👓　近視相關會話

⊙　問度數

＊　How strong are your glasses?   　你近視幾度

＊　What’s your glasses prescription?　

（國外不太會直接問近視幾度，在驗完光後眼科醫師會給一張處方簽，寫著視力和度數。因此詢問你眼鏡的處方是多少？等同問你近視或是遠視幾度）

＊　How bad is your eyesight ? 

⊙　回答　　diopter 分正的跟負的，如果是負數（例如-4.5 D 代表近視450度）；如果是正數（如+2.0 D 代表遠視200度）；如果已經把近視或是遠視講出來時，就不用加正負符號

diopter  ［daɪ'ɒptə］　屈光度
I am nearsighted with 7.5 diopters = I am minus 7.5 diopters    近視750度
I am farsighted with 1.0 diopters = I am plus 1.0 diopters     遠視100度

I have 20/20 vision ＝ 視力1.0
 
美國表達視力的說法，視力「0.8 = 20/25 vision」，視力「0.1 = 20/200 vision」，描述方式一定是「20/xx」，分子永遠是20

「20/20」 說法的意思是，板子通常擺在20英尺遠的地方，而你可以清楚看到20英尺處，別人也可以看到20英尺處，代表你的視力正常1.0；如果是20/200 vision，指你可以清楚看見20英尺處，但是其它人卻可以清楚看見200英尺處，代表你的視力不太正常，只有0.1
