Abstract: FIELD: medical equipment.SUBSTANCE: product configured to measure the interpupillary distance between the pupils of the user comprises one or more material computer-readable non-recurrent data media, containing computer-executable instructions, made with possibility, at their execution by at least one computer processor, to perform execution of at least one computer processor stages, including processing information on image captured by sensor of device for image capturing, for determining, based on image information of the identified locations of the first and second light reflections of the light source, wherein identification of the first and second reflections locations comprises identifying the first reflection location by identifying the first Purkinje image light reflection light source from the outer reflecting surface of the user's first eye cornea, and identifying the second reflection location by identifying the first Purkinje image light reflection light source from the outer reflecting surface of the second user eye cornea, determination of estimated distance, which is distance between sensor and pupils of user, when image information is captured by sensor, and determining interpupillary distance based on estimated distance and identified locations of said first and second reflections. Mobile device configured to measure the interpupillary distance between the pupils of the user comprises a light source configured to generate light to illuminate the pupils of the user, device for capturing an image, comprising a sensor configured to capture information on an image corresponding to the pupils of the user, and a processor, configured to identify, based on the image information of the first and second light reflections of the light source of the mobile device, wherein the processor is configured to identify the first reflection location by identifying a first Purkinje image light reflection light source from the outer reflective surface of the cornea of the first eye of the user, and identifying the second reflection location by identifying the first Purkinje image light reflection light source from the external reflecting surface of the second user eye cornea, wherein the processor is configured to determine the estimated distance, which is the distance between the sensor and the pupils of the user, when the image information is captured by the sensor, and with possibility of detecting interpupillary distance based on estimated distance and identified locations of said first and second reflections. Method for measuring interpupillary distance between pupils of a user involves processing information on an image captured by a sensor of a device for capturing an image, for determining, based on image information of the identified locations of the first and second light reflections of the light source, wherein identification of the first and second reflections locations comprises identifying the first reflection location by identifying the first Purkinje image light reflection light source from the outer reflecting surface of the user's first eye cornea, and identifying the second reflection location by identifying the first Purkinje image light reflection light source from the outer reflecting surface of the second user eye cornea, determining the estimated distance, which is the distance between the sensor and the pupils of the user, when the image information is captured by the sensor, and determining interpupillary distance based on estimated distance and identified locations of said first and second reflections. A computing device configured to measure an interpupillary distance between pupils of a user and comprising at least one processor configured to perform a method according to any of claims 27–39.EFFECT: technical result of the proposed invention consists in increase in the accuracy of detecting an interpupillary distance.40 cl, 11 dwg
