The moment your reactions are as sharp as your vision.

ZEISS DriveSafe Lenses for safe and reliable driving.

Safer and more relaxed driving – even in the rain and at night.

Many people feel insecure, uncomfortable and stressed when driving, especially in difficult light and weather conditions, such as rain and mist, and at dusk or night. On average, 83% of spectacle lens wearers* drive. Driving can be a real challenge for everybody – no matter how long the distance, and good vision is vital for safety.

Understanding your needs

In market research studies with consumers, we identified the three most common visual challenges when driving:

  • Poor visibility in low-light conditions such as rain, dusk or at night
  • Glare from oncoming cars at night and dazzle from wet roads
  • Difficulty in refocusing when the eyes switch between the road and dashboard.

ZEISS DriveSafe Lenses – an everyday lens optimised for 80% of spectacle wearers who drive.

With ZEISS DriveSafe Lenses, ZEISS is introducing a new lens product category for daily use. It is specifically designed to meet the visual needs of wearers who want to feel safer and more comfortable when driving with their everyday lenses. ZEISS DriveSafe Lenses are available in both single vision and progressive lens designs.

Strong benefits

One pair of spectacles for everyday use and safer driving:

  • Without DuraVision® DriveSafe
  • With DuraVision® DriveSafe
  • Accurate vision of the road, dashboard, rear-view mirror and side mirrors

ZEISS has developed an everyday lens solution consisting of three elements to make driving safer and more comfortable.

    • Luminance Design® Technology takes into account the pupil size in low-light conditions
    • ZEISS DuraVision DriveSafe coating reduces perceived glare up to 64%
    • The design of ZEISS DriveSafe Lenses incorporates a mid-distance zone that is 43% larger for easier focus when switching between dashboard and mirrors. It also has a far-distance visual zone that is up to 14% larger for a wider view of the road.

High patient satisfaction

To verify that ZEISS DriveSafe Lenses fully meet patient expectations, ZEISS conducted real-life wearer trials.

Wearers are very satisfied with ZEISS DriveSafe Lenses*

Better vision in low-light conditions.

Luminance Design® Technology by ZEISS.

The challenge

The pupil reacts to light intensity from its surroundings, specifically the light that directly strikes the eye. In daylight conditions, the pupil diameter is small, whereas it is large at night. In low-light, so-called mesopic conditions, i.e. twilight, rainfall, gloomy days or night driving, the pupil diameter is in-between small and large. Spacial perception, as well as distance calculation, becomes more difficult for the driver.

After intensive research in the field of mesopic vision*, the rationale for the development of Luminance Design® Technology was identified and verified during wearer trials. In a nutshell: there is bright light (photopic vision), no light (scotopic vision) and in-between low light (mesopic vision). In mesopic conditions, the light intensity, and thus the pupil size changes: a challenge for visual performance.

ZEISS solution

ZEISS developed the new Luminance Design® Technology (LDT), which takes into account different light conditions and pupil sizes to improve the lens design for natural vision at all times. LDT incorporates the pupil size for driving in mesopic conditions and optimises the lens design accordingly: the adapted pupil sizes used in the optimisation algorithms are 5.0 mm in single vision lenses and 4.3 mm in progressive lenses.

As a result, wearers have better vision in low-light conditions.

Bright light = photopic vision with small pupil
Large depth of focus, relaxed space perception

No light (darkness) = scotopic vision with large pupil
Small depth of focus

Low light = mesopic vision with varying pupil size
Challenging conditions due to variation in depth of focus

Reduced glare at night.

ZEISS DuraVision® DriveSafe Coating.

The challenge

Glare describes the difficulty of seeing in bright light, such as direct sunlight or artificial light. Especially when driving at night, the high luminance from car headlights with Xenon or LED technology is disturbing. Glare can be a risk, as it reduces the visibility of objects and sensitivity of the eye to contrast.

Advised by the automotive lighting experts at L-LAB* who provided state-of-the-art lighting equipment, ZEISS vision science researchers carried out glare experiments. These formed the basis of internal studies** using different coating simulations. The blue light spectrum of car headlights (in particular in the 400–450 nm range) using Xenon H.I.D. (High Intensity Discharge) or LED technology produces a glare effect perceived by drivers.

ZEISS solution

DuraVision® DriveSafe Coating partially reflects these wavelengths, which reduces perceived glare up to 64% compared to premium AR coatings.

  • Without DuraVision® DriveSafe
  • With DuraVision® DriveSafe
  • Reduced light-induced irritation such as dazzle and reflection
  • Reduced light-induced irritation such as dazzle and reflection

Accurate vision of the road, dashboard and mirrors.

ZEISS DriveSafe Lenses design.

The challenge

Driving demands a high level of attention from drivers. Most of the time they need a broad view of the road in order to evaluate traffic conditions. The situation becomes challenging, especially for progressive lens wearers, when switching their focus between the road, dashboard and mirrors. That is when dynamic vision becomes essential.

In an eye tracking study with FKFS* we identified the visual field needs of drivers:
• 97% of the recorded time they watch the road
• 2% of the recorded time they look at the dashboard
• 1% of the recorded time they switch focus between the mirrors.

ZEISS solution

To make it easier for progressive lens wearers to quickly refocus between the road, dashboard and mirrors, ZEISS developed the new DriveSafe Progressive Lenses with optimised distance and intermediate viewing zones, reducing the need for horizontal head movement.

  • Dynamic vision for fast refocusing from the road to the dashboard and mirrors
  • Near viewing zone ideally suited to daily activities.
  • Up to 43% larger** mid-distance zone for easier focus when switching between dashboard and mirrors. And up to 14% larger** far-distance visual zone for a wider view of the road.
  • ZEISS DriveSafe Progressive and Single Vision Lenses for clearer traffic evaluation;
  • ideally suited to everyday situations.
