Amblyopia (i.e. lazy eye) is a leading cause of permanent vision loss below age of 30 in developed societies. The incidence of this disease is about 6-7% in every population, independent of race or nationality. The main causes of amblyopia are mild childhood eye refractory problems (e.g. anisometropia) and/or eye movement disorders (e.g. squint), which result in a disturbance of visual cortical development. Failure to recognize the problem till 6 or 7 years of age makes the chances of recovery minimal. Irreversible consequences include the lack of binocular vision and impaired visual acuity in one eye. The degree of vision loss can vary from mild to complete blindness. This visual impairment not only creates a great hardship for the child, it can certainly limit future endeavors. Furthermore, if the good, non-amblyopic, eye becomes damaged (e.g. injury, illness) then the person immediately becomes visually disabled.
