Here's another interesting case: a progressive lens wearer who drives a lot found that his glasses simply didn't work quite right. In spite of multiple fittings, he was still unhappy with his vision when driving. A ZEISS eye care professional wanted to know why and decided to go for a drive with the customer. The cause of the problem was clear immediately. This eyeglass wearer had reclined his seat so far back that he was almost lying down – thus with this 'normal' progressive lens design he had to look through the near vision or intermediate zones to see into the distance. He was only able to look through the distance range of the lenses by tilting his head in an extremely uncomfortable position. The eye care professional was able to optimize this patient's glasses to accommodate his seated position when driving, providing the patient with comfortable vision.
Truck drivers who wear progressives spend their entire workday on the road and look through their glasses differently than someone driving a car. Truck drivers bend their head slightly forward when looking at the road ahead because of the elevated sitting position, so they are looking through the area on the progressive lens where you typically find the intermediate zone. Thus it is especially helpful to optimize the lens design accordingly.
Did you know that there are ZEISS lenses which have been specially optimized for driving? You can wear DriveSafe lenses for the entire day. They feature a unique design and a special coating which demonstrate their strengths when you're driving: learn more about DriveSafe here.
Progressives for pilots pose another particular challenge because pilots don’t just look down at the instruments on the dashboard like someone driving a car. Depending on the type of airplane, pilots also need to look overhead at their instruments. Ideally they would have a second near zone / intermediate zone in the upper section of the lens.
Many jobs place unique demands on a person's vision, and progressives must rise to these challenges. For comfortable vision, writers or graphic artists require a different design in the near zone than teachers, who often switch their gaze between the near zone and a particular intermediate distance in the classroom, or policemen who require good long-range vision as well as a clear intermediate zone for their daily work.
However, it's all about the fine details if you're a dentist or jeweler. Here a magnifying attachment for your glasses can help.
Many people require improved vision for looking at things up close rather than in the distance. But it's inconvenient for them to continually put on and take off their reading glasses. For these people, the ideal solution is progressive glasses with prescription powers for only near and intermediate vision and none for distance.
Here's what your glasses can do for you when hunting.
Contact lenses are a very good alternative to glasses – yet there are still a few vision solutions that are only possible with good ol' glasses.
The demands being made on our vision have increased phenomenally in recent years. BETTER VISION talks to Laura Rocha about how the new ZEISS Progressive Portfolio takes these challenges into account.
Customized lenses for driving make driving not only more relaxing, but also increase safety significantly. But what do consumers have to bear in mind when buying glasses for driving?
Something everyone thought impossible in the past: progressive lenses that are as individual as their wearers are now the measure of all things.
