1. A contact lens for augmented reality comprising:
a transparent body designed to be placed on an eye;
at least one augmented reality module comprising:
an optical source attached to the transparent body and designed to emit a light into the transparent body;
an optical element attached to the transparent body and designed to receive the light from the optical source and send it in the direction of the eye;
characterised in that the optical source is adapted to emit light, received by the optical element, comprising no image and in that the optical element is a hologram designed to diffract the received light so as to create a holographic image in the direction of the eye;
the contact lens further having a central area consisting solely of the transparent body.
