Development of vision examining system

Currently, at the time when traffic safety education and health diagnose were done, the visual acuity test is very important, at the same time, the cognitive function of vision also is made much account of more and more. If the driver knows own vision value and ability, he will do better to drive. But the present vision examining machine has two demerits. When the vision examining was done, if the number of persons is very large, it will cost more time. This is one question. The other question is that the present machine is too weighty to move easy. In our study, we had developed a new vision examining machine. Our machine has not those two questions; in addition, we also had added some new function to the machine.
