With the development of strabismus violated the right combination of eye, it becomes impossible to link images in a single picture. To compensate for failure in the functionality of the Central nervous system blocks the extra image that is served in the brain from the squinting eye. If the treatment of strabismus is missing, after some time, permanent locking leads to squinting eye develops amblyopia.
