Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to process inputs from one eye and over time favors the other eye. It results in decreased vision in an eye that otherwise typically appears normal. It is the most common cause of decreased vision in a single eye among children and younger adults.
The cause of amblyopia can be any condition that interferes with the focusing in early childhood. This can occur from poor eye alignment, Eye to be irregular in shape such that focusing is difficult, one eye is more nearsighted or farsighted than the other, or clouding of the lens of the eye. Once the root cause is eliminated, the vision is restored immediately, because the mechanism also includes the brain. Amblyopia can be difficult to detect, therefore, vision screening is recommended for all children aged four to five.
