My son is suffering from amblyopia.

I do Google, And I found almost same like my son suffering from. Amblyopia, also known as lazy eye, is reduced vision in an eye that results from misalignment of the eyes. A need for glasses, or disruption of light passing through the eye. If recognized early (preschool years), amblyopia generally responds well to treatment. If recognized later (after 9-10 years of age), amblyopia is much more difficult to treat and the child may have permanent vision loss. Signs and symptoms to watch for include misaligned eyes, squinting one eye, bumping into objects or other signs of poor depth perception, head tilting, and double vision. Amblyopia therapy can include glasses, patching, eye drops, and sometimes surgery. Please suggest me what I have to do among the options? I thanks a lot to Google who help me describe my problems, untill now I was unaware how to say my problems. Please help me doctors.. My son is 7 yrs old, local doctors suggested spectacles, Which is using since from 4 yrs,
