Well, we start with a substrate that has a light-sensitive film on it.

我们从一个有一层感光膜覆盖的基底开始。

This area is covered with light sensitive cells known as cones.

这个区域被称为锥细胞的感光细胞所覆盖。

Doctors believe they need to fix one-tenth to one-third of the cells to repair vision.

医生认为，修复力需要修复十分之一至三分之一的感光细胞。

It damages those fine photoreceptors, which are used for sensing vision.

它损害了那些用于感知觉的细感光。

And some birds of prey have like 10 times more than we do.

有些猛禽的感光细胞数量是我们的 10 倍。

Compound eyes are made up of hundreds or even thousands of tiny light-sensitive units.

复眼是由成百上千个微的可感光的眼组成的，每个细胞只看到周围环境的一部分。

The nanoparticles attach themselves to photoreceptors in the animal's retina.

纳米颗粒附着在动物网膜上的感光细胞上。

A more complex version of this light spot can be found in the flat worm, planaria.

扁形动物中的涡虫 则拥有更复杂的感光点结构。

Sensors in the back of the eyes respond to changing light, transmitting crucial information to the brain.

位于眼睛后方的感光官会对光线的变化做出反应，并把重要讯息传递给大脑。

The OCT systems operated by ophthalmologists use low-power lasers which produce light with a wavelength of 850 nanometres.

眼科医生操作的OCT系统使用的是低功率激光，发出850纳米波长的光线，这刚好超出了眼睛杆锥层可感光的范围。

Basically, the more light that a single cell or single photo receptor can take in, it reduces the resolutions.

基本上，单个细胞或单个感光体吸收的光越多，分辨率就越低。

The Illum still uses a special sensor covered by a matrix of microlenses, which capture the entire light field.

新款Illum仍然使用微透镜阵列为矩阵式排列的特殊感光元件，从而可以捕捉全区的光场摄影领域。

But anyway, it turns out they're actually just a window that focuses photons onto a light-sensing tissue called the retina.

但不管怎样，事实证明它们就像一个有感光装置的窗户，那个装置就叫做网膜。

The light sensitive layer inside your eye is filled with tiny cells called photoreceptors.

你眼睛里的感光层充满了被称为光感受的微细胞。

Birds have an extra photoreceptor that allows them to see red incredibly well.

鸟类有一个额外的感光细胞，使它们极其敏锐地看到红色。

Photoreceptors contain thousands of molecules called photopigments, which are sensitive to particular colors.

感光细胞含有数千种被称为感光色素的分子，这些分子对特定颜色敏感。

At the back of the camera is a massive grid of microscopic light-sensitive squares.

在相机的背面有一个巨大的微感光方形网格。

Partly, because we have similar densities of photoreceptors in our eyes.

部分是因为我们眼中的感光密度相似。

The light-sensitive part of the eye and part of the camera are both encased in black.

眼睛的感光部分和相机部分都被黑色包围。

Looking at something bright causes many pigments in a photoreceptor to bleach.

盯着明亮的东西看会导致网膜感光细胞中的许多色素褪色。
