1. An information system for providing information in correlation with light incident on an eye, said system comprising:
- a holographic element disposed in front of the eye; and
a device capable of recording optical signals which detects light incident on the eye via the holographic element,wherein the device capable of recording optical signals detects light which is diffracted by the holographic element before the light impinges on the eye, and does not enter the eye.

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.
