How interesting are the new focal glasses? – Health

So far, contact lenses or lenses that have a correction for reading and vision have been the best solution to this day. But for a lot of people, this combination just doesn’t work enough. Therefore, two Belgian developers joined forces and designed auto-focus lenses with a separate button for reading.

At about age 45, the first signs of presbyopia or presbyopia appear in many people. Reading a book or your smartphone up close becomes difficult, and reading glasses are a must. But those who are already nearsighted also need a correction to see further away. Progressive lenses, where the two corrections are contained in one lens, are the most common solution to this. But this approach is not without flaws and has limitations for quite a few users. With this system, you can search through different viewing areas, depending on whether you want to focus at a close or far distance. This sometimes distorts the image or limits your field of view, making it difficult to estimate obstructions, for example.

world first

In order to adapt the cover there, Jelle De Smet and Paul Marchal have spent over 5 years working on a completely new technology solution, in collaboration with Imec, Ghent University and Tokai Optecs. The Flemish government also invested in this innovation. This resulted in auto focus lenses, a world first made in our country. These electronically controlled lenses promise to solve the current shortcomings of progressive eyeglasses. “Unlike progressive eyeglasses where the correction of both aberrations is contained in a single lens, AF glasses contain two ultra-precise optical lenses. Between them there is a sensitive layer with a special fluid. This ensures less drift between viewing areas and more viewing comfort.” Paul Marshall explains, Developer and CEO of Morrow, which markets focal lenses.Due to the revolutionary nanotechnology that controls the glasses, they can only be made using 3D printing.

“With ordinary double vision glasses, the difference between the viewing areas is often significant. At the same time, the field of view is limited because you always have to look through a certain visual area for far, medium or near dimensions. Using AF glasses we have identified the differences between corrections, so you get less distortion when switching between viewing areas.You also have a wider, more complete and equally sharp field of view for both far and near.Depth perception also improves, according to our tests.TV can be watched again with these glasses, which is not Often possible with multifocals, because there is no automatic correction of reading glasses at the bottom of the glass as with regular multifocal glasses because people do not use this correction 80% of the time,” explains Paul Marshall.

“In addition, it often creates dangerous situations because it makes it difficult for them to spot obstacles on the ground or when going up stairs, for example. Only at times when it is necessary, such as reading the lowercase letters on the package leaflet or in such an additional correction For reading it comes in handy in some dark situations.We make up for this in these glasses with an innovative button on the right leg of the frame, which is controlled by the battery.With one press of the button, get a clear picture thanks to the built-in technology for increased instant reading for sharp close-up reading. .Depending on usage, the battery should be charged every two to three days. After reading, you can quickly turn this button off again and you won’t be hindered by correcting the reading glasses during your other activities.”

For everyone?

The developers are primarily aimed at people who do not currently receive or receive sufficient assistance with progressive lenses. But not all eye defects qualify. “It is suitable for problems such as astigmatism, but abnormalities that are too large will not work at the moment. To find out if your abnormal eye condition qualifies, we offer a free at-home eye exam by an optometrist without obligation.” Adequate self-assessment test. Focal lenses prices range from 1099 to 1400 euros. In the meantime, development continues and plans are already underway for further development towards smart glasses.

Meanwhile, the field of view is limited because you have to look through a specific visual area each time far, central or close. With focal lenses, we’ve defined the differences between corrections, so you get less distortion when switching between viewing areas, and you also have a wider, fuller, and equally sharp field of view for both far and near. Deep vision also improves, according to our tests. And you can watch TV while sitting on the sofa again with these glasses, which is often not possible with multifocals, because there is no automatic correction for strong reading glasses at the bottom of the glass as with normal multifocal glasses because people do not use this correction 80% Of the time, Paul Marshall explains. “In addition, they often face dangerous situations because, for example, they are less able to detect obstacles on the ground or when going up stairs.

But not all eye abnormalities qualify. “It is suitable for problems such as astigmatism, but very large aberrations are not currently possible. To find out if your eye condition qualifies, we offer a free at-home eye exam by an optometrist.” You can also take a helpful self-assessment test on Morrow’s website .
