As you know, people with age problems with vision – presbyopia, have to wear glasses with multifocal lenses or use a few points. Israeli startup Deep Optics is creating glasses that adapt to any vision.
However, they can be called glasses by convention. In fact, this is a complex electronic device, where instead of the usual lenses – liquid crystal multifocal lenses, changing depending on how the light is refracted at the moment of passing through them an electric current . In the frame there are special sensors that track the eye when they try to adjust the focal length within a fraction of a second.
The theme of liquid crystal glasses is not new. In 2012, a range of emPower glasses was introduced, where you had to press the button to sharpen the focus. Deep Optics went further, creating a technology that mimics natural vision. This required a lens that changes its optical power without changing its appearance. The result was achieved thanks to liquid crystal technology.
Optical sensors located in the frame, constantly monitor the position of the pupil, when a person looks at an object. The processing unit at this time calculates the optimal focal length for each eye, and then sends an electrical signal to the liquid crystal lens, which forms a clear image. If the glasses are discharged or turned off, the lenses are automatically locked in their original position.
