Abstract
A system for generating a virtual image for a wearer includes: a lens providing vision of a real scene and having refractive power related to the prescription of the wearer, a directive light source that emits directive light beams to create the virtual image, a reflecting element positioned on or in the lens that receives and redirects the directive light beams emitted by the directive light source toward a convergence area of an eye of the wearer, a dynamical optical element for modifying the received light beams, and a memory storing prescription data relative to the prescription of the wearer, the dynamical optical element modifying the light beams at the convergence area so as to compensate at least partly the prescription of the wearer.
