What is blindness?


Blindness is the condition of lacking visual perception due to physiological or neurological factors. Various scales have been developed to describe the extent of vision loss and define blindness. Total blindness is the complete lack of form and visual light perception and is clinically recorded as NLP, an abbreviation for "no light perception." Blindness is frequently used to describe severe visual impairment with residual vision. Those described as having only light perception have no more sight than the ability to tell light from dark and the general direction of a light source.

Famous quotes containing the word blindness:

    It is unheard-of, uncivilized barbarism that any woman should still be forced to bear such monstrous torture. It should be remedied. It should be stopped. It is simply absurd that, with our modern science, painless childbirth does not exist as a matter of course.... I tremble with indignation when I think of ... the unspeakable egotism and blindness of men of science who permit such atrocities when they can be remedied.
    Isadora Duncan (1878–1927)

    cried as he died, fearing at last the spheres’
    Last sound, the world going out without a breath:
    Too proud to cry, too frail to check the tears,
    And caught between two nights, blindness and death.
    Dylan Thomas (1914–1953)

    the heart,
    this child of myself that resides in the flesh,
    this ultimate signature of the me, the start
    of my blindness and sleep, builds a death crèche.
    Anne Sexton (1928–1974)
