Our eyes detect color by a specialized cone cell.

我睛通过一种特殊视锥细来感知颜色。

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

人有三种视锥细。

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

你睛里视锥细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， 有三种视锥细，每种细对光谱不同部分敏感。

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，这意味着我视网膜有三个锥形细，每个细对不同波长光敏感：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

他团队诱导胚胎干细成为视网膜色素上皮组织细－杆细及锥晶细对光线敏感。

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.

人类视力极限实不是源于聚焦难度，而是视网膜上锥状细密度极限。

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，它是我通过睛锥状细记录日间彩色视觉。

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， 这意味着我视网膜有三个视锥细，每个视锥细对不同波长光敏感； 蓝色、绿色或红色。

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和锥细。

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，大量视锥细和视杆细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。

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产生，而暗视觉是由睛杆状细产生，它非常擅长感知事物亮度，但不能区分不同颜色。

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：如果你睛只有 3 种不同类型视锥细，每种细只能吸收红色、绿色或蓝色，那么我如何看到整个色谱呢？
