If diplopia is the endpoint during testing, what does that indicate?

Explanation:
Diplopia as the endpoint means the binocular system can no longer fuse the two images into one; the eyes are no longer aligned under the added demand, revealing a binocular vision problem. This occurs when fusional vergence reserves are exceeded or when there’s a misalignment tendency, so you see two separate images instead of one. It’s not about refractive error (which causes blur, not double vision) and it’s not a normal or expected result in these tests.
