Spatiotopic cues, such as perceived distance, have little effect on accommodation unless blur has been reduced or eliminated. We investigated the effect of perceived distance on accommodation under binocular steady-state conditions, about which little is known. Blur was reduced but not eliminated by using a stimulus with a moderately low luminance. Accommodation was measured under two conditions: (1) when cues from perceived distance, blur, and convergence were aligned; and (2) when perceived distance was opposed by both blur and convergence. We found a significant difference in accommodation between the two conditions, which we attribute to perceived distance.
空间位置线索，如感知到的距离，对调节的影响很小，除非模糊已经减轻或消除。我们研究了在双眼稳态条件下感知距离对调节的影响，对此了解甚少。通过使用适度低亮度的刺激来减少但不消除模糊。在两种条件下测量调节：(1) 当来自感知距离、模糊和集合的线索一致时；(2) 当感知距离与模糊和集合都相反时。我们发现两种条件下的调节存在显著差异，我们将其归因于感知距离。
