person (114).

    Abstract: This method for obtaining information related to a purported evolution of a visual field of an individual that may be a forerunner of an eye disease comprises: providing (10) a plurality of values of at least one parameter related to head movements, representing a reference head movement behavior; measuring (12) a same at least one parameter related to head movements of the individual in daily life, during a predetermined measurement period; comparing (14) the individual's head movement behavior with the reference head movement behavior; in case of detecting (16) a difference between both head movement behaviors, checking (18) whether there is any specific reason in the individual's daily life explaining that difference and, if there is no specific reason, obtaining (20), on the basis of that difference, information related to a purported evolution of the visual field that may be a forerunner of an eye disease.

    SYSTEMS AND METHODS FOR VISUAL FIELD TESTING IN HEAD-MOUNTED DISPLAYS

    Abstract: Some systems and methods disclosed herein facilitate calibration of a head-mounted display while a visual test is performed. One mechanism of facilitating calibration involves detecting, as a visual test is being performed, that the user's eyes moved in the direction of a displayed stimulus but have not stopped at the point of where the stimulus is displayed, and instead stopped at a different point (e.g., a threshold distance away from the stimulus). Based on that detection, the system may determine that the user has seen the stimulus and that calibration of the sensors is needed. The system may then record that the user has seen the stimulus and perform sensor calibration before displaying the next stimulus.
