The alignment of the two is critical for clear vision, but being a fluid-filled ball, it is not going to stay in perfect alignment without an active control mechanism.

兩者的對齊對於清晰的視覺至關重要，但作為一個充滿液體的球，如果沒有主動控制機制，它是無法保持完全對齊的。

Your eyeball is in a constant state of adjustment based on where the light focuses, on, in front of, or behind the retina.

你的眼球會根據光線聚焦的位置（視網膜上、視網膜前或視網膜後）不斷進行調節。

If light focuses in front of the retina, the eyeball will try to shorten, axial reduction.

如果光線聚焦在視網膜前方，眼球就會試圖縮短，即軸向縮小。

If light focuses behind the retina, the eyeball will try to lengthen, axial elongation.

如果光線聚焦在視網膜後面，眼球就會試圖拉長，即眼球軸向拉長。

One reason light might focus behind the retina is your glasses.

光線可能聚焦在視網膜後面的一個原因是你‘的眼鏡。

Glasses to control nearsightedness will cause some of the light to focus behind the retina, called hyperopic defocus.

控制近視的眼鏡會使部分光線聚焦到視網膜後面，這被稱為遠視散焦。

This sends a signal to your eyeballs to increase axial length, elongating the eyeball to correct what it perceives as being too short.

這會向眼球發出增加軸向長度的信號，拉長眼球以糾正它所認為的過短。

Now that your eyeball is longer, light focuses even further in front of the retina, and you're even more nearsighted than before.

現在，你的眼球變長了，光線在視網膜前聚焦的距離更遠了，所以你比以前更近視了。

Higher and higher correction glasses can continue to cause the eyeball to elongate.

越來越高的矯正眼鏡會繼續導致眼球變長。
