1. A device for improving the vision of an eye (1) of a human being, said eye pivoting in its orbit (2) and including a lens (7) and a retina (8), the device comprising:
optical means (10) for forming at least one image of a scene to be viewed (11); a controllable treatment optical projector (20) mounted to co-operate (13, 14) with said optical means (10), said projector being suitable for outputting (24) said image in the form of an image light beam (22), and for being controlled by a signal of determined value applied to a control input (21) so that the image light beam (22) is deflected through a deflection angle that is a function of the value of said signal; a mirror (30); means (40-1, 40-2) for linking said mirror (30) with the orbit (2) and with the treatment optical projector (20) so that the optical axis (31) of the mirror (30) passes substantially through the center of rotation (5) of said eye (1), and so that the mirror (30) lies on the light path of the image light beam (22); and a sensor (50) for determining the rotation of said eye (1) relative to its orbit (2), the sensor being suitable for outputting (51) a signal representative of the rotation; the device further comprising means (60) for applying said signal delivered at the output (51) of the sensor (50) to the input (21) of the treatment optical projector (20) so that the image light beam (22) is projected onto a location of said mirror (30) that is a function of the rotation of said eye (1) relative to its orbit (2). |
