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:
“Indeed, my mother’s beautiful face still shone with youthfulness that night when she so softly held my hands and sought to stop my tears; but, precisely, it seemed to me that this should not have happened, her anger would have saddened me less than this new sweetness that my childhood had never known; it seemed to me that, with a hidden and impious hand, I had just traced the first wrinkle and made appear the first grey hair in her soul.”
—Marcel Proust (1871–1922)
“Redeem
The time. Redeem.
The unread vision in the higher dream
While jewelled unicorns draw by the gilded hearse.”
—T.S. (Thomas Stearns)
