Our eyes detect color by a specialized cone cell.

我们眼睛通过一特殊锥细胞来感知颜。

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

人眼有三锥细胞。

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

你眼睛锥细胞在它们探测到波长上重叠。

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，人眼只有三类型锥细胞，可以感知三主要颜：蓝、绿和红。

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，这意味着我们网膜中有三个锥形细胞，每个细胞对不同波长光敏感：分别是蓝，绿或红。

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胞成为网膜素上皮组织细胞－其中杆细胞及锥晶细胞对光线敏感。

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.

人类力极限其实不是源于聚焦难度，而是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， 这意味着我们网膜中有三个锥细胞，每个锥细胞对不同波长光敏感； 蓝、绿或红。

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.

我们正常亮光是由三对颜敏感锥细胞产生，而暗是由眼睛杆状细胞产生，它们非常擅长感知事物亮度，但不能区分不同颜。
