An optical system for aberration compensation comprising an optical module and an asymmetric refractive index distribution film is disclosed. The asymmetric refractive index distribution film comprises a liquid crystal and a liquid crystalline polymer, wherein the asymmetric refractive index distribution film set on an out-light surface or an in-light surface of the optical module. A display system comprising the above-mentioned optical system and an image panel are also disclosed herein. The asymmetric refractive index distribution film of the present invention has non-uniform refractive index distribution so as to effectively compensate the aberration formed by the optical module.

A head-mounted display (HMD) apparatus includes an HMD device and a liquid crystal (LC) lens device. The HMD device has a light entering surface for entrance of ambient light, and a light exit surface. The HMD device permits passage of the ambient light therethrough to form a real world image for an observer who wears the HMD apparatus, and generates and projects display light toward the light exit surface to form a computer-generated image for the observer. The LC lens device has an adjustable focal length and is disposed to change convergence of the ambient light and the display light from the HMD device, so as to correct vision of the observer.
