- Each spectacle lens 103, 15 can each have an image detector.
- the image detectors can be designed for image acquisition of the respective eye of the person, so that an authentication of the person on the basis of image acquisition of the left eye, the image acquisition of the right eye or the image of both eyes can be done.
- the authentication on the basis of the image recordings of both eyes can be particularly accurate and forgery-proof.
- a positive authentication of the person takes place, for example, only if the person can be authenticated on the basis of a biometric feature in the respective image recording of the left and the right eye. Furthermore, further biometric features of the person can be detected when taking pictures of both eyes.
- the processor 107 is formed, for example, in FIG.
- the processor 107 can then determine an eye distance or an iris distance of the two eyes.
- the eye relief or iris distance represents another biometric feature on the basis of which the processor 107 can authenticate the person.
- the eyewear authentication device 100 is known as
- Augmented reality glasses or virtual reality glasses are designed, or integrated into augmented reality glasses or virtual reality glasses.
- the image detector 105 can be arranged in a display, in particular in a partially transparent display, the augmented reality glasses or the virtual reality glasses.
