Our eyes detect color by a specialized cone cell.

我们的眼睛通过一种特殊的视锥胞来色。

There are three types of cone cell in the human eye.

人眼有三种视锥胞。

The cone cells in your eyes overlap in the wavelengths they detect.

你眼睛里的视锥胞在它们探测到的波长上重叠。

Whereas 3 types of cone cells absorb red, green, or blue light and provide a colored image.

而三种类型的视锥胞则吸收红、绿或蓝光并提供彩色图像。

Cleo, like most people, has three types of cone cells, each one sensitive to a different part of the spectrum.

克莱奥和大多数人一样， 有三种视锥胞，每种胞对光谱的不同部分敏。

Humans have trichromatic vision, meaning we have three cone cells in our retinas, each which are sensitive to different wavelengths of light: blue, green or red.

人类具有三色视觉，这意味着我们的视网膜中有三个锥形胞，每个胞对不同波长的光敏：分别是蓝色，绿色或红色。

Dr Schwartz and his team coaxed embryonic stem cells to become retinal pigment epithelium tissue which supports the rod and cone cells that actually respond to light

他的团队诱导胚胞成为视网膜色素上皮组织胞－其中的杆胞及锥晶胞对光线敏。

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， 正是你现在所使用的，它是我们通过眼睛的锥状胞记录的日间彩色视觉。

The limit to our vision doesn't come from being able to bring things into focus; it's because the cone cells on our retina are only packed so close together.

人类视力的极限其实不是源于聚焦的难度，而是视网膜上的锥状胞密度的极限。

Humans have trichromatic vision, meaning we have three cone cells in our retinas, each which are sensitive to different wavelengths of light; blue, green or red.

人类具有三色视觉， 这意味着我们的视网膜中有三个视锥胞，每个视锥胞对不同波长的光敏； 蓝色、绿色或红色。

Here, a massive grid of cone cells and rod cells absorb the photons of light and output electrical signals to a nerve fiber that goes to the brain for processing.

在这里，大量的视锥胞和视杆胞网格吸收光子并将电信号输出到通往大脑的神经纤维进行处理。

As NASA explains, even when 99 percent of the sun's surface is covered, the 1 percent that sneaks out around the edges is enough to damage the rod and cone cells in your retinas.

正如 NASA 所解释的，即使太阳表面的 99%被遮挡，仍有 1%的阳光从边缘漏出，足以损害视网膜上的杆胞和锥胞。

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色敏的视锥胞产生的，而暗视觉是由眼睛的杆状胞产生的，它们非常擅长事物的亮度，但不能区分不同的色。

Now this brings us to a key question: If your eyes only have 3 different types of cone cells, each of which can only absorb red, green, or blue, how do we see this entire spectrum of colors?

现在这给我们带来了一个关键问题：如果你的眼睛只有 3 种不同类型的视锥胞，每种胞只能吸收红色、绿色或蓝色，那么我们如何看到整个色谱呢？
