Ocular vision system with optical guide that can be positioned in two positions

An ocular vision system intended to be worn by a user, said system comprising a display module, the display module comprising a transparent optical guide arranged to propagate, by total internal reflections, a light beam transporting an image as far as an extraction section of said optical guide, comprising:

• means for positioning the optical guide in a first position in which the extraction section is placed on a first axis corresponding to a nominal axis of sight (7.2) of the eye of the user;
• means for positioning the optical guide in a second position in which the extraction section is placed on a second axis offset with respect to the nominal axis of sight of the eye of the user;
• and
• means for rotating the optical guide adapted for enabling the optical guide to pass from the first position to the second position and vice versa;
• wherein the means for rotating the optical guide are arranged to perform the rotation about an axis intended to pass substantially through the centre of rotation of the eye of the user,
• and wherein, for rotating the optical guide between the first position and the second position, said system comprises:
• a stud holder comprising at least one stud;
• and
• a fixing and guiding support comprising at least one oblong groove arranged to receive said stud, each groove being such that, when said stud is placed at one end of said groove, the optical guide is in the first position and, when said stud is placed at the other end of said groove, the optical guide is in the second position.
