ZEISS DriveSafe - Is ZEISS DriveSafe right for you?
One pair of glasses for everyday use and safer driving. |

Most drivers are exposed to difficult driving conditions
that impact their vision, including driving in rain,
snow or fog, and of course driving at night. For most,
this can be a major source of stress - in fact, over two
thirds of adults report difficulty driving in these
challenging visual conditions. Now there’s ZEISS
DriveSafe, an all-day lens and coating solution designed
for patients who need the most help with vision while
driving. ZEISS DriveSafe’s unique technology addresses
the most stressful visual challenges drivers face today.

ZEISS DriveSafe is available in both single vision
and progressive lens types. |

 Is
it hard to see objects quickly while driving in
low light conditions such as rain, twilight, or
night?
• Luminance Design®
Technology by ZEISS calculates the lens with the
optimal pupil size in low-light conditions |
|
 |
| |
|
|
The challenge - Better vision in low
light conditions.
For many drivers,
the greatest visual problems come in low light
situations (mesopic conditions like cloudy/rainy
days and twilight). Eyeglasses have never been
designed to account for the size of the pupil in
these conditions. As a result, space perception
and distance calculation can be
difficult when driving.
ZEISS conducted
intensive research into mesopic vision in
developing Luminance Design Technology.*
Standard lenses are designed using single-ray
tracing, which does not account for pupil size.
This can result in a lens that does not offer
optimal clarity, when the pupil size
is larger in low light conditions.
ZEISS solution
DriveSafe
lenses address this problem with Luminance
Design Technology (LDT). LDT incorporates the
pupil size for driving in mesopic conditions and
optimizes the lens design accordingly. As a
result, wearers have better vision all day,
in low light conditions. |

Are
you bothered by glare from oncoming headlights?
• ZEISS DuraVision DriveSafe Coating is
preferred by patients for headlight glare
reduction by more than 2 to 1. |
|
 |
| |
|
|
The challenge - Reduced glare at night.
Glare describes the difficulty of seeing in
bright light, such as direct sunlight or
artificial light. Market research and scientific
evidence both indicate that perceived glare in
traffic is linked inspecialto LED and Xenon
HID light sources as used in modern car lighting
technology. Intense glare can be a risk, as it
reduces the visibility of objects and
sensitivity of the eye to contrast. Glare also
can be subjectively perceived as discomfort and
irritation.
ZEISS vision science
researchers carried out glare experiments. These
formed the basis of internal studies* using
different coating simulations. Scientific
evidence shows that the blueish, high-energy
part of the visible spectrum (inspecialin
the 440–470 nm range) using LED or Xenon H.I.D.
(High Intensity Discharge) technology is linked
to a glare effect perceived by drivers.
ZEISS solution
DuraVision
DriveSafe coating reduces glare by reflecting
the most harmful wavelengths from Xenon and LED
headlights. ZEISS DriveSafe is preferred by
patients for headlight glare reduction by more
than 2 to 1.

Do
your current eyeglasses make it difficult to
scan the road, mirrors, and dashboard?
•
ZEISS DriveSafe Lens Design incorporates up to
43% larger mid-distance zone for easier focus
switching between dashboard and mirror and up
to 14% larger far-distance vision zone for a
wider view of the road. |

The challenge
Driving
demands a high level of attention. Drivers need
a wide, clear view of the road in order to
evaluate traffic conditions, but they also need
to shift rapidly from the road to the dashboard
and mirrors. This can be challenging
for progressive lens wearers.
ZEISS
conducted an eye-tracking study with automotive
research institute FKFS** at Germany’s
University of Stuttgart. This study precisely
mapped the actual visual behavior of drivers to
determine what areas of vision were needed the
most.
ZEISS solution
Using this data, ZEISS designed the DriveSafe
Progressive with optimized 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 vision suitable
for all day wear
Up to 43% larger***
mid-distance zone for easier focus switching
between dashboard and mirrors. And up to 14%
larger** far-distance vision zone for a wider
view of the road. |

* Compared to premium ZEISS coatings. With DuraVision DriveSafe 64% less test drivers reported issues with glare with the new coating than with other premium AR coatings.
** FKFS Research Institute of Automotive
Engineering and Vehicle Engines Stuttgart is an
