(A) Rod-and-frame computer program on a computer monitor display. This system was used in complete darkness. (B) Subject wearing the Olympus Eye-Trek FMD 200 video eyeglasses. (C) Plot of the mean rod angles ± SEM (n=16) measured at different frame angles with subjects viewing the display on the computer monitor screen and through the video glasses. The significance of the differences from the means obtained with the frame set to 0° was determined using repeated-measures analysis of variance and the Dunnett multiple comparison test (*P<.05; **P<.01). The diagrams under the chart show the appearance of the display with the different frame angles.
