1. A head-mounted augmented reality stereo vision optical film, comprising:
a light-transmitting display layer, having a plurality of pixel units;
an optical projection layer, having a plurality of lens units, wherein one of the lens units is configured to correspond to at least one of the pixel units; and
an eyeball tracking layer, having a plurality of micro-sensing elements, wherein in a viewing direction of a wearer, the optical projection layer is located between the light-transmitting display layer and the eyeball tracking layer, and the eyeball tracking layer is located between the wearer and the optical projection layer,
wherein the micro-sensing elements are suitable for sensing an eyeball of the wearer;
wherein there is a first distance between the light-transmitting display layer and the optical projection layer, there is a second distance between the optical projection layer and the eyeball tracking layer, there is a viewing distance between the head-mounted augmented reality stereo vision optical film and the eyeball, and the viewing distance is greater than the first distance or the second distance.
