Lumus DK40, the best smartglasses of CES 2014 (pictures)

LAS VEGAS -- For the best example of a personal head-up display at CES 2014, look no further than the well-made Lumus DK40. The kicker? A prototype to get creative juices flowing for other device makers, it isn't even meant to sell directly to customers.

In the growing field of smartglasses, this one has a familiar frame, but also something unique: prisms striped right on the glass to give you a personal head-up display.

Indicator lights on the bottom of the thicker piece light up the device.

The Lumus prototype here demonstrates one problem facing the industry, that of a heavy, lopsided build. Get more of the story in my hands-on by clicking the link below.
