Diagnosing blindness in infants
A pediatrician will screen your baby for eye problems shortly after birth. At 6 months of age, have an eye doctor or pediatrician check your child again for visual acuity, focus, and eye alignment.
The doctor will look at your baby’s eye structures and see whether they can follow a light or colorful object with their eyes.
Your child should be able to pay attention to visual stimuli by 6 to 8 weeks of age. If your child doesn’t react to light shining in their eyes or focus on colorful objects by 2 to 3 months of age, have their eyes examined right away.
Have your child’s eyes examined if you notice crossed eyes or any other symptoms of impaired vision.
