Which term defines a visual acuity of 20/200 or greater in the better eye after correction or 20/200 or less without correction?

The term that correctly defines a visual acuity of 20/200 or greater in the better eye after correction or 20/200 or less without correction is "legally blind." This classification is used to establish the level of visual impairment an individual experiences and has specific criteria set by legal definitions, often for the purposes of eligibility for benefits or services.

While many might associate blindness with the complete absence of sight, legally blind refers to those who, even with corrective lenses, have limited visual acuity that significantly affects their ability to perform daily tasks safely and effectively. Understanding this definition is crucial in music therapy and other supportive services, as it guides how practitioners tailor their approaches to meet the needs of individuals with visual impairments.

Other terms like "low vision" or "functionally blind" refer to varying degrees of visual impairment but do not encapsulate the specific legal standards associated with the term in question. Therefore, "legally blind" is the most accurate term in this context.
