Abstract

An information system and a method for providing information in correlation with light that is incident on an eye includes a holographic element disposed in front of the eye and a device capable of recording optical signals which detects light that is incident on the eye via the holographic element. The device capable of recording optical signals detects light which is diffracted by the holographic element before the light impinges on the eye such that the diffracted light does not enter the eye.
