ABSTRACT:
An HMD device is provided, comprising an image element for generating an image and imaging optics projecting the image such that it is perceivable by a user wearing said HMD device, wherein said imaging optics comprise a first optical group including a first lens, which has negative refractive power, and a second lens, which has positive refractive power, a deflecting element arranged following the first optical group as well as a second optical group following the deflecting element, said second optical group comprising a third lens, and wherein, for correction of astigmatism and distortion, at least one surface of the first and second lenses is aspheric and, for correction of the spherical aberration, at least one surface of the third lens is aspheric.
