diopter的意思、翻譯和例句

是什麼意思

「屈光度」是用來測量透鏡或鏡片的光學強度的單位。它表示透鏡的焦距（以米為單位）的倒數。屈光度越高，透鏡的光學強度越強，能夠更有效地聚焦光線。屈光度通常用於眼鏡和隱形眼鏡的處方中，以幫助矯正視力問題，例如近視、遠視和散光。

用法：

在視力矯正中，屈光度用來表示眼鏡或隱形眼鏡的度數。當眼睛需要矯正時，眼科醫生會根據每個人的視力狀況開具適合的屈光度處方。這個單位不僅用於眼鏡，還用於其他光學設備，如相機鏡頭和望遠鏡。屈光度的數值可以是正數或負數，分別代表遠視和近視。

例句及翻譯：

例句 1：

我的眼鏡屈光度是-2.5，這意味著我有近視。

My glasses have a diopter of -2.5, which means I am nearsighted.

例句 2：

在選擇隱形眼鏡時，屈光度是非常重要的參考指標。

The diopter is a very important reference when choosing contact lenses.

例句 3：

這台望遠鏡的屈光度使它能夠清晰地聚焦遠處的物體。
