Some car tyres can adapt their size according to the terrain. Flexible walls mean flats can be easily converted.
But eyewear that automatically adjusts focus between near and distant objects? Sounds unlikely, but it’s exactly the product a startup from Japan has recently developed together with a design firm.
Before first use, consumers adjust the diopter for both integrated lenses via a dial to bring objects one metre away into focus.
After that, the glasses adjust focus automatically, with a sensor measuring the distance to the viewed object with instant effect. After ten hours of use, the electronic eyewear can be fully recharged within three hours.
And with this special nano-film, it might even be possible to see at night.Â
