If you have a habit of losing expensive sunglasses, the innovators at Tzukuri may have the product for you — shades that send an alert to your iPhone if you leave them behind.
The glasses have a small Bluetooth low-energy chip in the temple of the frame. When paired, the app sends an alert if you get more than 16 feet from the glasses. If you don’t cancel the alert (such as if you intentionally left your glasses behind), you will continue to get alerts.
The app also triggers a loud ring on your iPhone if you leave it behind while wearing your glasses.
Tzukuri plans to offer six styles of glasses. The pre-order price is $250, and $350 after they come out in December.
