Newborns have all the ocular structures necessary to see, although these are not yet fully developed. At birth, your baby can see blurred patterns of light and dark. During the first four months, their visual horizon will expand from centimeters to meters. Their vision will become clearer as their eyes start working together and colour vision will begin to develop. By four months of age, an infant’s colour vision is similar to an adults’, and by the sixth month, your baby will acquire eye movement control and develop eye-hand coordination skills.

For the first six months, an infant’s eyes can appear slightly crossed or out of alignment, but this is usually normal. But if your infant’s eyes appear significantly crossed or remain misaligned after six months of age, contact your Doctor of Optometry right away; your child may have strabismus, commonly known as “crossed eyes”, a condition that needs to be treated with eyeglasses, contact lenses, prisms and/or vision therapy and, in some cases, surgery. In time, if not corrected, the ignored eye will become unable to function normally and will become largely unused. This may result in the development of a “lazy eye”. 

Lazy eye, or amblyopia, is another condition that can become apparent within the first six months of your baby’s life. This condition describes weak vision or vision loss in one eye as a result of an uncorrected prescription. If detected or treated before ten years of age, it will often resolve completely so that both eyes can see properly. It’s important to treat amblyopia early – with vision therapy, eyeglasses and/or contact lenses, or patching – as treatment becomes very difficult later on. Untreated, amblyopia can lead to blindness in the affected eye.
