Night Vision

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:

    Because all night you have not turned to us or spoken
    It is time for you to wake;
    Charlotte Mew (1870–1928)

    We might hypothetically possess ourselves of every technological resource on the North American continent, but as long as our language is inadequate, our vision remains formless, our thinking and feeling are still running in the old cycles, our process may be “revolutionary” but not transformative.
    Adrienne Rich (b. 1929)
