How eyesight develops in young children

Vision is one of those things that form an integral part of our life. Being able to see a distance from you will ensure that you interact with everyone around you without an issue. To help you appreciate your vision, let us look at how your sight develops from when you were conceived. It will give you a better perspective on eye development and help you know what you need to look out for if your child has eye issues.

The eye development during gestation

There has been a lot of research done to see how the eye develops during birth. It was discovered that the eyes begin to develop on the 17th day after conception. On this day, the mesoderm cells in the growing fetus and the ectoderm, which form the middle and outer layers of the blastoderm, form the eye fields of the embryo. There will be optic vessels developing in the eye cells within five days after the eye fields have been formed,

By 30 to 35 days, you can see the start of the iris, and it will fully develop after two weeks. The optic stalk will also start growing as the iris develops. Most of the growth will keep going until the baby is fully developed and will keep happening after the baby is born.

How is a newborn’s sight?

A newborn sees things the way a 36 week fetus would perceive everything. Things are blurred, and there is no perception of objects like adults see it. Even though the eyes can see, the brain cannot comprehend what vision is at that time. The visual acuity in infants is 20/400 or 6/120, but this improves to around 20/25 by the time a child is six months old. The growth process is known as emmetropization, where the eyeball works to match the power of the eyes. Even though young kids have hypermetropia, it improves as they get into their teenage years. Hypermetropia is when the light rays focus beyond the retina.

The size of newborn eyeballs is two-thirds of what they will be when they are fully grown. They keep growing and developing as the child grows older.

Visual milestones

One of the issues many parents have is figuring out if their child’s vision is okay or if they need to see an eye specialist. Knowing what milestones to expect will enable you as a parent to keep in tune with your child’s development. Here are the visual milestones your child will go through.

  • Birth to 1 month. Your child responds to light and will blink. They can also see an object that is not more than 25 centimeters away, and they begin to follow slow-moving objects.

  • 1 to 2 months. The child can see images that are not more than 50 centimeters away and make out faces close to them. They also begin to develop tears.

  • 2to 5 months. Your child sees people more clearly even when they are further than 50 centimeters. They can also easily follow moving objects because their neck movement is improved.

  • 7 to 12vmonths. The child can see and follow small objects moving around. They also have a perception of depth and can see fast-moving objects.

These milestones cover up to 1 year, and these are the years where it is hard to spot any eye issues.

One of the things you need to do to ensure your child’s sight is developing normally is to go for a checkup. The doctors will spot anything that might be amiss and rectify it before it gets worse.
