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:
“Still let my tyrants know, I am not doomed to wear
Year after year in gloom, and desolate despair;
A messenger of Hope comes every night to me,
And offers for short life, eternal liberty.”
—Emily Brontë (18181848)
“Through a series of gradual power losses, the modern parent is in danger of losing sight of her own child, as well as her own vision and style. Its a very big price to pay emotionally. Too bad its often accompanied by an equally huge price financially.”
