What is the definition of legal blindness in terms of visual acuity?

Legal blindness is defined as having a visual acuity of 20/200 or worse in the better eye with the best possible correction. This means that a person with this level of vision can see at 20 feet what a person with normal vision can see at 200 feet. This definition is critical for various legal and social purposes, including determining eligibility for certain benefits and services designed for individuals with significant visual impairments.

In this context, while the other choices might represent degrees of vision loss, they do not meet the threshold established for legal blindness. For instance, 20/100 and 20/50 indicate that a person has better visual acuity than the threshold required and therefore would not qualify as legally blind. The 20/250 designation similarly does not reach the threshold, as it indicates that a person sees worse than 20/200, but in legal definitions, the specific cutoff is established at 20/200.
