一个远程haploscopic视频验光仪被用来评估一组32正视，正眼，无症状，年轻的成年人天真的视觉实验在最低限度的指示设置的聚散和调节反应。图像目标呈现在2m和33cm之间的四个位置。模糊，差距和迫在眉睫的线索，提出了组合或单独评估其贡献的总近反应在一个内的主题设计。反应增益的聚散和调节显着降低时，差距被排除在外，与小得多的影响时，模糊和接近被排除在外。尽管参与者组的临床同质性也有一些个体差异。
A remote haploscopic video refractor was used to assess vergence and accommodation responses in a group of 32 emmetropic, orthophoric, symptom free, young adults naïve to vision experiments in a minimally instructed setting. Picture targets were presented at four positions between 2m and 33cm. Blur, disparity and looming cues were presented in combination or separately to asses their contributions to the total near response in a within-subjects design. Response gain for both vergence and accommodation reduced markedly whenever disparity was excluded, with much smaller effects when blur and proximity were excluded. Despite the clinical homogeneity of the participant group there were also some individual differences.
