Lens designed to reduce cognitive load

Zeiss Vision Care is launching the Zeiss ClearMind portfolio: all-day premium lenses designed for exceptionally clear vision and proven in an in-house study to reduce cognitive load.

Specifically designed for today’s visually demanding, digital-centric lifestyles, Zeiss ClearMind represents a significant advancement for eyecare professionals (ECPs), said Elmarie Pretorius, product/professional services and national sales manager NZ, Zeiss Vision Care Australia & New Zealand. “Our visual world is overloaded and so are our eyes. For the first time, we have demonstrated that lens-induced blur has a measurable impact on cognitive load. When the retinal image is not crisp, the brain compensates, which can lead to cognitive overload and reduced visual comfort. By delivering outstanding clarity and reducing blur, we can positively influence cognitive load and lessen the effort the brain expends to process visual information. This is exactly what we have achieved with Zeiss ClearMind.”

In Zeiss studies, 96% of wearers said they experienced extremely clear vision wearing Zeiss ClearMind lenses, while nine out of 10 also said they experienced less cognitive load in a blind test, compared with a standard Zeiss progressive lens. Eighty-five percent of wearers also said the lenses contributed positively to their overall sense of wellbeing.

How it works

Zeiss NeurOptix is the innovation behind the lower cognitive load. By aligning lens clarity zones to natural eye-movement patterns, the technology applies advanced blur management so that optical errors are reduced and optimised while clear vision zones are increased, the company explained. Applying this technology, commonly existing blur zones within progressive lenses are moved to non-impairing lens areas, providing Zeiss Progressive ClearMind lenses with up to 41% larger zones of clear vision compared with Zeiss SmartLife progressive lenses for near distance. Zeiss said 51% of wearers adapted within one hour, rising to 88% within a few days.

In addition, Zeiss is also upgrading all its coatings to include the Zeiss CleanGuard Technology, which was introduced with Zeiss DuraVision Gold UV in 2025. “This will give ECPs the opportunity to offer premium anti-reflective coatings with improved smudge resistance for easier cleaning,” Pretorius said.

“I’m confident that the Zeiss ClearMind lens portfolio, together with our upgraded coating technologies, will enable ECPs to provide their patients with more relaxed, effortless vision and improved comfort throughout long, digitally intensive and visually dynamic days. For the practice, it establishes a new premium category that goes beyond ‘better optics’ to lenses explicitly engineered for visual performance and comfort under digital stress,” she said.

The Zeiss ClearMind Portfolio includes single vision (for those aged over 18 years), progressive (for the over-45s) and digital (for the over-30s) focal types. The lenses have customisation options, including Zeiss Intelligence Augmented Design, a data-driven technology utilising 12.5 million data points to optimise lenses for age-related visual behaviour, the company said.
