Reduction of vision to what level is considered complete loss of sight in an eye?

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

Answer: (D)

Complete loss of sight in an eye is defined as a visual acuity of 20/200 or worse. This level signifies that a person can see at 20 feet what a person with normal vision can see at 200 feet. In terms of legal classifications, individuals who have visual acuity at this threshold or lower may be considered legally blind. Visual acuity measurements like 20/50, 20/100, and 20/150 indicate progressively worsening vision, but they do not reach the threshold where an individual is classified as having complete loss of sight. The distinction at 20/200 is significant not only for clinical assessment but also for determining eligibility for various supportive services and interventions related to vision impairment. Thus, recognizing 20/200 as the benchmark for complete loss of sight is crucial in both a medical and legal context.
