The doctor can appoint sticking up of an eye with the best sight that will force the child to use a sore eye and by that to develop his sight. With the same purpose can appoint a long instillation of drops of atropine in the best eye. Besides, ways of stimulation of an ambliopichny eye by light flashes - so-called photostimulation are developed. Irrespective of the fact which treatment is applied, the most important is timeliness of its beginning, till the moment until the brain of the child learned to suppress or ignore an ambliopichny ("lazy") eye forever.
