Transcript:Understanding Infant VisionHi, I'm Kathy Moore for About.com. Have you ever wondered how well or how much your baby can see? This program will explain infant vision and help you understand how a baby's eyesight develops over time.
Infant Sight at BirthAt birth, infants really cannot see very well at all. If you were able to measure it, your newborns sight would only be about 20/400. Over the next weeks and months, a baby's eyesight is steadily improving though some babies will not achieve 20/20 vision until they are about 2 years old.
Early Newborn VisionA newborn can focus best on objects about 1 foot from their eyes. Newborns have about a 90 degree range of vision and can see in color but do not necessarily distinguish all colors clearly. However by one to two weeks, infants can already begin to recognize features of their mothers face.
As their vision develops, infants show preference for certain bold patterns like stripes. Babies prefer bold colors and patterns because it is easier for them to see high contrast objects.
Vision at 6-8 WeeksBy 6 to 8 weeks, babies can fix their gaze on an object and follow moving objects too. At about 4 months, infants develop coordination between both eyes, which allows them to perceive depth and learn about spatial relationships. Once they can see more clearly, babies will begin batting at objects and reaching for toys that are within their field of vision.
Infant Vision ConcernsIf you notice your baby's eyes seem to move independently or become crossed after 4 months you should request an examination from your doctor. This may be caused by a condition known as strabismus wherein the eyes do not align properly.
Fully Developed Baby VisionIn many babies, vision is fully developed by the time they are 6 months old. At this point they can distinguish colors clearly and focus on objects both far and near.
Understanding what your baby can see will help you open their eyes to an interesting and healthy childhood. Thanks for watching. To learn more visit us on the Web at About.com.
