Abstract
An optical unit (1) for augmented vision and augmented reality, which is to be placed in front of an eye of a user of the unit, includes a transparent or semitransparent screen (3), preferably a P-LED or TO-LED screen, and a unit (4) for collimating an image emitted by the screen toward the eye of the user, the collimating unit being a DOE, preferably an HOE, and the convergence function of the collimating unit being effective at a wavelength (FS) emitted by the screen.
