Abstract

The design of a visual optical system for eye and vision examination using video-based chart is investigated in this paper. It produced a virtual image larger than the original display and much farther away from the tester eye. The diagonal length of a virtual image is enlarged as the optical system is designed to match the resolution of human eye. The optical system provides a wide observing area. The optical system also has a large field of view. It has a comfortable long eye relief. The design results and image analysis are also discussed in this paper.
