Reduction of vision to ____/____ or less is considered complete loss of sight in an eye.

• A. 20/50
• B. 20/200
• C. 20/100
• D. 20/150

Answer: (B)

Legal blindness is defined by an acuity of 20/200 or worse in the better eye with the best possible correction, or a severely restricted field of vision. So if the vision in an eye is reduced to 20/200 or worse, that eye is considered legally blind, even if the other eye sees normally. The other visual acuities listed (20/50, 20/100, 20/150) are all better than the legal blindness threshold, so they do not meet the criterion for complete loss of sight in an eye. This 20/200 standard is the threshold used to designate legal blindness in many health and disability contexts.
