Abstract: An optical device includes a display that emits light toward a lightguide. Display light reflects from lightguide surfaces by total internal reflection (TIR). The display is mounted proximate to the lightguide. The optical device includes a first surface at an eye-side of the optical device and a second surface at a world-side. The optical device includes a first material having a first Abbe number and a second material having a second Abbe number different from the first Abbe number. The first material and the second material cause a color correction to light from the display or alters a chromatic aberration of the light from the display. A head mountable frame supports the display and the lightguide including the first and second materials.

Abstract: An optical device includes a display that emits light through a polarization grating and then through a field lens toward a lightguide. Display light reflects from lightguide surfaces by total internal reflection (TIR). The display is mounted proximate to the lightguide. The optical device includes a first surface at an eye-side of the optical device and a second surface at a world-side. The optical device includes a first material having a first Abbe number and a second material having a second Abbe number different from the first Abbe number. The polarization grating, the first material, and the second material cause a color correction to light from the display or alter a chromatic aberration of the light from the display. A head mountable frame supports the display and the lightguide including the first and second materials.
