Note — There are 3 groups of people this article is directed to. First are critics who have no real understanding of Iridology, but have negative opinions. Second are Iridologists who have not been exposed to, or are resistant to updated practices in the field. Third are those who understand and practice modern Iridology, but don’t have a historical perspective of this evolution.
The art and science of Iridology has been undergoing an evolution typical of many alternative health assessment and treatment practices. Through continued observation and correlation, understanding of iris signs and their meaning has increased. This progress is correlated to advancements in microscopy, photography, and computer imaging, as well as communication between Iridologists regarding their observations.
Limitations of these factors hampered early Iridologists. Older books relied on reproduction of color drawings. Once photography became available, accuracy of the color pictures remained inadequate for many years. Until very recently, computer-based image capture systems weren’t able to reproduce highly accurate images. High quality slit lamp microscopy of the live iris has mostly been underutilized. Language differences have hampered communication between Iridologists. To this date, many books and research articles in German and Russian remain untranslated into English.
