Amblyopia, colloquially called lazy eye, impacts the vision of some young children, rendering one eye weaker than the other. The brain ignores the weaker eye in favor of the stronger eye, which is forced to compensate. Left untreated, amblyopia can lead to permanent vision loss in the lazy eye and may even cause total blindness. The condition affects two to three percent of the population.
To see better, a child with a lazy eye might shut one eye or squint. In some children, one eye wanders, or the eyes appear to gaze in opposite directions. Amblyopia can make it difficult to judge distances. Some children begin tilting their heads to see better. These symptoms often go unnoticed, which is why vision screening and examinations are essential for young children.
