What are Zeiss Drivesafe lenses?
Zeiss DriveSafe Lenses are lenses with a special coating for everyday use. The Lens and coating have a focus on driving conditions. The lenses aim to improve the driving experience for those who wear glasses whilst behind the wheel. Tailored specifically, the lens enhances the vision needs of people who want to feel safer and more comfortable while driving. Drivesafe lenses are available in single vision and a progressive lens type. Zeiss Drivesafe lens Coating reduces glare at night from oncoming cars or street lights. They provide better vision in low-light conditions and ensure an accurate view of the road, dashboard and mirrors. A survery taken by Zeiss revealed 97% were very satisfied whilst driving and using the Drivesafe Lens. 94% were very satisfied whilst doing everyday tasks, like being in the office. The Drivesafe lens is an Opticians award winner.
When driving, the conditions are constantly changing. The morning commute could start bright then turn dull, or the evening drive back could be during sunset. This would mean bright direct sunlight dulling to a darker lighting condition. This will change the size of the pupil. In darker conditions the pupil will be larger and in brighter conditions the pupil will be smaller. Zeiss have improved the lens design for a more natural vision at all times. Zeiss have taken into consideration the changing pupil size and changed algorithms to enhance performance.
In conclusion these changes give the wearer better vision in low-light conditions. This is brilliant for driving as it is less tiring on the eye. It also takes lower concentration levels, at times when the wearer will already be slightly fatigued. Therefore, making the driving experience easier and safer for the wearer in conditions that can be testing or tiring. This allows the wearer to concentrate more after a day at work or in wet and slippery conditions.
When driving, glasses wearers will be all too familiar with the perceived glare created by lights from cars and traffic lights. This glare can be discomforting and distracting. This is a combination that makes driving more difficult and potentially dangerous. Glare can cause headaches and eye fatigue. Both can be uncomfortable at the best of times, let alone whilst driving. Research and Scientific evidence indicate that most glare comes from the LED and Xenon H.I.D lights used on modern cars. The scientific evidence shows the blue high-energy part of the visible light spectrum within the LED and Xenon lights link to the glare effect. The blue part of the wave that pass into the eye doesn’t hit the same part of the eye as the other elements of the light, thus causing the glare.
Drivesafe lenses partially reflect the blue waves, reducing the glare by 64% (compared to other Zeiss premium coatings). This reduces the dazzle and reflections experienced whilst driving, so the road ahead is more visible. Therefore, with reduced glare the eyes are more comfortable and the wearer can asses the road better and safer.
The Drivesafe Lens comes in a single vision and a progressive lens for those who wear transition lenses. When driving the eye flickers between looking at the road, dashboard instruments and between mirrors. In an experiment conducted by Zeiss, they recorded that 97% of the time the driver is looking at the road, 2% at the dashboard and 1% at mirrors. Each of these three variables are at different distances, so a progressive lens wearer will need to use different parts of the lens to see the different distances. This will require extra movement from the neck. On a long journey, the constant head movement may cause potential neck pain or soreness.
To help make the driving experience easier for progressive lens wearers Zeiss have widened the far and intermediate zones. This lessens the amount of horizontal head movement needed by the wearer, making the driving experience less tiring on the neck. In addition, it allows for fast refocusing when moving the eye from the dashboard to the road for example, therefore making the experience safer and clearer. Whilst the far and intermediate zones have seen improvements for driving, Zeiss have also ensured that the near viewing zone is ideally suited for daily routines to make the lens multipurpose, and ensure the wearer only needs the one pair of glasses for driving and all day uses. This irradiates the need for daily glasses and driving glasses.
