Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'глазной камень' which sounds like a medical condition (e.g., cataract). In historical context, a descriptive phrase like 'исторический инструмент для удаления соринки из глаза' is necessary.
Common Mistakes
- Using it as a modern medical term.
- Confusing it with 'eyeshadow' or 'eyebrow stone'.
- Thinking it refers to a gemstone worn near the eye (like an eyepatch).
