Further, I and II are up and III and V are down; and then in the order of I, II, III and IV, "inward", "outward", "outward" and "inward" for the right eye and "outward" "inward", "inward" and "outward" for the left eye are displayed. The fan-shaped rotary rule, rotatably pivoted on right-hand side point (0, 0) has a prism dioptric scale of 0W6Δ marked in an arc shape centering on point (0, 0). At the center and both sides of the fan shape, straight lines C1, C2 and C3 are provided.
