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.

第一种称为明视觉， 正是你现在所使用，它是我们通过眼睛锥状细记录日间彩色视觉。

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.

我们正常亮光视觉是由三种对颜色视锥细产生，而暗视觉是由眼睛杆状细产生，它们非常擅长知事物亮度，但不能区分不同颜色。
