Your eyes work a lot like a camera.
人的眼睛像照相机一样工作。
The lens of a camera focuses light onto the film inside.
照相机的镜头将光线聚焦到内部的胶片了。
The cornea and lens in the front of the eye focus light onto the back, where light-sensitive tissue called the retina is located.
眼睛前面的角膜和晶状体将光线向后聚集，聚焦在称为视网膜的感光组织上。
When the retina receives an image, it sends a signal through the optic nerve to the brain for the image to be developed.
当视网膜接收到图像后，它将信号通过视神经传到大脑，在那里图像被处理（形成视觉）。
