Vision Development: 4-6 Months

Huge advances in vision development have occurred in the brain by 6 months old.  Visual acuity is now estimated to be approximately 20/25.  Color vision is normal.

If your baby’s eyes still look crossed from about 4-6 months of life, it is time to take your baby in for an eye examination with a developmental optometrist or ophthalmologist.  Sometimes you baby’s eyes might look crossed, but they really are not.  That is because your baby might have a flat nose bridge.  This creates what is called a “pseudo-strabismus.”  The nasal part of the eyelids partially cover some of the white part of the eye.  This gives the illusion of crossed eyes because you see less “white” (sclera) of your baby’s eyes.  Your eye doctor can tell for sure if your baby has crossed eyes that will require treatment, or pseudo-crossed eyes that does not require any treatment (this illusion goes away as your baby grows).

Note that American Optometric Association (AOA) has a program called Infant See ®.  Optometrists in your area will give your infant under 1 year old a FREE vision assessment.  This is a great place to start appropriate vision care for your baby.

March 2012 newsletter will take Edina up to 1 year old.  Amazing how quickly time passes!  Many thanks to my daughter and graphic designer, Annie, for capturing such special moments on film and video.

Development does not always progress in a smooth manner.  All children develop at their own rate.

I am blessed to be a part of my child’s and grandchild’s life.
