What the First Year of Life Looks Like Through the Eyes of a Baby

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.

Watch a Baby Polar Bear Open Its Eyes for the Very First Time

Sometimes, after a long week, all you need is something wholesome to lift your spirits. Here to do just that is the Berlin Zoo's newest resident.

In this polar bear video spotted by Geek.com, a 5-week-old cub can be seen opening its eyes for the very first time as its mom, Tonja (pronounced like Tania), cleans and cuddles it. “While it was previously only able to explore its surroundings by groping and cuddling, the little bear can now see and hear things,” according to a translated version of the zoo’s polar bear video caption.

Like kittens and puppies, polar bears are functionally blind and deaf when they’re born. It takes polar bears several weeks longer to develop their senses compared to puppies or kittens, though—about 30 days total. Their claws come later, too.

The diminutive nature of newborn cubs may also come as a surprise. Although full-grown adults can tip the scale at more than 1300 pounds, newborns weigh just 16 to 24 ounces—about the size of a guinea pig. But they pack on the pounds quickly, and can weigh over 100 pounds by the time they’re 8 months old.

A Berlin Zoo spokesperson reportedly said the cub has a big appetite and ate a lot over the holidays (just like the rest of us, apparently). It’s now attempting to walk, but mom and baby aren’t expected to leave the cave in their enclosure before spring arrives.

According to DW Science, zoo staff don’t know the sex of the cub yet. For its protection, they plan to give mom and baby lots of alone time before they approach. Newborn polar bears are quite vulnerable—especially in the wild, where about 85 percent of the bears die before they’re 2 years old.

Meanwhile, zoo staff are keeping a watchful eye on the cub, courtesy of the infrared cameras they have set up in their den.
