How it's used
Refers specifically to the optical component used in scientific or technical contexts like cameras, microscopes, or glasses. While technically correct, everyday speech often prefers more specific terms like 鏡片 for glasses or camera lenses to avoid sounding overly academic or formal.

Common mistake
Do not confuse this with 鏡頭, which refers to the entire camera lens assembly or the lens of a camera, rather than just the piece of glass itself.
