Yeah, I know, this sounds like made up craziness. But wait.

Tzukuri has implanted a solar-powered 3mm BLE chip into the frame of each pair of sunglasses, which then allows you to pair your sunglasses to your iPhone (no mention of Android, yet).

Why is this useful, you might ask? Well, similar in concept to Tile, Tzukuri hopes to help you solve a particularly irksome problem when it comes to eye wear – buying a fashionable, expensive pair of shades only to lose them when you are out and about.

Once your phone is paired to your shades, your phone will notify you if they ever become separated by a distance of more than 16 feet- indicating that you might have left your phone behind. Or, conversely, if you happen to be wearing your sunglasses but walking away from your cell phone, their app will pick up on this movement and ring loudly, reminding you to retrieve your phone.

I think this sounds useful and, I suspect, a feature that expensive sunglasses will standardize on in the future. Or you can just get the $15 sunglasses off the rack at the drug store.
