Binocular vision development in infants is typically complete by which age range?

Explanation:
Binocular vision relies on coordinated eye movements and the brain’s ability to fuse two slightly different images into one. In newborns these processes are not fully reliable, but by about 3 to 4 months most infants have stable eye alignment and can fuse images from both eyes, enabling depth perception. This marks the typical completion of early binocular vision development. If alignment remains inconsistent after this period, it could indicate a vision problem such as strabismus and should be evaluated. The other age ranges are either too early or too late for this maturation milestone.
