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

但这代表你的视网膜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，因为它们的视网膜中没有必要的受体，所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.

像素140万，像素密度326ppi，真正的视网膜图像质量。

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

影像是被投射在老鹰眼睛后方的视网膜的。

But it can also cause damage to the retina in the back of the eye.

但它也会对眼睛后部的视网膜造成损害。

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

我们数据无线传输到显示器，它会数据投射到你的视网膜。

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

纳米颗粒附着在动物视网膜的感光细胞。

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

在眼睛的视网膜，同样形成错构瘤。

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

研究者们研究视网膜内特别的光敏细胞。

For example, when a 1969 study found that injecting mice with MSG caused severe damage to their retina and brain, some news outlets jumped to proclaim that eating MSG could cause brain damage.

例如，一项 1969 年的研究显示味精注入小鼠体内会对它们的视网膜和大脑构成严重伤害，一些新闻媒体便贸然断定食用味精会造成脑损伤。

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.

我们视网膜中的感光细胞？信号输入大脑深处，训练元与地球昼夜24小时循环同步。

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，足损害视网膜的杆细胞和锥细胞。

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膜专家的表现相适。

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射对视网膜造成的伤害造成的。

So, even though stars themselves are just tiny round dots, by the time the light reaches our retina, it's been smeared out into a starlike shape.

所即便恒星本身是圆点形，当光线抵达我们的视网膜时，还是会变成星星的形状。

But at night, there isn't enough light to activate these cones in your retina, and so your eyes rely on rods, which are much better at perceiving low light.

但在夜间，光线不足激活视网膜中的这些锥体细胞，因此你的眼睛依赖于杆状细胞，它们在低光环境下的感知能力更强。

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.

人类视力的极限其实不是源于聚焦的难度，而是视网膜的锥状细胞密度的极限。

University of Pennsylvania researcher Dr. Jean Bennett said she and her husband, Dr. Albert Maguire, first imagined using genetic medicine to treat retinal blindness in the mid-1980s.

宾夕法尼亚大学研究员吉恩·班纳特博士（Dr. Jean Bennett）表示，在世纪80年代中期，她和丈夫艾伯特·马奎尔博士（Dr. Albert Maguire）最先设想到利用遗传医学治疗视网膜疾病引发的失明。

Since these receptors function so differently, you might not be surprised to learn that your rods and cones are also wired to your retinas in different ways.

由于这些受体的功能如此不同，你能不会惊讶地发现你的视杆和视锥也不同的方式连接到你的视网膜。

A turn of the crown engages Night mode, which removes retina-altering blue light to ease the strain on your eyes in the dark.

旋转数码表冠，开启夜间模式。同时去除影响视网膜的蓝光，减轻双眼在黑暗中的压力。
