Sony SmartEyeglass Attach

By offering a module that clips onto any pair of glasses Sony neatly sidesteps the fashion issue and caters for glasses wearers interested in smart eyewear. It’s a single lens display module that adds a tiny color OLED display with a 640 x 400 pixel resolution, and a camera to your glasses.
It’s being pitched as a sports device to begin with. As an example it might help with navigation for runners or tell a golfer what the distance to the next hole is, though it sadly lacks built-in GPS. In fact it has to be tethered to your smartphone via Bluetooth. It is waterproof and it weighs about 40g, but it’s still a prototype right now so there’s no release or pricing information.
