1. A display device to be worn on a head of a wearer comprising:
- an image formation device;
an off-axis reflective combiner; and
imaging optics disposed in an optical path between the image formation device and the off-axis reflective combiner, wherein said imaging optics comprises no more than two lenses and no reflectors having optical powerwherein said no more than two lenses comprise two lenses, a first and a second, and said two lenses are the only lenses in said optical path between the image formation device and the off-axis reflective combiner, said first lens having a first surface and a second surface, said first and second surfaces not having optical axes that are collinear such that said first lens is non-rotationally symmetric.

Abstract
One embodiment of the invention comprises a simplified light-weight head mounted displays comprising an off-axis combiner and a pair of plastic lenses. One of the lenses is a rotationally symmetric optical element and one of the lens is a non-rotationally symmetric optical element. This non-rotationally symmetric optical element comprises first and second lens surfaces that are tilted and decentered with respect to each other. One of these first and second lens surfaces may also include diffractive feature to provide a diffractive or holographic optical element for color correction.
