night vision
C1Technical, Military, Everyday (when discussing technology).
Definition
Meaning
The ability to see in low-light or darkness.
The use of special technology (e.g., electronic devices, goggles) to amplify limited light (starlight, moonlight) or detect infrared radiation, enabling vision in darkness. Also used metaphorically to describe a deep or prophetic insight into a complex, 'dark', or uncertain situation.
Linguistics
Semantic Notes
Typically a noun phrase, often used attributively (e.g., 'night-vision goggles'). As a compound, it is commonly hyphenated when used adjectivally ('night-vision equipment') but may be open ('night vision') when used nominally. The metaphorical use is less common and often found in literary or analytical contexts.

Conceptual Metaphor
KNOWLEDGE/UNDERSTANDING IS LIGHT; IGNORANCE/UNCERTAINTY IS DARKNESS. Thus, 'night vision' can metaphorically mean the ability to gain insight where others see only confusion.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'ночное видение' for the technological sense; the established term is 'прибор ночного видения' (PNV) or 'ночной прицел'. 'Ночное зрение' typically refers only to biological capability.
- Do not confuse with 'nightmare' ('кошмар') or 'vision' as a dream ('видение').
Common Mistakes
- Using 'night view' incorrectly for the technology (e.g., 'He used night view to see' – incorrect).
- Misspelling as one word: 'nightvision'.
- Using it as a verb: 'He night-visioned the area' (incorrect; correct: 'He used night vision to scan the area').

FAQ
Frequently Asked Questions
It is most commonly written as two words ('night vision'). A hyphen is used when it functions as a compound modifier before a noun ('night-vision goggles').
Yes, but it is limited. Human eyes adapt to darkness over time (dark adaptation), allowing some vision in very low light, but it is far inferior to that of many animals and cannot compare to electronic night vision devices.
Night vision (image intensification) amplifies tiny amounts of visible and near-infrared light. Thermal imaging detects heat (mid- or long-wave infrared radiation) emitted by objects and does not require any ambient light.
Yes, though less commonly. It can describe an exceptional ability to understand complex, obscure, or future situations, as in 'The economist had a kind of night vision regarding the coming financial crisis.'
