Abstract
An optical lens assembly for a near-eye display device includes a light box and a diffractive optical element (DOE). The light box has a first layer facing a display screen of the near-eye display device and a second layer facing the DOE. The light box is configured to receive a first light from a display screen of the near-eye display device and transmit at least a portion of the first light to the DOE through a folded optical path, where the first layer and the second layer are flat. The DOE aligned with an optical axis of an eye and is configured to receive a second light from the light box and converge the second light to the eye.
