From the 2017 US data, how many millions were living with blindness?

• A. 7.08
• B. 2.17
• C. 3.5
• D. 1.08

Answer: (D)

In public health data, “blindness” refers to a specific, strict category of vision loss, so the counts are relatively small compared to all levels of impairment. Using the 2017 US data, the number of people living with blindness is about 1.08 million. That figure corresponds to roughly 0.3% of the population, given the US population at the time. The other numbers are much larger and would imply a broader group (severe vision impairment or overall vision loss) rather than blindness as defined for surveillance counts. So, 1.08 million best fits the strict definition used in this data.
