Embodiment Construction

[0042]The invention relates to a system, for example an eyewear equipment, for generating a virtual image of a wearer.

[0043]In the reminder of the description, terms like «up», «bottom», «horizontal», «vertical», «above», «below», «front», «rear» or other words indicating relative position may be used. These terms are to be understood in the wearing conditions of the system or eyewear equipment of the invention.

[0044]As illustrated on FIG. 1, the invention relates to system 10 for generating a virtual image for a wearer. Preferably, the system 10 of the invention is part of an eyewear equipment intended to be worn by a wearer.

[0045]The system according to the invention comprises at least:

[0046]a lens 12,

[0047]a directive light source 14a, 14b,

[0048]a reflecting element 16,

[0049]a dynamical optical element 18, and

[0050]a memory 20 storing prescription data relative to the prescription of the wearer.

[0051]The lens 12 provides vision of real scene to the wearer and has refractive power r

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.
