* The child has the ability to neutralize one of the two images to prevent double vision: the elimination of the phenomenon; if it is permanent -> final and irreversible => functional amblyopia * The convergent strabismus is the most common; it is secondary to the farsightedness; phenomenon of accommodation for vision correction -> convergence.…
