In Worth 4 Dot testing, seeing two red dots indicates suppression of which eye?

Explanation:
Worth 4 Dot uses red-green glasses to check how the eyes share visual input. The right eye sees red, the left eye sees green, and there’s a white dot that can be seen if both eyes contribute. When one eye is suppressed, that eye’s input isn’t incorporated into binocular perception, so the observer relies on the other eye for what’s seen. If the left eye is suppressed, the right eye provides the red stimulus and the fusion cue, which can be perceived as two red dots. This pattern points to suppression of the left eye (OS).
