Our eyes detect color by a specialized cone cell.

我眼睛通过一种特殊视锥细胞来感知颜色。

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

人眼有三种视锥细胞。

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

你眼睛里视锥细胞在它探测到波长上重叠。

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

而三种类型视锥细胞则吸收红、绿或蓝光并提供彩色图。

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， 有三种视锥细胞，每种细胞对光谱部分敏感。

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，这意味着我视网膜中有三个锥形细胞，每个细胞对波长光敏感：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

团队诱导胚胎干细胞成为视网膜色素上皮组织细胞－其中杆细胞及锥晶细胞对光线敏感。

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，它是我通过眼睛锥状细胞记录日间彩色视觉。

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.

人类视力极限其实是源于聚焦难度，而是视网膜上锥状细胞密度极限。

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， 这意味着我视网膜中有三个视锥细胞，每个视锥细胞对波长光敏感； 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，大量视锥细胞和视杆细胞网格吸收光子并将电信号输出到通往大脑神经纤维进行处理。

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，即使太阳表面 99%被遮挡，仍有 1%阳光从边缘漏出，足以损害视网膜上杆细胞和锥细胞。

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.

我正常亮光视觉是由三种对颜色敏感视锥细胞产生，而暗视觉是由眼睛杆状细胞产生，它非常擅长感知事物亮度，但能区分颜色。

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?

现在这给我带来了一个关键问题：如果你眼睛只有 3 种类型视锥细胞，每种细胞只能吸收红色、绿色或蓝色，那么我如何看到整个色谱呢？
