I just received a call from them. It is from Optical Express. They try and persuade you to come for a consultation, by telling you how good it would be to have perfect vision. They have structured questions they ask you, as a strategy to try and persuade you, possibly also by subliminal suggestion. They might try and make you subliminally feel like it’s the right thing to do (to have surgery), but you won’t know why you feel like it’s the right thing, unless you know the tricks of subliminal suggestion. Clever b******s. Don’t be deceived.
