NEAR FOCUS CORRECTIVE AR GLASSES

Abstract:

A head-mounted display for an augmented reality application includes an image light guide arranged within the aperture of an eye rim section of the head-mounted display for directing angularly related image-bearing light beams encoding a virtual object toward an eyebox for the viewing the virtual object at a hyperfocal to near infinite focusing distance to the eyebox. A negative-power optic between one side of the image light guide and the eyebox diverges the image-bearing beams in advance of the eyebox for viewing the virtual object at a closer distance to the eyebox that is less than the hyperfocal distance. A positive-power optic on an opposite side of the image light guide compensates for the negative-power of the negative-power optic for viewing a real-world object at its actual distance to the eyebox. A corrective optic located between the image light guide and the eyebox reduces the viewer's aberrations for viewing of both the real-world object and the virtual object.
