When babies are born, their eyes are not fully developed, and they can't see quite as well as adults can. They see things differently than grown-ups because their brain and eyes are learning how to work together.
At first, babies can only see things that are very close, like faces and other objects that are about 8-10 inches away. They are also not able to see colors very well until they are about three months old. When babies look around, their eyes move and focus on different things, and this helps them learn about the world around them.
As they grow, their vision improves, and they can start to see farther away. They will eventually learn to use both eyes together to see things in 3D, which helps them judge distances and depth.
It's important that babies get regular eye check-ups to make sure their vision is developing normally. If there are any problems with their vision, it's best to catch them early so that they can be treated and not interfere with their learning and development!
