Smart-eyewear, often called smart glasses, are a wearable that you wear like glasses and the lens(es) act like a screen where it displays some sort of heads-up-display. For example, it may give you a view of a map with directions to your destination, the weather, facts about the world around you or many other things. The most well known smart glasses is probably Google Glass, although competitors are starting to emerge with cheaper versions such as GlassUp, EmoPulse, ION Smart Glasses, Samsung Smart Glasses, or Vuzix M100. Some require a phone to be connected to but most can operate standalone. Computer World went as far to dub 2014 the "Year of Smart Glasses" with all of the new models announced this year.
