Typical near point of convergence break value is approximately:

• A. Around 6–10 cm.
• B. Around 25–30 cm.
• C. Around 1–2 cm.
• D. Around 40–60 cm.

Answer: (A)

Near point of convergence tests how close the eyes can be while still maintaining single, fused vision as a target is moved toward the nose. The break value is the distance at which fusion can no longer be maintained and diplopia appears. For a typical healthy reader or adult, that break distance is about 6 to 10 centimeters from the eyes. This range reflects normal convergence ability required for tasks like reading at typical desk distances. So the option around 6–10 cm matches the common normative NPC break value. The other distances—much farther (25–30 cm or 40–60 cm) would suggest weaker convergence reserves, and an extremely close value (1–2 cm) is not typical for normal binocular function.
