Question

Under the National Programme for Control of Blindness, to define blindness, the visual acuity should be less than

• A. 3/60
• B. 6/60
• C. 1/60
• D. 6/24

Hint:

WHO/India's blindness cutoff is much stricter than normal driving vision.

Answer 1

The Correct Option is A

India's blindness control programme needed one fixed number to decide who is counted as blind in surveys and treatment planning.

1. 3/60: This is the accepted cutoff. Vision worse than this in the better eye, even after correction, is labelled blindness.
2. 6/60: This level is called low vision or severe visual impairment, a step above true blindness, not the defining cutoff.
3. 1/60: This vision is indeed within the blind range, but it is not the threshold number used to define the category.
4. 6/24: This is a mild to moderate level of visual impairment, well above the blindness range.

So among the four values, the one actually used as the official dividing line for blindness under the National Programme for Control of Blindness is 3/60.

Let's summarize:

• Normal vision is written as 6/6.
• Blindness in India's programme means vision less than 3/60 in the better eye after correction.

The correct answer is 3/60.
