Our unique philosophy

B.I.G. VISION™ FOR ALL

At Rodenstock, we recognize people as individuals, with eyes of different shapes and sizes. That's why at Rodenstock, we use thousands of data points to measure and determine the parameters of the eye and use this data to produce the lenses customised according to the biometric parameters of each individual eye. This has made us the lens experts we are today.
Our ambition that we at Rodenstock have had since the launch of our B.I.G. VISION™ philosophy:
To create a B.I.G. VISION™ FOR ALL.

Because biometric precision is a matter of chance for most lens manufacturers.
Today, most progressive lens manufacturers produce lenses using a standard eye model. In 98% of these cases, the biometric parameters of a standard eye model deviate from the true values of the individual eye. This means lenses are not tailored precisely to the needs of the individual´s eyes.

Click on one of the three persons to see in the video how the real values of eye parameters deviate from a reduced standard eye model. These eye parameters can be determined by measuring the eyes with the DNEye® Scanner.

The B.I.G. VISION™ Story

We wanted to be more precise.

At Rodenstock, we determine the biometrics of the whole eye – far beyond industry standards. These data points are integrated directly into the lens. The result: the world’s most precise lenses - with the sharpest vision for every angle and every gaze.

Learn all about Rodenstock's journey to biometric precision.

Today, most lenses are manufactured using a standard vision test with just four standard prescription values as input for the lens calculation process.
At Rodenstock, we are constantly striving to pioneer how precisely progressive lenses can be crafted.

The B.I.G. VISION™ Story
The today and tomorrow of biometric lenses

The result of our journey to biometric precision.

Biometic Intelligent Glasses based on DNEye® technology become B.I.G. EXACT™.

With Biometric Intelligent Glasses based on an exact biometric eye model powered by Rodenstock’s unique DNEye® technology, Rodenstock creates a paradigm shift in progressive lenses by taking into account the unique shape and size of each eye.

B.I.G. NORM™: Artificial intelligence and the new norm of lens calculation.

Rodenstock’s new AI technology raises the level of precision in progressive lens manufacturing, even when only standard prescription values are available for lens calculation. This means all progressive lens wearers can now experience the benefits of B.I.G. – Biometric Intelligent Glasses.
