It's not always easy for nurses to find the right vein for an intravenous drip -- the target vessels are sometimes hidden below the skin. Evena Medical's new Eyes-On smart glasses may make those injections a little easier. The Moverio-based eyewear overlays a 3D blood vessel map on the patient, helping the nurse insert even a tricky IV line on the first try. It can also tap into a hospital's medical records and share imagery with doctors in remote locations. There's no word on just which hospitals will use Eyes-On when it ships in the first quarter of 2014, but don't be surprised if it makes your hospital stay a little more bearable in the near future. Check out a video promo for the glasses after the break.
