Moneo writes: Becoming centres of holistic primary care

It seems to be the norm nowadays for optometry practices to ally themselves with audiology specialists. I note from last week a leading firm of opticians announcing a tie up with the Ida Institute in Denmark to further enhance delivery of hearing care. This symbiotic relationship between eye care and hearing care has grown like topsy in recent years. Why is this the case? And why is it just audiology that seems popular? Is it that optometry and audiology are inextricably linked when it comes to health care, or could it be that it makes sound financial sense? Why is it that optometry does not expand into other areas of primary healthcare?
