This can only occur efficiently when the eyes are properly aligned. Ordinarily, our brain receives an image from each eye and unifies those images to make one clear picture. A binocular vision problem refers to a misalignment of the eyes. There are several types of visual dysfunction that can trigger migraines, but a common one is binocular visual dysfunction (BVD).
