Old Norm
Standardised and simplified model of the average human eye used for the production of standard lenses.
From precise eye measurement to true precision vision
For our B.I.G. EXACT® lenses, 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 lets spectacle wearers benefit from the sharpest vision for every angle and every gaze, no matter where they look.

Why Biometric Intelligent Glasses?
The key to understanding the breakthrough technology behind Biometric Intelligent Glasses starts with recognising that you don’t actually see with your eyes – you see with your brain.
Our vision consists of focus and peripheral vision
Our vision relies on two subsystems—focus vision and peripheral vision—which work together with the brain. Peripheral vision helps us navigate our surroundings and detect motion. When the brain picks up on a point of interest, our focus vision moves there to give the brain more detailed visual information, which then determines the next action.
Our eyes move up to 250,000 times a day
The continuous movement of the eyes requires that the lenses provide the right support to the wearer to have a harmonious interplay of focus and peripheral vision. This constant dynamic state of our vision underscores the importance of choosing lenses that address visual sensitivity and provide the right support for your brain.
B.I.G. EXACT® makes a big difference to life
With B.I.G. EXACT® ophthalmic lenses from Rodenstock, the full dynamics of daily life can be experienced again. B.I.G. EXACT® lenses based on DNEye® technology enable an unrestricted, dynamic and natural visual experience, in harmony with the brain.
A Swiss survey of 283 customers, 90% of whom already wore glasses, shows the enormous success of B.I.G. EXACT®. It demonstrated that the use of an exact biometric eye model to produce customised lenses contributes significantly to improving the visual experience.

NEW: B.I.G. EXACT® Sensitive
The world’s first spectacle lenses optimised for individual visual sensitivity and biometry
With B.I.G. EXACT® Sensitive, We have reached a new evolutionary stage. We discovered that visual sensitivity is highly individual and linked it to the individual eyes’ biometry. We used that to further develop our state-of-the-art biometric lens calculations and design lenses that are optimised precisely for each individual, marking the next evolution in B.I.G. VISION®.
