Twenty airline pilots measured their near point of accommodation employing a modified Princes' Rule. Measurements were performed periodically travelling east- and west-bound. Five clerical control subjects performed the same measurements over 2 consecutive days. The ranges of variability of the nearpoint of accommodation were compared between the two groups, directions and days. No statistically significant differences in the variability of accommodation were found in the comparisons.
20名航空公司飞行员采用改良的普林斯法则测量了他们的调节近点。测量在定期往返东西方的行程中进行。5名文书对照组受试者在连续两天内进行了相同的测量。对两组之间、不同方向和不同日期的调节近点变异性范围进行了比较。在这些比较中，未发现调节变异性存在统计学上的显著差异。
