Since bifocals were first invented in the late 18th century, the technology behind them hasn’t changed too drastically. Now an Israel-based start-up is working on a new type of lenses that use smart tech to automatically adjust their focus based on what you’re looking at, MIT Technology Review reports.
The company, called Deep Optics, has spent the past three years developing their Omnifocals. When people wearing the glasses aren’t looking at objects up-close, the lenses default to focusing on objects farther away like a regular pair of glasses. The moment the wearer moves their eyes to look at something closer like a book or a phone screen, sensors built into the frame measure the distance between the pupils and send the data to a mini processor. The processor then uses this information to adjust a special liquid-crystal layer in the lenses so that it refracts light accordingly.
