There's been a number of threads on the pros and cons and caveats of vision therapy; we can help you track them down if you're having trouble finding them.

Standard care is once a week with the specialist (usually in office but ours was actually done over Skype), with at-home daily exercises in between sessions. If your provider is recommending something dramatically different than this, or claiming to fix anything other than convergence insufficiency (and maybe, possibly, accommodative insufficiency) get very cautious.
