I would be curious to know if anyone here who suffers from these issues finds my startup's software [1] to be helpful. We launched (on HN, as it happens) as a speed-reading tool, but we've heard from many people with binocular vision difficulties, including convergence insufficiency, amblyopia and presbyopia, that our approach makes reading easier.
Obviously this isn't a training tool like the ones mentioned in the article, but I'd be curious if it eases reading for folks who are affected by these issues. Also, if there are any vision professionals here, I'd love to hear expert opinions too.
