Stages of Vision in Infants

As we discussed in class, vision is the least developed sense at birth.  We briefly discussed the stages of focus in their vision, but I was interested to learn a little more about each stage.   After doing a little bit of research, I found a website that breaks vision development down by months.

At birth, a child’s vision is black and white.  They are only able to see up to 15 inches away.  They are not yet able to focus their eyes, so even facial recognition is difficult.  A fun fact I learned is that a baby’s eyes are 65% of their full size at birth.

Within the first month, infants become able to recognize colors.   Their eyes do not yet allow much light, which is why they are easily able to sleep with lights on.

In months 2-3, their eyes become much better at tracking objects.  As the article I read states, they are able to follow objects with their eyes and look from one object to another without moving their head.  Their sensitivity to light become greater during this stage, but it is still not equal to that of an adult.  In these months their vision also become significantly sharper.

In months 4-6 their ability to focus is achieved almost completely.  By six months their vision will be about as good as it is going to get.  Their ability to track objects and move their eyes quickly is perfected during this stage.  They will also be able to see and recognize all colors.

In months 7 to 12, their depth perception and ability to determine distance makes great progress.  Their hand eye coordination is also improved during these months.

I had not realized that there was this much to eye development.  The website I got most of my information from also offers some tips to promote eye development that are well worth looking at.  I added a link to the websites below.

  1. It’s very interesting to read about the developmental details of visions in babies,but it makes me wonder how do researchers know? It’s one thing to observe size growth and the ability of a child to move their eyes to track objects, but how do you know that a child only sees in black and white, or that their vision becomes sharper at a certain stage of development? My attempt to find out wasn’t very successful.

  2. i also wondered that, how they know? it’s kind of the same thing that dogs see black and white, how do they test that. that is interseting fact about children’s eyes being 65% the size.

  3. I just could not leave your website before suggesting that
    I extremely enjoyed the standard information a person supply for your guests?
    Is going to be again regularly in order to check up on new posts
