Night vision refers to the capability to see clearly in low-light or dark conditions. This ability allows individuals to navigate and perceive their surroundings effectively when natural light is minimal.

Specialized mechanisms in the human eye, particularly rod cells, play a crucial role in enabling night vision, as they are sensitive to lower levels of light compared to cone cells, which are responsible for color vision. This makes night vision particularly valuable for driving at night or in poorly lit environments, where visibility can be significantly reduced.

The other options don’t accurately define night vision. Seeing colors clearly pertains to well-lit conditions rather than low light, while judging distances is a visual skill unrelated to light levels. The ability to see below and above might refer to a range of vision, but it does not specify light conditions, making it irrelevant in this context.
