When a baby is born, they enter a world that they’re not quite ready to perceive in its entirety. Their delicate senses slowly develop over a period of time, and they use these senses in a few different ways to explore the world in which they now live. One of these senses is sight; babies join the world with a rudimentary sense of it, but it improves over time.

Ensuring that your baby’s eyesight is developing appropriately and correctly is fundamental to their growth and development. This process can be confusing, however,  39DollarGlasses is happy to explain how infant eyesight develops in four simple steps.

Birth to four months: Color and coordination

Newborns have a very limited sense of sight, distance, and color. When born, they can only see objects that are very close to them, and their eyes tend to fixate on soft-bordered objects like faces that are about a foot away. Eye movements at this stage can be erratic. In fact, some babies may appear cross-eyed as their eye coordination has not calibrated itself.

An important milestone to watch for to help your baby develop is when their eyes correct themselves and look straight forward. If this does not happen after four months, you should see a doctor. Babies slowly develop a sense of color and contrast at this stage as well

Five to eight months: Motor skills and depth perception

At this age, babies will have developed some small motor skills tied to hand-eye coordination, namely reaching for things. The most important development in this stage is that of depth perception. As a baby’s eyes coordinate themselves, they can perceive the relative distance of objects. This allows them to explore more motor functions, as they can now see how close and far away their hands are from them, as well as other objects (now is the time for peek-a-boo!)

This is also the stage where babies begin to mimic and learn facial expressions from their parents, which is crucial for social development later on. If your baby doesn’t seem to reach for things or look you in the face, you may consider consulting your child’s pediatrician to ensure development is on track.

Nine to twelve months: Motion and hand-eye coordination

At this point in time, a baby’s depth perception will have improved enough to make tasks like standing up and attempting to walk much easier. If your baby is having vision issues at this stage, it might also be the time to think about whether or not glasses will be a wise investment for your child a little bit later in life. Resources like 39 Dollar Glasses can help you decide what types of eyewear might be best for your child, as well as make it easy on your pocketbook.

If everything is going perfectly, another skill that a baby will reveal at this stage may include the ability to recognize people they know when they’re approaching, which is both exciting for everyone involved and a big leap in social development.

Twelve months and beyond: Exploration

By this stage, a baby’s vision development has reached normal adult levels. Using their exciting, refined sense, babies will continue the same exploratory behavior of grabbing things, reaching out, walking (and tumbling!) around, and getting a sense for how the world looks and how their body operates in space.

It’s also a great time to check your baby’s eyesight, since it will be at the same development point until much later on in life. If glasses are recommended at this stage, you can also rest easy knowing that 39DollarGlasses.com has eyeglasses to suit even the little ones — so your bundle of joy can grow up to be a sharp-sighted bundle of accomplishment.
