Monocular and binocular abutting line vernier acuities were measured as a function of contrast. Over a range of contrasts from near the line-detection threshold to approximately 20 times threshold, binocular vernier thresholds are lower (better) than monocular thresholds by approximately 50-60%, similar to the binocular improvement found for the detection of both a thin line and a dipole. At higher contrasts the binocular advantage diminishes, apparently as a result of saturation.
测量了单眼和双眼邻接线游标视力作为对比度的函数。在从接近线条检测阈值到大约阈值20倍的一系列对比度范围内，双眼游标阈值比单眼阈值低（更好）约50 - 60%，这与检测细线和偶极子时发现的双眼改善情况相似。在更高的对比度下，双眼优势减弱，显然是饱和的结果。
