From Pat Scott Vincent
I make use of colour, image and iris patterns in my work, having run a training company for colour and image consultants for over 20 years. I am concerned that people seem unaware that iris patterns can change (10 September, p 26). I have observed some dramatic changes myself and every iridologist has seen irises alter due to changes in health.
Everything I read on this subject fails to mention any precautions that might be taken against such an eventuality and I find this very worrying.
