Night vision is the ability to see in low light conditions. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range. Humans have poor night vision compared to many animals, in part because the human eye lacks a tapetum lucidum.

Famous quotes containing the words night and/or vision:
“Chance does not speak essentially through words nor can it be seen in their convolution. It is the eruption of language, its sudden appearance.... It’s not a night atwinkle with stars, an illuminated sleep, nor a drowsy vigil. It is the very edge of consciousness.”
—Michel Foucault (1926–1984)
“Deep in the human heart
The fire of justice burns;
A vision of a world renewed
Through radical concern.”
—William L. Wallace (20th century)
