Abstract: The present invention relates to an optical device for generating a diffracted image on a support (S), said device comprising a diffractive optical element (5) arranged to diffract an optical beam, in order to generate a diffraction image. The device further comprises an optical power mirror (7.1; 7.2; 7.3; 7.4; 7.5), the mirror being placed with respect to the diffractive optical element so as to project the diffraction figure towards the support to obtain a magnified version of the diffracted image.

Abstract: The contact lens (100) for augmented reality comprises: a transparent body (102) designed to be placed on an eye (104); and at least one augmented reality module comprising an optical source (114) attached to the transparent body (102) and designed to emit a light into the transparent body, and an optical element (116) attached to the transparent body (102) and designed to receive the light from the optical source (114) and send it in the direction of the eye (104).
The optical element (116) is a hologram designed to diffract the received light as a holographic image in the direction of the eye (104).
