    摘要： Disclosed herein are a user device, server, and computer program for determining vision information. The computer program is stored in a computer-readable storage medium including encoded instructions. When executed by one or more processors of a computer system, the computer program causes the one or more processors to perform operations, the operations comprising the operations of: allowing the operation of a lighting unit to be controlled in response to a photographing request; allowing a photographing unit to acquire an image of a pupil of a user in response to the photographing request; allowing intensity profile information regarding the diameter of the pupil to be acquired from the image of the pupil; allowing crescent length information to be determined from the intensity profile information; and allowing the vision information of the user to be determined at least partially based on the crescent length information.

    摘要： The present disclosure generally relates to a technique for centering an application field for an ophthalmic device or a method. More specifically, and without limitation, the disclosure relates to a device and a method for centering an application field relative to the cornea of a human eye responsive to movement of the eye tracked in real-time during the ophthalmic application based on a pupil center. An ophthalmic device or method allows performing one or more procedures with respect to an eye of a patient, such as a surgical, therapeutic and diagnostic procedure, e.g., including and not limited to Laser-Assisted in-situ Keratomileusis (LASIK), Epi-LASIK, PRK, lenticule extraction or keratoplasty.

    摘要： There is provided a small-sized head-mount type vision testing device, which is a head-mount type vision testing device mounted on a testee's head, including: a display device that presents a visual target to an eyeball of the testee; a display optical system that guides a light of the visual target presented on the display device, to a retina of the eyeball; an imaging device that images the eyeball; and an observation optical system that guides an image of the eyeball to the imaging device, the display optical system further comprising a mirror that reflects a light of a specific wavelength and transmits the other light at a point closer to the eyeball side than the display device, wherein an optical axis from a pupil of the eyeball to the mirror in the display optical system and an optical axis from the pupil to the mirror in the observation optical system, coincide with each other, and the optical axis from the pupil of the eyeball to the mirror in the display optical system and an optical axis from the mirror to the display device in the display optical system, are bent through the mirror.

    摘要： According to an aspect of the present inventive concept there is provided a method for eye tracking, comprising: capturing (502) a sequence of digital images of an eye of a user; outputting (504) data including said sequence of images to an image processing unit (120); processing (506) said data by the image processing unit to determine a sequence of positions of the eye, each position being indicative of a gaze direction, acquiring (508) biosignal data representing an activity of the eye; and in response to detecting closing of the eye based on the acquired biosignal data, pausing (512) at least one of said capturing (502), said outputting (504) and said processing (506). A system (100) for implementing the method is also disclosed.
