The concept of electronic glasses with diopters that can switch between everyday and reading modes has been around for a long time - but its technical implementation is still lagging behind. However, given the controversial situation with the segment of "smart glasses" as a whole, this is not surprising. However, the latest news says that the Japanese company TouchFocus is ready to bring a complete product of this type to the market.
The most famous and promising technology for electronic adaptive glasses was the development of PixelOptics. In it, in the thickness of the glass, controllable liquid crystal elements were placed, which, on command from the outside, could change their configuration and thereby affect the focal length of the lenses. It is enough to press a small button on the bow and the system will switch itself to the desired mode. However, at that time, in 2011, it was not possible to create a finished product.
However, the engineers at TouchFocus have managed to cure their colleagues' legacy of "childhood illnesses." In any case, the adaptive TouchFocus glasses are already working, although they consume a lot of energy. This happens only when switching to reading mode, which lasts up to 10 hours on a single charge. And it itself takes 4 hours and requires a USB connection. In addition, while it is impossible to adjust the glasses to the eyes of a particular person, there are only two generalized modes.
But the TouchFocus glasses have a stylish look, "lightness" and more than 20 frame options. They cost $ 2, 200 excluding taxes and are already on sale in Japan.
