Abstract: An optical system, a display apparatus, and smart glasses are provided. The optical system includes a transflective element, a reflective element and a plurality of microstructures. The transflective element is configured to reflect collimated incident light to the reflective element. The reflective element is configured to reflect the collimated incident light back to a light incident surface of the transflective element, so as to adjust an angle at which the collimated incident light exits. The transflective element is further configured to transmit the reflected-back collimated incident light to a target region. The plurality of microstructures are configured to adjust angles at which ambient stray light incident on surfaces thereof exits, and to scatter the ambient stray light out of the target region.

Abstract: A near-to-eye display device, includes: a display screen configured to display different images in a first time division mode, a polarization converter at a light-emitting side of the display screen and configured to convert emitted light of the different images displayed by the display screen into first circularly polarized light rays and second circularly polarized light rays in a second time division mode. Here the first circularly polarized light rays and the second circularly polarized light rays are opposite in rotation direction. The device further includes a polarization lens at a side facing away from the display screen of the polarization converter, and a focusing lens at a side facing away from the display screen of the polarization converter. The polarization lens and the focusing lens are configured to focus the first circularly polarized light rays and the second circularly polarized light rays at positions of different focal lengths.
