A baby's vision undergoes a series of significant developments during its first year of life, and these developments have been visually replicated, month by month, in a recent video from Tech Insider.

The unfortunate news for any parent who has ever felt like their newborn was gazing into their eyes: Until the third month, babies can't actually identify facial features, which include eyes and mouths. Also, they can't focus their eyes on any subject more than 10 inches from their face for the first three months.

At the 6-month mark, babies are finally able to construct a 3D view of the world—something that later comes in handy at 9 months, when their eye-hand coordination is finally developed enough to grab hold of objects.

Though humans' eyes aren't fully developed until age 2, babies do have a leg up on adults in one area: A 2016 study found that babies between the ages of 3 and 4 months old can see slight differences in images caused by changes in illumination, while adults cannot.
