Vision Disparity Clinical Trial
Official title:
Are There Different Objective Fixation Disparity Values for Two Different Test Paradigms: Similar to Reading Dot Presentation and Text Reading? - How This Phenomenon Can be Explained
In optometry, binocular coordination is measured subjectively. The result is subjective fixation disparity. In research different experiments have proven, that subjective and objective fixation disparity are different. A binocular eyetracker has to be calibrated. There are two well known calibration methods: associated and dissociated calibration. Objective fixation disparity is measured in arcMin. Therefore, the precision of the eyetracker plays a crucial role. Now, the investigators try to compare dissociated calibration with polarized filters and associated calibration under different test paradigms.
