Annotation
Two patented methods of dynamic visual acuity (DVA) evaluating are described. Method 1 found on using the device that contain a rotating cylinder with a optotype table (strings of black squares separated by white stripes) on the outer surface. Method 2 found on using of high-speed video recording of patient eye movements during recognition of moving optotype (Landolt ring demonstrated on the screen). Statistics on the DVA values measured in a group of subjects in the age 21—35 years was collected (number of participants: method 1—42, method 2—9). The mean DVA value obtained from measurements by the method 1 equals to 25.08 ms, and measurements by the method 2 give 272 ms. Results of performed measurements are presented in various systems of units.
