The steady-state accommodation response to Snellen letters of different sizes was measured with a laser-Badal optometer. It was found that the accommodation response was least when viewing the 6/9 letter size for both monocular and binocular observation at 6 m and increased when the letter size got smaller or larger. The mean accommodation response for the monocular viewing state was significantly higher than the binocular state for Snellen letter sizes between 6/4.7 and 6/12. At 40 cm the accommodation response for different letter sizes showed no obvious trend. However, the lag in binocular accommodation was significantly less than the monocular lag.
使用激光巴德尔验光仪测量了对不同大小的斯内伦字母的稳态调节反应。结果发现，在6米处单眼和双眼观察时，观看6/9字母大小时调节反应最小，当字母大小变小或变大时调节反应增加。对于6/4.7至6/12之间的斯内伦字母大小，单眼观看状态下的平均调节反应显著高于双眼状态。在40厘米处，不同字母大小的调节反应没有明显趋势。然而，双眼调节滞后明显小于单眼滞后。
