1. Better Vision in low light conditions for safer and more comfortable driving
2. Reduced glare at night from oncoming cars and street lights
3. 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.
1. Luminance Design® Technology takes into account the pupil size in low-light conditions
2. ZEISS DuraVision DriveSafe coating reduces perceived glare up to 64%
3. The design of ZEISS DriveSafe Lenses incorporates a mid-distance zone that is 43% larger for easier focus when switching
Better vision in low-light conditions. LuminanceDesign® 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.
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.
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.
ZEISS solution
DuraVision® DriveSafe Coating partially reflects these wavelengths, which reduces perceived glare up to 64% compared to
premium AR coatings.
Accurate vision of the road, dashboard and mirrors. ZEISSDriveSafe 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.
ZEISS solution
To make it easier for progressive lens wearers toquickly refocus between the road, dashboard andmirrors, ZEISS developed the new DriveSafeProgressive Lenses with optimised distance andintermediate viewing zones, reducing the need forhorizontal head movement.
• Dynamic vision for fast refocusing from the road tothe dashboard and mirrors
• Near viewing zone ideally suited to daily activities.
