As an optometrist i denounce all pseudosciences - they lack scientific evidence, clinical relevance and most importantly can mislead the public into believing a full health check can be obtained from looking at the iris. This not only causes potential serious harm but also undermines those health professionals who undergo years of extensive academic training. All medical/surgical treatments undergo extensive clinical trials and require rigourous scientific proof. In the event of a misdiagnosis on whatever the “iridologist” finds, are they still accountable? do they get charged with misconduct/negligence? what are the limits of their competence? Who regulates them? Whilst I do not doubt that those who feel they have benefitted from such means, i cannot help but to conclude that iridology is nonsense - people should be encouraged to seek medical attention/advice first and foremost. I still find it incomprehensible that people still look to pseudoscience despite the lack of evidence that it has any basis whatsoever (apart from coincidence) and putting thier health at serious risk.

P.S. I applaud the author of this site - great, simple explanations and videos, perfect for students! Makes learning enjoyable.
