The first is known as photopic vision and it's the one you're using now, it's our daytime  colour vision recorded by our eye's cone cells.

一种称为明视觉， 正是你现在所使用的，它是我们通过眼睛的锥状细记录的日间彩视觉。

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.

我们正常的亮光视觉是由三种对颜的视锥细产生的，而暗视觉是由眼睛的杆状细产生的，它们非常擅长知事物的亮度，但不能区分不同的颜。
