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 decoding visual perception and cognition, we’ve developed our first-of-its-kind lens: ZEISS ClearMind with NeurOptix technology provides extremely clear vision and is scientifically proven to help reduce the 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 proves: Blurred vision increases the cognitive load.

Based on the understanding how a person’s vision and mind is connected, ZEISS conducted original research in collaboration with the University of Tübingen to explore whether or not the blur in eyeglass lenses affects the 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 the cognitive load.

The first of its kind.

ZEISS ClearMind are the first ZEISS lenses built on the scientific finding that vision clarity can alleviate mental effort 
– impacting how people see AND feel.

Clear vision where it matters most.

The ZEISS NeurOptix technology in ClearMind lenses considers neuroscience effects by mapping people’s visual behaviour 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 minimise the cognitive load.

ZEISS ClearMind wearers noticed the difference:

  • 96% of wearers confirm that they perceived extremely clear vision.3
  • 76% of wearers say that the lenses increased their ability to concentrate on tasks.3
  • 85% of wearers confirm 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 optimised to provide comfortable and clear vision.

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

The optimised hybrid lens design in digital lenses and progressives features soft blur zones toward the edges and an extra large intermediate zone for smooth transitions in all distances and 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 optimisation to create the unique design fingerprint for ZEISS ClearMind lenses.

Maps real eye behaviour.

ZEISS NeurOptix technology is built on how people use their eyes everyday. Our researchers analysed 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 behaviour and lens wear positioning applied into a mathematical model, ZEISS NeurOptix technology determines the precise locations on the lens necessary to replicate people’s authentic eye behaviour.

Links blur zones to the cognitive load.

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

By considering noticeable blur at far, intermediate and near distance, ZEISS NeurOptix technology identifies the zones where blur unnecessarily increases the 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 lenses geometry in varifocals can cause blur as their lens power progressively increases towards the near zone, leading to peripheral blur and a negative impact on the intermediate zone, requiring the brain to compensate.
While ZEISS Thin Optics technology has long balanced excellent optics and aesthetics, some residual errors remained. Now, with ZEISS NeurOptix technology, lens geometry of ZEISS ClearMind lenses is optimised by considering 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.

A positive mean power error for oblique gaze directions through the lens periphery remains resulting in a focus in front of the retina.

The result: clarity beyond vision.

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