Anyway, the reason I'd never heard of scotopic vision before is that most of us don't experience it much.
论如何,我以前从未听说过暗视觉原因是我们大多数人都没有太多验。
Whereas our normal, bright-light photopic vision is produced by three types of color-sensitive cone cells, dark scotopic vision is produced by the eye's rod cells, which are great at sensing something's brightness, but can't discriminate different colors.
我们正常亮光视觉是由三种对颜色敏感视锥细胞产,暗视觉是由眼睛杆状细胞产,它们非常擅长感知事物亮度,但不能区分不同颜色。
