Recently, dynamic vision measurement and improvement in the virtual environment on the display and the monitor become widely known for the public. It is possible to measure and train easily in the virtual environment. However, the situation that a target moves discretely in the virtual environment and the situation that a target moves continuously in the real environment have a difference in vision. In this paper, we examine a difference of target's vision both in a virtual environment and in a real environment, and developed DVA measuring instrument that can measure similarly condition in both environments. The dynamic vision for various ages is measured, and we evaluate the correlation in the both environments.
