1. A head-mounted display apparatus comprising:
- a head-mounted display device that has a light entering surface for entrance of ambient light, and a light exit surface, said head-mounted display device being configured to permit passage of the ambient light therethrough to form a real world image for an observer who wears said head-mounted display apparatus, and to generate and project display light toward said light exit surface to form a computer-generated image for the observer;
a first liquid crystal lens device which has an adjustable first focal length and which is disposed to change convergence of the ambient light and the display light from said head-mounted display device, so as to correct vision of the observer; and
a polarizer-free attenuator disposed to attenuate intensity of the ambient light that enters said head-mounted display device.

Abstract
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.
