摘要： The invention relates to a method for training a preferred retinal locus of fixation for a person having an eye with a field of vision comprising an area of partially diminished or entirely degenerated visual acuity. The method is characterized in the steps: a) determining an inefficient retinal region in said field of vision of said eye of said person and b) inducing a preferred retinal locus of fixation for a vision task outside said inefficient retinal region.
In addition the invention relates to a device for training a preferred retinal locus of fixation for a person having an eye with a field of vision comprising an area of partially diminished or entirely degenerated visual acuity. The device is characterized in an inducing arrangement for inducing a preferred retinal locus of fixation for a vision task outside an inefficient retinal region in said field of vision of said eye of said person.

摘要： The present invention relates to a computer-implemented method for operating an optometry device, comprising the following steps:
- generating a first data set, said first data set comprising information about a distance of a user of the optometry device to an object,
- tuning a tunable lens of the optometry device based on the distance of a user of the optometry device to the object based on the first data set.
The inventive computer-implemented method is characterized in that the first data set is generated by using a LiDAR sensor, said LiDAR sensor is measuring the distance of a user of the optometry device to the object by evaluating a scene represented by the first data set.

摘要： The present invention relates to a spectacle lens (110) for at least one eye (112) of a user (114), a method for producing a spectacle lens (110), and a computer program product comprising executable instructions for performing the method for producing the spectacle lens (110). The spectacle lens (110) comprises at least one permanent marking (120), wherein the at least one permanent marking (120) is or comprises at least one diffractive structure (124), wherein at least one diffractive pattern generated by illumination of the diffractive structure (124) is designated to be invisible upon a first kind of illumination (132) and designated to be visible only upon a second kind of illumination (144), wherein an incident light beam not comprising at least one wavelength in at least one of a near-infrared spectral region and a near-ultraviolet spectral region impinging on the lens body (116) outside the at least one diffractive pattern or on the least one diffractive pattern is transmitted without altering the spectral distribution of the light beam, whereas an incident light beam comprising at least one wavelength in at least one of a near-infrared spectral region and a near-ultraviolet spectral region which impinges on the least one diffractive pattern alters the spectral distribution of the light beam.
The permanent markings (120) on the spectacle lens (110) is, on one hand, invisible to the user (114) or to a spectator looking at the user (114) wearing the at least one spectacle lens (110) without utilizing specially selected optical aids but, on the other hand, enables continued control of the at least one spectacle lens (110) in front of the at least one eye (112) of the user (114) by an optician or a specifically designated optical sensor.

摘要： The present invention relates to a computer-implemented method (500) for determining at least one visual parameter of at least one eye (302) of a person (300), wherein an at least one first visual stimulus (200) and an at least one second visual stimulus (210) are displayed at the same time on the screen (102) effecting a resulting eye movement depending on the at least one visual parameter; wherein the at least one first visual stimulus or the at least one second visual stimulus (210) is a pursuit stimulus.
The present invention further relates to an apparatus (100) for determining a visual parameter of at least one eye (302) of a person (300).
Due to the displaying the at least one first visual stimulus (200) and the at least one second visual stimulus (210), particularly with at least one differing visual stimulus parameter, at the same time on the screen (102) the method (500) is more robust and more exact in determining the visual parameter compared to known methods wherein only one visual stimulus is being displayed.
