表观视野的范围由 78 名无经验的视觉观察者组成。我们发现少数人（不到 10%）基本上是真实的，但大多数人的视场只有约 90A 度，因此比眼睛屈光度所显示的（略高于 180A 度）要窄得多。这与现有的（尽管主要是轶事）证据非常一致，尽管迄今为止还缺乏正式数据。这一发现是在视野拓扑结构（“局部符号”的一个方面）的度量校准的背景下讨论的。
The extent of the apparent visual field was determined for a group of 78 na < ve visual observers. We find that there exists a minority (less than 10%) that is essentially veridical, but that the majority of the population experiences an apparent visual field of only about 90A degrees, thus much narrower than the dioptrics of the eye would suggest (a little over 180A degrees). This is in good accordance with available (albeit mainly anecdotal) evidence, though formal data have been lacking thus far. The finding is discussed in the context of metrical calibration of the topological structure of the visual field, an aspect of "local sign".
