What are eye therapy exercises that help strabismus?

Depends: Certain strabismus types can be helped with pencil push ups, theoretically, trying to keep the eyes in alignment (look at pencil as you move it away & near). If amblyopia present (lazy eye), patching is needed if a young child.

None: There really are no good eye exercises for strabismus, except for convergence insufficiency.

None: Only glasses and/or surgery can fix it. Convergence insufficiency can be helped a little with vision training.
