Accommodation in Eye and Camera
眼睛和相机中的调节
Accommodation is the process of adjusting the focus distance of an optical instrument to the object which is to be viewed. This process is done very differently by the eye and a camera.
调节是指将光学仪器的聚焦距离调整到要观察的物体上。这个过程由眼睛和相机以非常不同的方式完成。

Accommodation from distant to close objects for the eye is done by rounding out the lens to shorten its focal length, since the image distance to the retina is essentially fixed. 眼睛从看远处物体调节到看近处物体时，是通过使透镜变凸以缩短其焦距，因为像距到视网膜基本上是固定的。 |
Accommodation from distant to close objects for the camera is done by moving the lens further from the film since the focal length is fixed. 为了从远处物体聚焦到近处物体，相机通过将镜头远离底片移动来实现，因为焦距是固定的。 |
