Beynes in London?

[Jabout]

I've been told I'm Green White colour weak, (despite the fact I've never had any trouble playing cricket or lawn tennis!).

I would like to find out if I can pass the Beyne Lantern test, without having to do a full medical in Gatwick.

Does anyone know anywhere in London or if necessary the U.K.
where I can do the Beyne privately?

Hell if necessary I'll even take the wife for a weekend trip to Europe - (if it's the only way to do the test)

Thanks for any responses.
