B.I.G. EXACT® Sensitive
The world’s first spectacle lenses optimised for individual visual sensitivity and biometry

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. B.I.G. Vision™ from Rodenstock creates a paradigm shift in progressive lenses by recognising the unique shape and size of each of your eyes. By producing lenses based on your individual eye’s measurements, our glasses are constructed to ensure you enjoy the sharpest possible vision.

With B.I.G. VISION®, Rodenstock developed a biometric eye model that allowed us to produce millions of biometric lenses. These lenses are adapted to the individual biometry of your eyes through precise measurements from our DNEye® Scanner. Now, we're taking biometric individualization even further: We discovered that each person has a unique visual sensitivity. We can use this knowledge to tailor lenses specifically for a person’s visual sensitivity – introducing our newest product B.I.G. EXACT® Sensitive.

Visual sensitivity is a new input we use in the lens calculation. It describes how strongly a person’s visual perception reacts to disruptions in their vision field. An AI algorithm has allowed us to determine individual visual sensitivity from biometry measurements made with our DNEye® Scanner.

​From precise eye measurement to true precision vision with biometric intelligence.

At Rodenstock, we determine the biometrics of the whole eye. This includes its length and several thousand data points in the eye – far beyond industry standards. With the help of these data sets an exact eye model is generated for each individual eye.

​All relevant biometric data flows directly into the lens production process - on this basis, we can calculate a lens that fits each individual person as perfectly as possible. This allows us to determine the center of sharp vision for each individual eye. And spectacle wearers benefit from the sharpest vision for every angle and every gaze, no matter where they look.

To underline the level of biometric precision Biometric Intelligent Glasses (B.I.G.) delivered thanks to exact eye measurements, we now call them: B.I.G. EXACT™.

Providing a B.I.G. VISION FOR ALL with Artificial Intelligence.

By using Artificial Intelligence Rodenstock brings a new level of biometric precision into lens calculation.

Using statistical analysis, we are able to determine new, more precise lens calculations for all of the most important biometric parameters in the eye. and unleash the potential of one of the biggest biometric data sets in the industry.

Rodenstock’s new lens calculation norms allow us to create an approximate biometric model of the eye, using just the standard prescription values delivered to Rodenstock by opticians as input.

With its new artificial intelligence technology, Rodenstock is finally able to make Biometric Intelligent Glasses available to all progressive lens wearers. We call these new lenses: B.I.G. NORM™.

Six steps to the B.I.G. Vision™ experience

Prior to your eye examination with our Optometrists, we use the DNEye® Scanner to determine the dimensions of your eyes.

Your eye parameters are measured to create an exact representation to be used in the manufacturing process of your lenses.

We then send the data to Rodenstock, where patented calculations are used to create a biometric data set.

This data is used to produce a precise biometric model of your eyes.

The models of your eyes are used in the lens calculation which is then transferred to the lens during production.

Just a few days after your initial consultation, you receive your new glasses integrated with biometric intelligence.
