What visual acuity qualifies a person as legally blind?

• A. 20/100
• B. 20/200
• C. 20/40
• D. 20/20

Answer: (B)

A person is considered legally blind when their visual acuity is 20/200 or worse in the better eye with correction, or if their visual field is severely constricted. The measurement of 20/200 means that what a person with normal vision can see at 200 feet, a legally blind person can only see at 20 feet. This standard is used to determine eligibility for various services and assistance for individuals who are visually impaired. The other options, while indicating different levels of visual acuity, do not meet the criteria for legal blindness. For instance, 20/100 indicates that a person can see at 20 feet what someone with normal eyesight can see at 100 feet, which does not qualify as legally blind. Similarly, 20/40 and 20/20 are both considered acceptable levels of vision, with 20/20 representing normal vision. Thus, the only threshold that qualifies an individual as legally blind is 20/200.
