What's my line?

I was fascinated to see in the results of the survey of GPs (Optician, February 17) that under the heading 'GPs' awareness of functions optometrists currently perform', no less than 99 per cent were aware that we 'test sight for spectacles'.

I would be just as fascinated to find out what the other 1 per cent think we do.
