Objective Adjusting the eye tracker and applying it in objectively measuring of the eye horizontal movement. Evaluating the accuracy of it in measuring the vergence.Methods Properly set and adjusted, the eye tracker was used to record the horizontal eye movement, then analyze the data by correlative software.Results The instrument was able to record the horizontal eye movement accurately and objectively. The dynamic process of eye movement during fixation and saccade can be record easily. The instrument made it easy to count the motor-ocular parameters such as vergence and response AC/A.Conclusion The eye tracker can be used to measure the eye movement accurately and easily. It was of practical value to measure ocularmotor parameter and it'll be expansively applied in the accommodation and vergence research field.
