This is the same as human vision.

这和人类的视觉原理是一样的。

Counter shading might make an animal just barely disappear to our very awesome human vision.

反向阴影可能会让视力非常好的人基本看不到动物。

So, yes, human vision is fallible, but those mistakes that it makes can help us understand that wonderfully complex system.

所以，人类的视觉是会出错的，但是它犯的这些错误可以帮助我们理解这个奇妙复杂的系统。

Human vision doesn't rely on depth sensors.

人类视觉不依赖于深度传感器。

Neither was she ever seen by human vision to go at a great pace.

人类的视觉也从未见过她以极快的速度前进。

But not all illusions work that way. Some produce ghost effects, or afterimages, that take advantage of glitches in the physiology of human vision.

但并不是所有的错觉都是这样的。有些会利用人类视觉生理的故障产生幽灵效应或残影。

So that's the basic anatomy and event sequencing of human vision, but what I really want to talk about are those two types of photoreceptors — your rods and your cones.

这是人类视觉的基本解剖和事件排序，但我真正想谈的是这两种类型的光感受器——视杆细胞和视锥细胞。

But it's right at the limit of human vision, and for me it always defines what is the classical, which is always derived from the human form, its proportions and its limitations.

在我们视觉范围之内。对我来说，它总是定义什么是古典，它总是源于人类的形式，比例和局限性。
