AIM:For rapid and exact examination of visual acuity, a computer-assisted automated vision testing system was designed. The examination results were compared with that of traditional visual charts to evaluate the possibility of clinical application of this system. METHODS:The vision testing software was designed and installed in the computer, the visual charts was displayed on the liquid crystal display (LCD). The directions of optotypes were inputted into computer by patients using wireless keyboard and examination results were displayed on screen and printed. Then the results by using this system were compared to that of traditional visual charts. The difference of the two examination methods was analyzed. RESULTS:This system is rapid and exact. The examination results by using this software can be repeated. The results by using this system have no difference compared to that of traditional visual charts. CONCLUSION:This system can be effectively used in clinic and also in school physical examination, especially in large scale visual acuity testing demands.
