| Research Abstract |
1. INVESTIGATION OF ATTITUDE OF STUDENTS : WE INVESTIGATED THE ATTITUDE OF STUDENTS AT UNCONSCIOUSLY READING AND WRITING, AND AT CONCENTRATED VISUAL WORK.THE RESULTS OF THE INVESTIGATION WAS THAT THE VISUAL LINE DISTANCE OF WRITING WAS SHORTER THAN READING.AT CONCENTRATED VISUAL WORK, THE VISUAL LINE DISTANCE SMALLER THAN 20CM WAS ABOUT 65% ON THE WHOLE.THUS, IT IS SHOWED THAT THE VISUAL LINE DISTANCE HAVE A TENDENCY TO DECREASE AT THIS WORK.
2.VISUAL ACUITY UNDER ASTHENOPIA LOADING : FIRST, IN ORDER TO KEEP THE ATTITUDE CONSTANT UNDER ASTHENOPIA LOADING, WE DEVELOPED THE MEASUREMENT DEVICE OF VISUAL LINE DISTANCE.THIS DEVICE WAS IMPROVED ON THE ACCURACY AND THE TREATMENT.THIS ATTITUDE CONTROL METHOD WAS BASED ON BIOFEEDBACK.VISUAL ACUITY IS ESTIMATED WITH THE RATE OF CORRECT ANSWER BY PRESENTED LANDOLT RINGS.LOAD TIME OF ASTHENOPIA WAS 5 AND 10 MINUTES.AND IT WAS EXPERIMENTED BY CHANGING THE VISUAL LINE TO EACH OF A SHORT DISTANCE AND A LONG DISTANCE.TRACING A CERTAIN DOCUMENT OF ENGLISH BY PENCIL WAS USED AS ASTHENOPIA LOADING.THE RESULTS WAS THAT VISUAL ACUITY WAS MAINTAINED AT A LONG DISTANCE, BUT WAS A BAD TURN AT A SHORT DISTANCE.
