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:
“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)
“... that great blindness which we are all under in respect to our own selves.”
—Molière [Jean Baptiste Poquelin] (1622–1673)
“It amazes me when I hear any person prefer blindness to deafness. Such a person must have a terrible dread of being alone. Blindness makes one totally dependent on others, and deprives us of every satisfaction that results from light.”
—Horace Walpole (1717–1797)
