A computer-implemented method, a computer program, and a device for determining a visual performance of an eye of a person are disclosed. The method includes displaying to at least one eye of a person a visual stimulus configured to elicit at least one type of eye movement in the at least one eye of the person with at least one screen; tracking the at least one type of eye movements in the at least one eye of the person with at least one eye tracker; determining the visual performance of the at least one eye of the person by using at least one first piece of information about the at least one visual stimulus and at least one second piece of information about an occurrence of the at least one type of eye movements in the at least one eye of the person with at least one processing unit.

Method and device for determining a visual performance

A computer-implemented method, a computer program, an apparatus, and a remote apparatus for determining at least one visual performance of at least one eye of a person for a plurality of points in a visual field of the person from tracking data by using at least the first spatial location of at least one visual fixation mark and the second spatial location of at least one visual stimulus are disclosed. An attention level of the person is determined by evaluating a time-related difference in reaction times between at least one particular measurement cycle and at least one subsequent measurement cycle. The automated visual performance test can be performed by any person irrespective of being an ophthalmologist or optometry specialist or not, particularly by using a mobile device.

Determining a visual performance of an eye of a person

A method, a device, and a computer program for determining at least one optical parameter of a spectacle lens, and a method for manufacturing the spectacle lens using the at least one optical parameter are disclosed. The optical parameter denotes a value for a property of the spectacle lens which is adjusted during manufacture of the spectacle lens to achieve an intended correction of ametropia of at least one eye of a user of the spectacle lens. The method includes: a) capturing at least one image of a user wearing the spectacle lens; and b) determining at least one optical parameter of the spectacle lens by image processing the at least one image, wherein the at least one image contains an eye portion including at least one eye and/or a face portion adjacent to at least one eye of a user of the spectacle lens.
