The eye direction appears to be upward in the upper-left image, downward in the upper-right one, leftward in the lower-left one, and rightward in the lower-right image. These images show apparent repulsion effects of eye direction against dark eye shadows.

"A brief image for the detection of visual field deficits: Method of reduction of the extinction illusion"

One gazes at the center with one eye, and blue dots appear to extinguish soon. When the observer approach or move away from the image slowly, blue dots appear to emerge again. If there is a part which lacks blue dots, the part might possibly be a deficit of the visual field. The blind spots are observed easily. This method is effective in the range within about 15-deg eccentricity, depending on the size of the display or print.
