Noun: 1. The ability to see in reduced illumination (as in moonlight): "Night-sight" refers to the natural or enhanced visual capability to perceive objects and navigate in low-light conditions, such as during nighttime, twilight, or under moonlight. It is often associated with the physiological adaptation of the eyes or the use of technological aids.
The term "night-sight" is used to describe visual performance in darkness. It is a compound noun, typically used in contexts discussing biology, military technology, or outdoor activities. * As a subject: "The soldier's night-sight was crucial for the covert operation." * As an object: "Owls possess exceptional night-sight." * With a possessive: "The device improved his night-sight significantly."
