In Worth 4 Dot testing, seeing four dots indicates what?

Explanation:
Worth 4 Dot testing checks whether both eyes are contributing to vision and whether one eye is being suppressed by using red-green glasses and a target with four colored dots. The left eye sees the green dots and the right eye sees the red dots. When the brain fuses the two eyes’ images without suppression, all four dots are perceived, which is described as flat fusion without suppression. If one eye is suppressed, you’d only see the dots from the non-suppressed eye (fewer than four dots). If the eyes are misaligned and diplopia occurs, the dots don’t fuse and may appear as separate images rather than a single four-dot perception. So seeing four dots means normal binocular function with no suppression.
