By practicing this exercise daily, the retina will be gradually accustomed to brighter light. Progressively your eye can function efficiently at any range of light intensities.
通过每天的锻炼，视网膜能够逐渐适应较强的光线，你的眼睛逐渐地能够在较大范围的光线强度内正常工作。
Spitzer's infrared instruments return reams of data to Earth as the orbiting observatory gathers light from far reaches of the universe, light that is invisible to the naked eye.
斯皮策太空望远镜在沿着轨道旋转时，收集了来自广阔太空的各种光线，这些光线对于肉眼来说是不可见的，但红外设备可以观测到，观测结果形成数据被传回地球。
The iris works just like the iris on a camera; if it's a bright day, and lots of light tries to enter the eye, then the iris will close down limiting the amount of light that can enter.
虹膜的工作机理如同照相机的光圈。天气晴朗时，虹膜将会变小以限制通光量。
Light entering the eye forms an upside-down image on the retina. The retina transforms the light into nerve signals for the brain.
光线进入眼睛，在视网膜上形成了一副倒立的画面，视网膜将光线译成神经信号，脑子识别信号并将画面倒立回来，于是我们就知道我们看到的是什么画面了。
This is “the light of the knowledge of the glory of God” (2 Corinthians 4:6), and it is as immediately perceived by the Spirit-awakened heart as light is perceived by the open eye.
圣光在被睁开的双眼感知的同时，也被灵魂觉醒的心灵感知。
An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye.
形状不规则的角膜或晶状体会使光线无法在视网膜——眼球背面的感光膜上准确地聚焦。
So far, they know that light plays an important role in eye development, and that by depriving developing eyes of light, they can induce myopia in animals.
到目前为止，他们知道光在眼睛发育过程中发挥重要作用，通过阻碍动物眼睛发育过程中摄入的光，可以诱导动物近视。
Just as light passing through the atmosphere becomes bent and distorted, so too does light passing through the front part of the eye.
正如光线通过大气层时会发生畸变一样，光线通过眼的前部时也会走形。
Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors.
颜色是光谱(与波长相对应的光能)与眼睛里敏感的光线感受器相作用的结果。
Massage when the light is not too bright, try not to direct eye, it is best to use reflective light, so that the baby will have a sense of security, massage comfortable and happy.
按摩时的光线不要太亮，尽量不要直射眼部，最好是用反射光线，如此会让宝宝有安全感，按摩时舒服又开心。
Visual light or perceived color is the quality of light emission as recognized by the human eye.
可见光或可分辨的颜色是人眼所辨认出的发射光的性质。
During the procedure, you'll be asked to focus on a point of light. Staring at this light helps you keep your eye fixed while the laser reshapes your cornea.
在手术过程中，会要求你注视一个光点，瞪视着它，这样激光改造角膜时有助于你的眼睛保持固定。
The lens focuses light rays on the retina - the layer of light-sensing cells lining the back of the eye - to produce a sharp image.
晶状体将光线聚焦于视网膜(排列在眼底的一层光敏细胞)来产生清晰的视觉影像。
Light stimulates that part of the brain that promotes arousal and vigilance, and eye shades are an absolute necessity for anyone who has any sort of ambient light coming in the room.
光线会刺激大脑，让我们持续清醒和警觉的状态。要是环境光线对你有影响，那眼罩绝对是个睡觉必备。
Electric eye head, strong anti-interference ability, it will not be affected by all kinds of visible light, infrared light and non modulated interference error trigger.
电眼头，抗干扰能力很强，它不会受到各种可见光，非调制红外光的干扰和误触发。
Reading or studying in this light takes more "eye energy" than in the natural light of day because artificial lighting doesn't include the full light spectrum.
在灯下阅读或学习会比在白天的自然光下消耗更多的眼睛能量，因此人造灯光里不是全光谱。
In the back of your eye there is a thin layer of tissue that contains millions of tiny light-sensing nerve cells called rods and cones. Cones respond to specific wavelengths of light.
眼睛后方，存在一种包含数百万感光神经细胞的薄层组织，我们称之为杆状细胞、圆锥细胞。
