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).

Abstract: A method—for printing a 3D object, defined by a 3D image having multiple illuminated points, in a photoreactive composition volume—includes extracting from the image a mosaic sequence. Each mosaic includes multiple solid areas, each including illuminated point(s). The mosaic sequence is projected in an axial direction, inside the volume, to form—from each projected mosaic—multiple light areas, each corresponding to a solid area of the projected mosaic. In the solid area of a mosaic, a number of illuminated points and the distribution of the illuminated points are adjusted so, when projecting the mosaic is into the volume, the light area corresponding to the solid area causes a photoreaction in an associated composition block with a desired axial resolution. In the same mosaic, the solid areas are distributed such that, when projecting the mosaic into the volume, the composition does not react between the light areas associated with the multiple solid areas.
