The Contrast Study Of Dominant Eye And Non-dominant Eye During Eye Movement

ObjectivesTo compare the eye movement between the dominant eye and non-dominant eye in the Chinese passages reading task and images searching task.MethodsExperiment A: Separately,Twenty people use the dominant eye or the non-dominant eye or binocular reading three paragraphs the same difficulty, then answer the questions; Experiment B: Separately, Twenty people use the dominant eye,the non-dominant eye and binocular each searching three images with the same difficulty, then answer the questions; The EyeLink.2000eye tracking system of Canada SR was applied to record the indexes of eye movement in this study.ResultsAnswer accuracy was94.7%during reading test procedure.There was no satistically significant difference between the dominant eye and the non-dominant eye.Answer accuracy was95%during searching image test procedure.There was no statistically significant difference between the dominant eye and the non-dominant eye for average searching time(P=0.210),for watching time(P=0.534),for total at times(P=0.880).Pupillary size for binocular watching was less than monocular watching in the images searching task,difference was statistically significant(P<0.001).Average watching time was not statistically significantly different between the binocular and the dominant eye,but less than non-dominant eye.The difference was statistically significant(P=0.026).Watching time for binocular was less than monocular in the image searching task,difference was statistically significant(P<0.01).Total at times for binocular was less than for monocular in the image searching task,difference was statistically significant(P<0.05). ConclusionThere were no statistically significant differences in the eye movement study procedure between dominant eye and non-dominant eye whether text reading or image searching when the distance from the eye to the target is91centimeters.Binocular working was more efficient than monocular working during the image searching procedure.
