Our eyes are as unique to each of us as our fingerprints, so it therefore follows that we need glasses specifically tailored to our personal vision. For that reason, leading global manufacturer of high-quality ophthalmic lenses Rodenstock is constantly working to find the best solution to make the best lenses and glasses through its new corporate philosophy: B.I.G. VISION FOR ALL – Biometric Intelligent Glasses.

The new paradigm shift in individual progressive lenses was first presented at opti 2020, the international trade show for optics & design in Munich, Germany last month before being announced in Thailand recently by Dr. Dietmar Uttenweiler, Rodenstock’s Head of Research & Development and Strategic Marketing Lenses in an event at The Sukhothai, Bangkok.

“B.I.G. VISION FOR ALL – Biometric Intelligent Glasses is the company’s philosophy as well as the product concept, as we believe that every individual should have big vision. That means the best possible vision, with broad and sufficient feeling and sharpest vision for everyone,” said Dr Uttenweiler. “B.I.G. also stands for biometric intelligent glasses. So it’s also a product concept and B.I.G. VISION is now how we describe the relevance of this technology because it’s a completely different and new way of producing spectacle lenses calculated to fit the shape and size of the eye of each individual.”

Rodenstock has been continuously working on the concept for 20 years and all the technological developments the company has made have come together in B.I.G. VISION.

“We started in 2000 when we became the first company to launch individual lenses worldwide meaning that it was possible to measure and to take into account the size of the lens in front of the eye. Then, in 2011, we introduced the EyeLT lens technology, the lens that helps to compensate for effects during near vision. DNEye brought biometrics into play, and with the DNEye Pro which we launched in 2018, we also consider the entire dimension of every individual eye, as it is important to know that eyes differ significantly.”

Nowadays almost all progressive lenses are created using the same static reduced eye model, which has been used as the standard parameter for decades but actually represents just 2 per cent of eyes globally.

Rodenstock is the first manufacturer to measure the individual eye and use thousands of data points to produce glasses integrated with biometric intelligence for the sharpest vision.

Dr. Uttenweiler continued: “Biometric refers to the measurement of human properties. That means we can precisely measure the eye with a device called a DNEye scanner. It not only measures the visual operation but also the anatomical parameters on every individual eye and that forms the basis for our lens calculation. Why intelligent? Because it’s not that easy to use all these biometric data to produce lenses. So this is the knowledge, the science behind what Rodenstock stands for. We can actually use this data to produce lenses that so far, no one else has been able to do. And this is a completely new paradigm shift of how you produce and calculate lenses.”

Rodenstock’s B.I.G. Vision with DNEye Technology delivers a seamless, dynamic and natural experience that works perfectly together with the brain. Using the DNEye Scanner, Rodenstock measures all the eye’s relevant biometric parameters that are necessary to create a unique biometric eye model. This biometric eye model includes eye length, corneal power and thickness, anterior chamber depth, pupil size in photopic and mesopic light conditions, crystalline lens power and vitreous chamber depth. It is for this reason that Rodenstock measures the eye using thousands of data points with the groundbreaking DNEye Scanner, allowing Rodenstock to precisely determine all relevant biometric parameters as well as more refraction error data than anyone else.

B.I.G. Vision delivers up to 40 per cent sharper vision at near and intermediate distances and an 8.5° wider field of sharp vision at near distance. When asked about their experience with Biometric Intelligent Glasses in a Swiss study, users experienced a wide range of benefits to their vision, with 88 per cent of participants noticing greater visual comfort with their DNEye glasses compared to their old glasses, 92 per cent experiencing sharper vision than before, 84 per cent noting better contrast vision and 87 per cent experiencing reduced adaption time.

Dr Uttenweiler said that the technology is far more beneficial for producing lenses, especially progressive lenses as these are the most difficult in terms of calculating and constructing. It is especially useful in meeting the visual demands of people who getting older, as their visual acuity becomes more varied simply because the eye is not as young. Their eyes therefore need more help to perform and that directly translates into the performance of the lenses and the perception when wearing the spectacles.

“However the technology is valid for single vision lenses as well because it’s a new approach to what we do. We measure both the vision and eye anatomy of each individual to calculate the lens. And we do that both for single and progressive lenses.

Rodenstock was founded in 1877. Headquartered in Munich, Germany, it employs around 4,900 people worldwide and is represented through sales offices and distribution partners in more than 85 countries. Rodenstock maintains production plants at 14 locations in 13 countries including Thailand.
