[驗光師] 隱形眼鏡學與配鏡學
第 50 題
下列何者為漸進多焦點鏡片上的臨時性標記？
- A 稜鏡參考點
- B 近用附加度
- C 生產商標
- D 垂直標誌線
思路引導 VIP
請試著回想一副剛從工廠送到眼鏡店、尚未加工磨製的漸進鏡片：為了確保磨鏡師能精確地將度數中心對準患者的瞳孔，鏡片上會印有許多彩色線條。請思考，哪一類型的參考標記是僅為了『加工與檢驗定位』而存在，一旦眼鏡製作完成、要交給客人佩戴時，就必須被『擦拭掉』以避免干擾視線的？

Hrmm... What... Oh, so that's the right answer?
- (Mumble) Huh? Wha... (stretches) Ah, so you got it right. Good. Means you found the right path with these 漸進多焦點鏡片 (PAL)'s marks. Not that I'd know the right path myself, but... good for you. This stuff is... basic, I guess. Important for seeing, or something.
- Look, it's simple enough. There are the ones that are actually part of the lens, carved in there. Like some生產商標, or the ADD power, or a straight line. They're always there, even if the stupid ink rubs off. Those are the 永久性標記 (刻印).
