The Mysterious Retina

In the fascinating world of the eye, two components matter most: the iris, which surrounds the pupil, and the retina at the back of the eye.

The Iris: The Curtain of the Eye

The iris is the colored layer of pigment around the pupil, visible at the front of the eye. It determines our eye color and works like the aperture of a camera: it regulates how much light enters the eye, narrowing in bright light and widening in the dark. It can hold pigments of different colors and is widely known through iris photography, which is very popular at the moment. Here you will find a page we have dedicated to the iris.[2]

The Retina: The Sensory Network

The retina houses the rods and cones some may remember from biology class: specialized nerve cells that pass light impulses on to our brain via the optic nerve. It lies hidden at the back of the eye and can only be seen with a special camera – which is why it remains relatively unknown.[1]

A Beautiful Pattern That Belongs to You Alone

The retina is extraordinarily complex in structure and function. Three of its most important features explain why it fascinates us so deeply.

01 Macula

Where Sharp Vision Happens

The macula is the central area of the retina. It is responsible for sharp vision and allows us to perceive detail – to read text or recognize faces.[3]

02 Optic Nerve

The Wildest Region

Here the nerve fibers converge to form the optic nerve, which carries the signals to the brain. At the same point, the arteries enter and the veins exit. Around the optic nerve, the vascular pattern is at its most expressive – and usually at its most interesting for our designs.[4]

03 Blind Spot

What the Brain Fills In

Where the optic nerve exits the eye there are no light-sensitive cells – this creates a blind spot. The brain fills in this area unnoticed, so we perceive no gap in our field of vision.[5]

Why We Use Your Retina for Jewelry

«How does anyone come up with such an idea?» I hear this question almost every day – and it is more than justified. The answer needs a little background: I came to Switzerland from Austria in 2000 to earn a doctorate in neurobiology. For hours on end I analyzed nerve cells under the microscope, fascinated by the complexity of our nervous system.

After my years in the pharmaceutical industry, I trained as a goldsmith and, together with my wife, built up the atelier «kleine Rheinperle» on Basel’s Rheinsprung. Soon I had discovered two new passions: creative jewelry design and entrepreneurship.

In Search of a Personal, Aesthetic Signature

As we focused more strongly on wedding rings, we quickly realized: mass-produced goods and standard designs were not for us. However unique our handcrafted rings were – personal enough they were not. I wanted to create something worn by one single person, something with a direct, unmistakable meaning.

Above all, we were searching for our own wedding rings and were disappointed by the creativity of the jewelry industry – everything looked much the same. For the most emotionally important piece of jewelry in our lives, one we hoped to wear on our fingers for six decades, an impersonal mass product made no sense – we wanted something personal.

An engraved name was not enough. Fingerprints always had something forensic about them for me – deeply unromantic. Palm lines, the sound waves of a voice: intriguing ideas, but they did not meet my aesthetic standards. What I had in mind was a signature both personal and beautiful.

Then my biological side spoke up – and suddenly it was clear what we needed: the retina. It is ultra-personal, as unique as a fingerprint, and yet far more beautiful. At first glance it recalls the roots or branches of a tree, with crossings that look like embraces, sometimes even like hearts.

Not Just Little Veins

To some, vessels on a wedding ring seemed strange at first. But these are not the red veins that appear in the eye after a long night out – those sit at the front, on the conjunctiva, and have nothing to do with the retina. You have to look, quite literally, a little deeper: the uniqueness and beauty of this hidden pattern carry a symbolic meaning that goes far beyond «veins somewhere in the body».

What Science Sees in the Retina

The retina is the only nerve tissue in the body that can be observed directly. In medicine it is therefore known as the «window into the body» – and current research shows just how much this window reveals.

Artificial intelligence can determine biological sex from a single retinal photograph almost without error – experienced ophthalmologists perform no better than chance at the same task.[10] Algorithms estimate age to within about three years, read blood pressure from the fine course of the vessels, and assess cardiovascular risk about as accurately as classic tests that require blood samples.[10] Researchers at the University of Lausanne have also shown that when a retina appears «older» than its owner, the statistical risk of numerous diseases rises – the retina reflects how we live.[11] For a brief look at this research, watch this video on YouTube.

Every retina, then, carries far more within it than the eye can see. We read something different in it than medicine does: not data, but an image – an intertwined network of roots that exists exactly once. The template for a piece of jewelry that belongs to you alone.

The RETINA® atelier in Basel’s old town

From the First Image to a World Premiere

For the first real retinal images, I contacted a Basel specialist in 2016 – he replied to my email immediately with the words «a breathtakingly beautiful idea!» – and we photographed my wife’s retinas and mine that very day.

In 2019 I presented the concept at 15 trade shows worldwide: Zurich, Bern, Lucerne, Paris, London, Edinburgh, even Abu Dhabi. Symbolic jewelry like this had never been seen before – the power of the idea fascinated almost everyone.

Two people holding each other’s gaze – the magic of eye contact

The Magic of Eye Contact

Our eyes are not only a marvel of nature; they are perhaps the organ that connects us most directly with the world around us. With a single glance we share fear, joy, love, wonder – without words, without a common language. Eye contact is far more powerful than many people think.

A social experiment demonstrated this strikingly: around 45 000 people in more than 90 cities worldwide held eye contact with a stranger for one minute each. Many reported a sense of special connection afterwards – after just one minute.[8]

The «eye contact exercise» also became famous through a performance by the artist Marina Abramović: in «The Artist Is Present», she sat opposite strangers at the Museum of Modern Art in New York for months in 2010, looking into their eyes.[7]

Frequently Asked Questions About the Retina and the RETINA® Concept

What is the retina?

The retina is the light-sensitive layer of nerve tissue at the back of the eye. Its rods and cones convert light into nerve signals that travel to the brain via the optic nerve. The beautiful lines visible in retinal images are blood vessels. The retina can only be seen with a special camera, which is why it remains relatively unknown.

What is the difference between the iris and the retina?

The iris is the colored aperture at the front of the eye; it determines eye color and regulates, like a camera aperture, how much light enters. The retina sits at the back of the eye and converts that light into nerve signals. The two are often confused – for our jewelry we use the pattern of the retina, not the iris.

Why does RETINA® use the retina for jewelry?

Because the retinal pattern is ultra-personal and as unique as a fingerprint – but far more beautiful. At first glance it recalls the roots or branches of a tree, with crossings that can look like embraces or hearts. It sits precisely at the threshold between our visible outer world and our inner world: the window to the soul.

Is a RETINA® piece a biometric or medical product?

No. We understand the retina as a personal, hidden and aesthetic signature, not as a biometric identifier or medical feature. An expressive section of the pattern is artistically abstracted. It serves neither identification, diagnosis nor security, but symbolism and beauty.

What can artificial intelligence read in a retinal image?

An astonishing amount: studies show that AI can determine biological sex from a single retinal photograph almost without error, estimate age to within about three years, and read indications of blood pressure and cardiovascular health from the fine course of the vessels. That is why research regards the retina as a «window into the body». For us, this underlines one thing above all: how much depth and individuality this hidden pattern holds.

Can anything about my health be read from a RETINA® piece?

No. Your piece carries an artistic, goldsmith-crafted abstraction of your retinal pattern – not a diagnostic image. Medical analyses require the original retinal photograph at full resolution. We treat it with strict confidentiality and never pass it on.

What happens to my retinal image? How is my privacy protected?

We treat your retinal image as an artwork and a secret at once: it is used exclusively to design your piece of jewelry, stored securely and never shared with third parties. Invoices and certificates contain no biometric data either. On request we delete your image once your piece is completed – though most clients ask us to keep it for possible future commissions.

Does the retinal pattern change over a lifetime?

The basic structure of the blood vessels forms before birth and remains essentially stable for life. That is precisely what makes the pattern such an enduring personal mark. For medical details, please consult recognized sources such as Wikipedia or ophthalmological institutions.

Do identical twins have the same retinal pattern?

No. Even identical twins, who look the same on the outside, have different retinal vessels. The pattern is unique even where the genome is identical.

What is the macula?

The macula is the central area of the retina and is responsible for sharp vision. It allows us to perceive detail – to read text or recognize faces.

What is the optic nerve, and why is this region so interesting for the pattern?

At the optic nerve, the nerve fibers of the retina converge and carry the signals to the brain. In this region the arteries enter and the veins exit. That is why the area around the optic nerve is the «wildest» zone – and usually the most interesting one for the pattern we use in jewelry.

What is the blind spot?

Where the optic nerve exits the eye there are no light-sensitive cells – this creates a «blind spot». The brain fills in this area unnoticed, so we perceive no gap in our field of vision.

Are the lines in a retinal image the same red veins you see after a long night out?

No. The red veins visible in the eye after a long night sit at the front, on the conjunctiva, and have nothing to do with the retina. The vessels of the retina lie deep at the back of the eye and form the fine, tree-like pattern we use in our designs.

Is the RetinaScan dangerous or unpleasant?

No. A special camera photographs the retinal pattern without contact and completely safely, much like an examination at the ophthalmologist. It is not a procedure, just a photograph.

How long does the RetinaScan take?

About one minute. The scan is available in Basel or with a partner from our worldwide network.

Where did the idea of using the retina for jewelry come from?

Founder Stefan Wacha came to Switzerland from Austria in 2000 for a doctorate in neurobiology and was fascinated by the complexity of the nervous system. While building up the goldsmith atelier together with his wife, he searched for a personal yet aesthetic signature for wedding rings. Fingerprints felt forensic, sound waves out of place – until his biological side delivered the answer: the retina.

What does eye contact have to do with the RETINA® concept?

In most cultures, the eye is considered the window to the soul. Eye contact creates closeness and connection within moments – as social experiments with many thousands of people worldwide have shown. A piece of jewelry that carries this very pattern sits, symbolically, at the threshold between outside and inside.

Who is Marina Abramović, and what does she have to do with this?

Marina Abramović is a performance artist. In «The Artist Is Present», she sat opposite strangers at the Museum of Modern Art in New York for months in 2010, holding their gaze. The work made strikingly visible how powerful and moving wordless eye contact can be.

Can I have the RetinaScan done from abroad?

Yes. The scan is available with a partner from our worldwide network, the consultation takes place by video, and the finished piece is shipped worldwide.

Where do I go from here?
