Iridology - Keeping A Close Eye on Your Health

Most people will be familiar with the expression that eyes are the “windows to your soul,” meaning that looking into a person’s eyes allows you a glimpse into their emotions and the way they’re feeling at that time. But our eyes can also tell us a lot about our physical well being too.

The science of iridology (the study of the iris of the eye), although still seen as an “alternative” medical practice, is not a modern, “new-age” development. It has actually been around for centuries, with the oldest discovered records showing a form of iridology in use in ancient China as far back as 3 000 years ago.

Iridology research began in earnest in 1670 when Dr. Philippus Meyens published a paper describing the eyes of his patients when they became sick or injured. By observing the eye, Dr Meyens could accurately identify areas in need of attention long before the manifestation of any physical symptoms.

The first known map of the iris was developed in the early 1800s by a Hungarian doctor, Ignatz von Pezcely. Ignatz became fascinated with the iris as a child, after capturing an injured owl in his garden. He noticed that there was a black line in one of its eyes at the time that he captured it, but after the leg had healed, the line turned white. This simple observation sparked a lifetime of interest in the iris as an indicator of the body’s health.

Today, iridology is widely taught and practiced in many countries around the world.

How Does Iridology Work?

The irises of our eyes are as unique as our fingerprints – no two patterns of fibres and colours are alike. The markings in our irises can give doctors and health practitioners a detailed picture of the overall health of our bodies, showing, for example, areas where toxins have accumulated, or which organs are over or under active. Iridology is also able to indicate the overall the condition of our nerves, blood and lymph systems, as well as how good – or bad – our circulation is.

A complete iris analysis can show whether you have a strong or weak constitution. The density of the fibres in the iris, together with its structures, colours, patterns and degrees of darkness and light can give a trained iridologist a good idea of the general health of your body, as well as highlighting any chemical or nutritional imbalances.

It’s important to understand that iridology cannot pinpoint or identify specific diseases, but instead provides crucial information about our body tissues – the state of which can often give advance warning of tendencies towards illness or ill-health before symptoms appear.

For example, iridology won’t locate gallstones, but will indicate the inflammation and toxic conditions that create the perfect environment for them to grow.
