Our eyes detect color by a specialized cone cell.

我们的睛通过一特殊的视胞来感知颜色。

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

有三视胞。

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

你睛里的视胞在它们探测到的波长上重叠。

In contrast, the human eye only has three types of cone cells which allow the perception of three main colors: blue, green, and red.

相比之下，只有三类型的视胞，可以感知三主要颜色：蓝色、绿色和红色。

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.

类具有三色视觉，这意味着我们的视网膜中有三个胞，每个胞对不同波长的光敏感：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

他的团队诱导胚胎干胞成为视网膜色素上皮组织胞－其中的杆胞及晶胞对光线敏感。

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.

类视力的极限其实不是源于聚焦的难度，而是视网膜上的状胞密度的极限。

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.

类具有三色视觉， 这意味着我们的视网膜中有三个视胞，每个视胞对不同波长的光敏感； 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对颜色敏感的视胞产生的，而暗视觉是由睛的杆状胞产生的，它们非常擅长感知事物的亮度，但不能区分不同的颜色。
