Translation guide
The physical eyeball, as distinct from the eye area or eyesight. In Japanese, the most common word is 目 (me), which covers both 'eye' and 'eyeball' in many contexts. For explicit anatomical reference, 眼球 (gankyū) is used.
Referring specifically to the spherical organ itself, often in medical, scientific, or descriptive contexts.
The standard anatomical term for 'eyeball'. Used in medical contexts, biology, and when you need to be precise about the organ.
眼球の構造を勉強しています。
I'm studying the structure of the eyeball.
彼は事故で眼球を損傷した。
He damaged his eyeball in an accident.
The general word for 'eye'. In everyday conversation, 目 is used for the eyeball as well as the surrounding area. Context usually makes it clear.
目 can also mean eyesight, gaze, or the entire eye region. Use 眼球 when you need to be unambiguous about the organ.
目にゴミが入った。
I got something in my eyeball.
Literally 'eye ball', this is a colloquial term. It can sound childish or informal, and is often used in compound words or expressions.
目玉焼き
fried egg (sunny-side up, literally 'eyeball fry')
Informal English meaning 'to look at closely' or 'to estimate visually'. This is slang and does not have a direct Japanese equivalent as a single verb.
There is no single Japanese verb for 'to eyeball'. Use じろじろ見る (to stare rudely) or 目測する (to estimate by eye) depending on the nuance.
Direct translation of 'eyeball' as a verb will not be understood. Use context-appropriate phrases.
彼は私のことをじろじろ見た。
He eyeballed me. (stared at me rudely)
距離を目測する。
Eyeball the distance. (estimate by eye)
