Feedback: Blindness is defined as a best corrected visual acuity (BCVA) that can range from 20/400 to no light perception (NLP). The clinical definition of absolute blindness is the absence of light perception. Legal blindness is a condition of impaired vision in which a person has a BCVA that does not exceed 20/200 in the better eye or whose widest visual field diameter is 20 degrees or less. This makes options A, C, and D incorrect.
