For wearable device, the most importance point for image system is miniaturization. In this paper, we present a headmount display that reduces the distance between the eyeball to the lens and its thickness. In traditional, the thickness of head-mount display is not thin enough because of it is designed that the light source is transmit a series of lenses. It make a large volume of head-mounted display. The system consists of three curve mirrors and a free-form lens. Mirrors and lens can form a reflective design. The image source is placed be next to the eyeball. We expect the image to go through the mirrors to the eyeball so that make the volume of head-mount display can be thinner. The goal of system is 60 mm thick and 140 mm wide. The field of view is designed to be 140 degree. By using the 3D printer, we can make a model of glass to achieve our design.
