Clarity for the eyes and mind.

About 80% of all the sensory input we receive comes through our eyes. This makes good eyesight essential for life in our fast-paced, information-packed world. Keeping up with these seemingly endless demands requires our eyes and mind to work hand-in-hand.

Driven by a global breakthrough in neuroscience that is decoding visual perception and cognition, we’ve developed a first-of-its-kind lens: ZEISS ClearMind with NeurOptix technology provides extremely clear vision and is scientifically proven to help reduce perceived cognitive load.2

The science behind ZEISS ClearMind.

How vision works.

With vision being the dominant sense for humans, seeing clearly is essential to unlocking human potential in today’s fast-paced, visually demanding world. At ZEISS we know vision is a complex process that happens also in the brain, not just the eyes.

As light and visual information enter the eye, it is projected onto the retina, where the photoreceptors sit. Signals from the photoreceptors are projected via bipolar and ganglion cells to the lateral geniculate nucleus.

Further information processing (e.g., recognition of shapes, objects, etc.) happens in different areas of the brain, including the working memory – a cognitive system responsible for temporarily holding and processing information needed for complex tasks, such as reasoning, learning and comprehension.

Crisp, clear vision is easy for the mind to process. When vision is blurred, the eyes transmit incomplete information to the brain. This forces the brain to work harder to interpret and fill in the gaps with the missing details, increasing the cognitive load.

ZEISS research shows that blurred vision increases cognitive load.

Based on our understanding of how a person’s vision and mind are connected, ZEISS conducted original research in collaboration with the University of Tübingen to explore whether or not the blur in eyeglass lenses affects cognitive load. Lens blur may increase the effort required for the brain to process visual information.

In an EEG (electroencephalography) study, participants were asked to perform different tasks while their brain activity was monitored. We then introduced lens blur to the tasks and compared their performance and brain responses.

The result: For the first time worldwide, ZEISS demonstrated that lens blur affects cognitive load.

The first of its kind.

ZEISS ClearMind is the first ZEISS Lens built on the scientific finding that vision clarity can reduce perceived cognitive load.

Clear vision where it matters most.

The ZEISS NeurOptix technology in ClearMind lenses take into consideration neuroscientific effects by mapping people’s visual behavior and natural eye movement patterns during frequent everyday tasks.

These insights guide the design of ZEISS ClearMind, ensuring exceptional clarity in lens zones where the brain needs it most, while managing lens-induced blur to minimize perceived cognitive load.

ZEISS ClearMind wearers notice the difference:

  • 96% of wearers report extremely clear vision.3
  • 76% of wearers say that the lenses increase their ability to concentrate on tasks.3
  • 85% of wearers report a positive contribution to their overall feeling of well-being.3

Edge-to-edge brilliance.

Through signature ZEISS technology, the ClearMind lens design is further optimized to provide comfortable and clear vision.

In ZEISS ClearMind Single Vision Lenses, all noticeable blur is considered in the lens optimization, resulting in clear vision from top to bottom.

The optimized hybrid lens design in our digital lenses and progressives features soft blur zones toward the edges and an extra large intermediate zone for smooth transitions at all distances and in all directions.

A breakthrough in optical innovation.

At ZEISS we know vision isn’t just optical, it’s also neural. Our pioneering ZEISS NeurOptix technology considers these neuroscience effects in the lens design optimization to create the unique design fingerprint for ZEISS ClearMind Lenses.

Maps real eye behavior.

ZEISS NeurOptix technology is built on how people use their eyes everyday. Our researchers analyzed which lens zones are used most frequently, how long eyes stay in certain areas, and how tasks shift between objects at different distances.

Pinpoints clear vision zones.

Through extensive ZEISS expertise in ocular anatomy, eye movement dynamics, visual behavior and lens wear positioning applied to a mathematical model, ZEISS NeurOptix technology determines the precise locations on the lens necessary to replicate people’s authentic eye behavior.

Links blur zones to perceived cognitive load.

Some lens-induced blur goes unnoticed, but in some areas it can trigger perceived cognitive load.

By considering noticeable blur at far, intermediate and near distance, ZEISS NeurOptix technology identifies the zones where blur unnecessarily increases perceived cognitive load and where lens clarity adds the largest cognitive benefit, enabling effortless vision.

Advanced blur management in ZEISS NeurOptix technology.

Counteract the cognitive load from lens-induced blur.

Traditional lens geometry in varifocals can cause blur, since their lens power progressively increases towards the near zone. This leads to peripheral blur and a negative impact on the intermediate zone, requiring the brain to compensate.
Although ZEISS Thin Optics technology has long balanced excellent optics with aesthetics, some imperfections remained. Now, with ZEISS NeurOptix technology, the geometry of ZEISS ClearMind lenses is optimized to factor in individual prescription effects using a geometrical control algorithm – enabling smooth transitions and effortless focus.

A negative mean power error for oblique gaze directions through the lens periphery remains, resulting in a focus behind the retina.

The result: clarity beyond vision.

The lens design optimizations introduced by ZEISS NeurOptix technology help deliver sharp and clear vision – which can also improve mental clarity.
In fact, 91% of ZEISS ClearMind wearers experience less perceived cognitive load.11 This promotes easier focus and better concentration – enhancing their overall sense of well-being.3
