Fig. 6From: The biomechanical significance of pulley on binocular visionComparison of binocular visions between two different interocular distances b0 and b1. The fixation points P0 and P1 denote two different objects; b0 and b1 are the corresponding interocular distances, and b0 > b1; L0 and L1 are the corresponding distances from the object points P0 and P1 to the eye, respectively; angle θ is the corresponding binocular subtense angle of the object, and θ = b0/L0 Back to article page
