關於蔡司鏡片 - 眼鏡

請問是所有的蔡司鏡片，傾斜後都看得到識別標誌嗎?

日前訂購了一隻Gunnar的眼鏡，依照廠商介紹，應該是
使用蔡司的鏡片，但是多次調整角度都無法看到特殊
標誌。

寫信詢問蔡司原廠後，回覆如下 :

Our US labs engrave the Gunnar logo on the upper outside of the left lens on
Gunnar SV and ERGO HD lenses. That is how a customer would know it is a
Zeiss lens. It is possible for anyone with a laser engraver to replicate
this, however.

依照內容應該是說只會有Gunnar標誌於左側鏡片一角?但是後面一句
"with a laser engraver" 我的gunnar標誌不需要雷射裝置就看的到阿 ...
