Your distant vision is only 0. 2. Now come and have a look at this chart for the near vision. 您的远视力只有0.2,再查一下近视力,请看这张表。
If your trouble is with distant instead of near vision, use the same method with distant letters. 如果你的烦恼是远视力而不是近视力,就把这个方法用到远处的文字上。
Mr Obama's distant vision matters because nuclear weapons are once again at the very centre of global politics. 奥巴马这一远大愿景之所以事关重大,是因为核武器又一次成为国际政界最核心的话题。
Having one section that corrects for distant vision and another that corrects for near vision, as an eyeglass lens. The long-term clinical effects of binocular vision after LASIK in myopic anisometropia 双光的一个矫正远视而另一个矫正近视的,如眼镜手术矫治近视性屈光参差后双眼视觉的远期效果观察
The refractive state, aniseikonia, fusion, binocular image, near and distant stereoscopic vision and contrast sensitivity function were observed 1 month later after the operation. 对照组检测双眼屈光状态、影像不等、融合功能、远及近立体视功能以及对比敏感度功能。
[ Results] It was established that body high, distant vision, chromatic vision, blood pressure, audition should necessarily be examined, and those items influencing the driving safety or physical defects were suggested. The method for evaluation of results was elaborated. [结果]制订了有身高、远视力、色觉、血压、听力必查项目与有无妨碍驾驶安全或生理缺陷等检查项目及结果评定方法。
Results All 28 cases were successfully in implantation of posterior chamber artificial lens in the primary operation according to the follow-up survey. The cases with corrected distant vision beyond 0.3 accounted for 82.14%, and beyond 0.6 accounted for 39.28%. 结果28例患者均顺利Ⅰ期植入后房型人工晶状体,随访观察证实矫正远视力>0.3为82.14%,>0.6为39.28%,,无严重并发症出现。
Methods The Rondon Dot stereogram and synoptophore were used to examine, the acuity threshold, fusion field and response speed of distant and near stereopsis in 102 subjects with normal aged vision. 方法采用随机点立体图和同视机双项检测102例正常视力老年人远近立体视锐度阈值、立体融合范围及响应速度。
The refractive state, aniseikonia, fusion, binocular image, near and distant stereoscopic vision in120 cases ( 240 eyes) were observed. 分别检测双眼屈光状态、影像不等,融合功能以及远、近立体视功能。
Methods: Distant and near vision, positive and negative reserve of relative accommodative capabilities were measured on thirty one freshmen with normal vision by standard vision chart. 方法:应用标准对数视力表对31名视力正常大学新生进行远、近视力及相对调节力正、负贮备的测定。
But in many cases, We need to observe both the distant objects and the objects at close range clearly without changing the location of Binocular Vision System. It is difficult for the Fixed Focus Binocular Vision System to meet this need. 但在很多应用中,需要在不改变双目视觉系统位置的情况下,既能清晰的观察到远距离对象,也可以观察近距离的对象,定焦距的双目视觉系统很难适应这一需求。
Distant Vision was examined through E Standard Logarithm Eyesight Table. Integrated Optometry to determine the diopter and Best Corrected Visual Acuity ( BCVA). Axial length ( AL) measurements obtained through IOL-Master. 入选患者均行标准对数视力表检查,验光确定屈光度及最佳矫正视力(BCVA),并用IOL-Master测量眼轴长度。
