But that means that retinas in your eyes are not catching the light, either.

但这代表你的视网也无法捕捉到任何光线。

They can't see the color red because they don't have the necessary receptors in their retinas for that, so they only perceive variations of blue and green.

它们看不到红色，因为它们的视网中没有必要的受体，所以它们只能看到蓝色和绿色的变化。

It's 1.4 million pixels and it's 326 pixels per inch, so true retina image quality.

140万，密度326ppi，真正的视网图质量。

Apple has totally re-engineered the screen, it's becoming a liquid retina screen.

苹果完全重新设计了屏幕，它正在变成一个液体视网屏幕。

Exposure to bright outdoor light stimulates the production of dopamine in the retina.

暴露在明亮的室外光线下会刺激视网中多巴胺的产生。

Images are projected onto the retina at the back of the eagle's eye.

影是被投在老鹰眼睛后方的视网上的。

This is the retina, which is like the back wallpaper lining layer of the eye.

这是视网，就眼睛的背面壁纸衬里层。

We can pass data wirelessly to that display and it projects it onto your retina.

我们可以将数据无线传输到显示器上，它会将数据投到你的视网上。

Each eye has about 120 million rods inside the retina.

每只眼睛在视网约有 1.2 亿棒体细胞。

We're using a diffraction to reflect the light directly in on human's retina.

我们正在使用一种衍法将光线直接反到人类视网上。

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

纳米颗粒附着在动物视网上的感光细胞上。

Crap, I knew I should've spent the extra money on a retina scanner.

糟糕，我就知道我应该多花钱买个虹扫描仪的。

Finally, in the retina, the light sensing part of the eye, hamartomas can form.

在眼睛的视网上，同样可以形成错构瘤。

Researchers looked at the role of specialized photosensitive cells in the retina.

研究者们研究视网特别的光敏细胞。

Not just the lens in front but the retina in back too.

不止可以拍到晶状体还可以拍到视网。

Light comes in through the cornea and pupil and hits the lens — the convex, transparent disc that focuses that light and projects it onto the retina, which makes up the inner layer of the back of the eyeball.

光线通过角和瞳孔进入并到达晶状体——凸起的透明圆盘，将光线聚焦并投到视网上，视网构成眼球背面的层。

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，足以损害视网上的杆细胞和锥细胞。

Light sensitive cells in our retinas feed signals deep into that brain region, training neurons to sync up with Earth's 24 hour cycle of day and night.

我们视网中的感光细胞？将信号输入脑深处，训练神经元与地球昼夜24小时循环同步。

Here is also a different way of aggregating this data – the algorithm did significantly better than all of the optometrists and matched the performance of the number one retina specialist.

这是另一种汇集起这些数据的方法——该算法的表现明显好于所有验光师，并与排名第一的视网专家的表现相适。

Looking at even the uneclipsed Sun for more than a moment is painful, and that pain is the result of the damage that solar radiation is doing to your retinas.

即使是看着不处于日食中的太阳超过一分钟也很痛苦，这种痛苦是由于太阳辐对视网造成的伤害造成的。
