If a disparity falls within Panum's fusional area, what happens?

Explanation:
Panum's fusional area is the range of binocular disparity where the brain can combine the two images into a single percept. When the disparity falls within this zone, the visual system fuses the signals from both eyes, so you don’t see double; you perceive one image, and depth can still be perceived if the disparity is suitable. Outside of this area, the images cannot be fused, leading to diplopia. Suppression is another mechanism that can help avoid double vision in conditions where fusion isn’t possible, but within Panum's area fusion is the normal outcome.
