Despite what TV and the movies might have us believe, getting a needle into a vein isn't always a straightforward procedure. It can sometimes take multiple attempts, much to the discomfort of the patient. Now, however, Evena Medical's new Eyes-On Glasses reportedly let nurses see patients' veins in real time, right through their skin.
The glasses can be worn over existing eyewear, and incorporate "multi-spectral 3D imaging" (multiple spectra of projected light) to make veins show up when viewed via the glasses' dual cameras. Users see the patient's skin as it really is through the glasses' clear lens, but with an image of the veins as processed by the cameras overlaid on top.
