Meaning and Usage
The word 眼球 (がんきゅう) specifically refers to the eyeball, the spherical part of the eye itself. It is a formal and anatomical term often used in medical, scientific, or descriptive contexts rather than everyday casual conversation.
Common Contexts
You will most often encounter 眼球 in medical examinations (眼球検査), anatomy discussions, or detailed descriptions of eye movement and health. It is less common to use this word when simply talking about eyes in daily life, where 目 (め) is more typical.
Collocations and Patterns
- 眼球検査 (がんきゅうけんさ): eyeball examination, used in medical checkups.
- 眼球運動 (がんきゅううんどう): eyeball movement, often in scientific or physiological contexts.
- 眼球を動かす: to move the eyeball, describing physical action.
Register and Nuance
This term is formal and technical. Using 眼球 in casual conversation might sound overly clinical or stiff. For everyday use, 目 (eye) is preferred.
Common Learner Mistake
Learners sometimes confuse 眼球 with 目, but 眼球 refers strictly to the eyeball itself, not the eye as a whole or the act of seeing. Avoid using 眼球 when you mean "eye" in a general sense to sound more natural.
