Smith Optics launched its Lowdown Focus smart glasses in Italy in January, and the distribution is being expanded to the rest of Europe this month. Like in the U.S., orders can only be made through the company's website, with a program that is being made available in five languages. More than 1,900 pairs have been sold in the U.S. since the product was launched last September. The sunglasses help the wearer to fine-tune his or her own concentration through a mindfulness program that uses brain-sensing technology from Muse. The brain wave data are collected through sensors inside the nose pieces and the temples. They are fed into an app and converted into sounds like wave crashing on the beach when the mind is not focused, gradually settling down and switching to a birdsong when a more focused mindset is reached.
