A poll of 1,100 health experts – including GPs, doctors and optometrists – found 37 per cent per cent are not aware of Charles Bonnet syndrome (CBS) which can cause vivid, and sometimes frightening, visual hallucinations for those who have lost 60 per cent or more of their sight.
Of those who are aware of it, a tenth admit they have a very limited understanding and 51 per cent would like to learn more.
