I'm in the UK, within 90mins drive of the University of Essex. I suppose it's most likely that this effect won't be widely replicated amongst CH patients, but, as others have alluded to, it seems to warrant some attention. Even if it worked for must a handful of sufferers, that would be better than nothing.
I would absolutely be willing to participate in any study should one be forthcoming. To be honest, I'm keen just to get my hands on some glasses now. Seems like little to lose in giving it a go.
