During the first four months, their visual horizon will expand from a few centimetres to many metres. Their vision will become clearer and colour vision will begin to develop. Their two eyes will start working together. By four months of age, an infant’s colour vision is similar to an adult’s, 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 lazy eye.
Lazy eye, or amblyopia, is another condition that becomes 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 eight years of age, it will often resolve completely. 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.
Visual abilities play a big role in early development. doctors of optometry recommend infants have their first eye exam between six and nine months of age. Children should have at least one eye exam between the ages of two and five, and yearly after starting school. An optometrist can complete an eye exam even if your child doesn’t know their ABCs. A doctor of optometry can use shapes, pictures and other child-friendly ways to evaluate vision and eye health.
