Babies learn to see over a period of time, much like they learn to walk and talk. They are not born with all the visual abilities they need in life. The ability to focus their eyes, move them accurately, and use them together as a team must be learned. Also, they need to learn how to use the visual information the eyes send to their brain in order to understand the world around them and interact with it appropriately.
From birth, babies begin exploring the wonders in the world with their eyes. Even before they learn to reach and grab with their hands or crawl and sit-up, their eyes are providing information and stimulation important for their development.Healthy eyes and good vision play a critical role in how infants and children learn to see. Eye and vision problems in infants can cause developmental delays. It is important to detect any problems early to ensure babies have the opportunity to develop the visual abilities they need to grow and learn.Parents play an important role in helping to assure their child's eyes and vision can develop properly. Steps that any parent should take include:
At birth, babies can't see as well as older children or adults. Their eyes and visual system aren't fully developed. But significant improvement occurs during the first few months of life.The following are some milestones to watch for in vision and child development. It is important to remember that not every child is the same and some may reach certain milestones at different ages.
From birth to 4 months
At birth, babies' vision is abuzz with all kinds of visual stimulation. While they may look intently at a highly contrasted target, babies have not yet developed the ability to easily tell the difference between two targets or move their eyes between the two images. Their primary focus is on objects 8 to 10 inches from their face or the distance to parent's face.
During these months, control of eye movements and eye-body coordination skills continue to improve. Depth perception, which is the ability to judge if objects are nearer or farther away than other objects, is not present at birth. It is not until around the fifth month that the eyes are capable of working together to form a three-dimensional view of the world and begin to see in depth.
From 9 to 12 months
At around 9 months of age, babies begin to pull themselves up to a standing position. By 10 months of age, a baby should be able to grasp objects with thumb and forefinger. By 12 months of age, most babies will be crawling and trying to walk. Parents should encourage crawling rather than early walking to help the child develop better eye-hand coordination. Babies can now judge distances fairly well and throw things with precision.
From 1 to 2 years old
By 2 years of age, a child's eye-hand coordination and depth perception should be well developed.
The presence of eye and vision problems in infants is rare. Most babies begin life with healthy eyes and start to develop the visual abilities they will need throughout life without difficulty. But occasionally, eye health and vision problems can develop. Parents need to look for the following signs that may be indications of eye and vision problems:
The appearance of any of these signs should require immediate attention by your optometrist.
There are many things parents can do to help their baby's vision develop properly. The following are some examples of age-appropriate activities that can assist an infant's visual development.
From birth to 4 months
From 5 to 8 months
From 9 to 12 months
From 1 to 2 years
