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:
“For the “superior morality” of which we hear so much, we too would desire to be thankful: at the same time, it were but blindness to deny that this “superior morality” is properly rather an “inferior criminality” produced not by greater love of Virtue, but by greater perfection of Police; and of that far subtler and stronger Police, called Public Opinion.”
—Thomas Carlyle (1795–1881)
“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)
“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)
