Belief and common practice are very difficult to overcome, even in the face of strong evidence to the contrary.
Bleeding a patient was still fairly commonplace in the late 19th century. Traditional medicine probably killed a few US presidents. [Interestingly, leeches are now used to improve blood flow to re-attached appendages; cool stuff.] Eugenics was scientific consensus in the early/mid 20th century. In the 1950’s MD’s were doing commercials touting the medical benefits of cigarettes. How many scientists did the church attempt to execute for challenging the status-quo?
Whenever you hear “scientific consensus,” run for the hills. Science is HARD and must be subjected to decades upon decades of intense adversarial scrutiny before truly becoming valid. Lots of bad science remains unchallenged because vested interests protect the status-quo. That’s one reason it might be best for @jakey to maintain a low profile until inertia changes the eyeball paradigm.
It’s only when a large enough portion of the population sees the commonly accepted wisdom as a horses arse that the profession will begin to pivot. Then, suddenly, “new” research will appear showing how one can improve vision. They will follow, not lead. Until that time an array of vested interests will align to squash this endeavor like a bug.
