Abstract: A near eye display includes a main freeform prism lens and a micro-display corrector lens, where the main freeform prism lens includes a first freeform surface, a second freeform surface, and a third freeform surface, the first freeform surface refracting a light from a micro-display into a body of the main freeform prism lens, and the main freeform prism lens having an exit pupil diameter greater than 12 millimeter (mm), and a lateral color aberration of less than 4 micrometer (um)) across a diagonal field of view (FOV), where the micro-display corrector lens is positioned between the main freeform prism lens and the micro-display, the micro-display corrector lens including a first corrector lens surface and a second corrector lens surface, and each surface of the main freeform prism lens and the micro-display corrector lens comprises a surface sag.
