Definition: Amblyopia is commonly known as "lazy eye." The eye appears healthy, but visual information is not transmitted or recognized properly through the visual and neural systems. Amblyopia usually results from some type of developmental abnormality caused by a high uncorrected vision problem, a large difference in powers between the eyes, or possibly a crossed-eye. Amblyopia should be treated before the age of seven to avoid vision development problems.
