摘要将单目视觉佩戴者的双眼焦深与单眼确定的两个焦深之和进行了比较。根据视力优势，观察者分为三组。在没有首选注视眼的受试者中，观察到单眼焦点深度的完全双眼总和。喜欢用一只眼睛注视的受试者很难抑制那只眼睛的模糊，而双眼目标则在非首选眼睛的焦深范围内。第三组显示了两个单眼焦点深度的部分总和。用SRI验光仪客观测量的调节反应模式，在配戴单视矫正的受试者中也观察到了类似的模式。对模糊中的正弦变化的调节反应主要由优势视力眼控制。这些结果证明了单视矫正中眼间抑制屈光参差模糊的有效性以及眼优势对这一抑制过程的影响。
ABSTRACT The binocular depth of focus of monovision wearers was compared to the sum of the two monocularly determined depths of focus. Observers fell into three groups based upon ocular sighting dominance. Complete binocular summation of the monocular depths of focus was observed in subjects without a preferred fixating eye. Subjects who preferred to fixate with one eye had difficulty suppressing blur of that eye while the binocular target was within the depth of focus of the nonpreferred eye. A third group showed partial summation of the two monocular depths of focus. Similar patterns of accommodative response, measured objectively with the SRI optometer, were observed in subjects wearing monovision corrections. Accommodative response to sinusoidal variations in blur was controlled primarily by the dominant sighting eye. These results demonstrate the effectiveness of interocular suppression of anisometropic blur in monovision correction and the influence of ocular dominance upon this suppression process.
