Depends: Blindness is a general term. Legal blindness is a snellen visual acuity of less than 20/200 best corrected or a very small visual field. This is the big letter "e" on most charts.
A person with absolute blindness can not see any light.

Totally blind see nothing; near total blindness is light perception and hand motions vision. Any recordable vision is low vision: 20/2000-20/400 = profound; 20/200 - 20/100 = severe; and 20/80-20/50 = moderate. See color blindness, face blindness and others.
