Nurses and doctors puncture a patient's skin with a needle in search of a vein around 1 billion times a year in the United States.
In an effort to make this process less painful and time-consuming, Evena Medical has created Eyes-On glasses, which allow the wearer to peer through the skin and see the vascular structure beneath in great detail, the Verge reported.
The Eyes-On unit uses a spectral approach: it pulses with four different kinds of light that are combined into a single composite image, making the veins stand out against the skin.
The image of the veins appears very clearly on a connected tablet, which also shows vital signs.
It is also projected in the patient's field of vision, so that the nurse can see it overlaid on top of the actual body.
After the initial puncture, the Eyes-On glasses can also be used to check for leakage from an IV.
The Eyes-On glasses will go into mass production this April and are expected to retail for around 10,000 dollars.
