During the near point convergence test, the point at which the patient reports double vision is known as the _______ point.

In the near point convergence test, the correct term for the point at which the patient reports seeing double vision is indeed referred to as the "break" point. This point signifies the limit of how much convergence the eyes can achieve while focusing on a nearby target. The test measures the ability of the eyes to work together as they converge, typically by bringing a target closer to the patient until they can no longer maintain single vision.

When the subject experiences double vision, it indicates that the eyes have reached their maximum convergence, and this moment identifies the break point. This is an essential measurement in assessing binocular vision and detecting potential convergence insufficiency.

Each of the other terms doesn't accurately reflect this phenomenon. The limit might suggest a boundary, but it lacks the specific context of visual perception. Threshold relates more to a point of sensitivity or minimal stimulus and does not apply directly to the convergence test. Convergence could imply the action itself but does not define the specific moment when double vision occurs. Thus, break effectively captures the essence of this critical moment in the near point convergence evaluation.
