Suppression of anisometropic blur induced by monovision contact lenses was examined in 18 presbyopic subjects. Suppression ability was quantified by reducing the contrast of a bright test target, viewed by subjects wearing a monovision correction, until the blurred image was suppressed. Subjective success with monovision was evaluated using a patient survey and no correlation to blur suppression ability was found. Objective success was evaluated in terms of performance at three near work tasks, each requiring a different level of stereoscopic localization. A significant correlation was found between card filing performance (requiring a moderate level of stereopsis) and blur suppression ability. Correcting either the dominant or non-dominant eye for near in the monovision correction did not significantly affect blur suppression ability. There was no evidence for adaptation to monovision in terms of increasing blur suppression ability over time.
在18名老花眼受试者中研究了单眼视力隐形眼镜引起的屈光参差性模糊的抑制情况。通过降低佩戴单眼视力矫正的受试者所观察到的明亮测试目标的对比度来量化抑制能力，直到模糊图像被抑制。使用患者调查问卷评估单眼视力的主观成功率，未发现与模糊抑制能力相关。根据三项近距工作任务的表现评估客观成功率，每项任务都需要不同程度的立体定位。发现卡片归档任务表现（需要中等程度的立体视觉）与模糊抑制能力之间存在显著相关性。在单眼视力矫正中，矫正主视眼或非主视眼用于近距视力，对模糊抑制能力没有显著影响。没有证据表明随着时间推移模糊抑制能力增加而出现对单眼视力的适应。
