In this study, we investigated whether the objective depth-of-focus (DOF) is different from the subjective DOF and whether it correlates to accommodative microfluctuations (AMF). The objective DOF and subjective DOF at 1.5 D accommodative stimulus (AS) level were compared in the same group of subjects. The objective DOF and magnitude of AMF were measured at 5 AS levels from 0 D to 4 D. Results showed that there was a significant difference and no correlation between the objective DOF and the subjective DOF. The objective DOF was correlated to the magnitude of AMF. The results suggest that objective DOF and subjective DOF represent the blur sensitivity of two different systems. AMF are correlated with the blur sensitivity of the accommodative system.
在本研究中，我们调查了客观焦深（DOF）是否与主观DOF不同，以及它是否与调节性微波动（AMF）相关。在同一组受试者中比较了1.5D调节刺激（AS）水平下的客观DOF和主观DOF。在从0D到4D的5个AS水平上测量了客观DOF和AMF的大小。结果表明，客观DOF与主观DOF之间存在显著差异且无相关性。客观DOF与AMF的大小相关。结果表明，客观DOF和主观DOF代表了两个不同系统的模糊敏感度。AMF与调节系统的模糊敏感度相关。
