Abstract:
Peripheral retinal sensitivities were measured for right and left eyes using a monocular night vision device NVD single tube ANAVS-6 Aviators Night Vision Imaging System in front of the right eye under simulated high and low night illuminations. Small circular targets were projected with a modified Goldman perimeter for six subjects. The color of the targets were white, green, and red. Targets were presented in the temporal field along the horizontal meridian at 10, 30, and 45 degrees to the unaided left eye, and at 30, 45, and 60 degrees for the NVD viewing eye. The results showed a decrease in sensitivity for the peripheral retina with the NVD and no effect on the nondisplay viewing eye, including the targets that were located within the projected field of view of the display eye 10-degree point. The nondisplay viewing eye left remained dark adapted to either the high or low night light level. Changes in the detection of green and white colored targets with peripheral vision by the display eye showed more effect in decreased retinal sensitivity than the red targets. However, the decreases in dark adaptation from viewing the display were similar to the differences in retinal sensitivity between the two simulated night illuminations for the nondisplay viewing eye.
