Medical Glasses Let Nurses See Patients’ Veins Through Their Skin

Medical Glasses Let Nurses See Patients’ Veins Through Their Skin

Eyes-On Glasses help give doctors and medical staff the power of x-ray vision.

Technology has been moving steadily in to the operating room, helping doctors and nurses better perform their duties. For example, some surgeons have recently begun using Google Glass to assist with surgical procedures, either by providing a useful overlay of information or by recording the event for later analysis or training. But what if there was a device that allowed your doctor to actually see through your skin without a single incision or x-ray? Imagine how useful it would be for doctors or nurses to be able to intuitively see through the body in real-time, able to react on-the-fly to changes within your body.


Evena Medical has recently unveiled a pair of glasses that can ‘see through’ skin, and make it easier for doctors and nurses to find the veins in patient’s arms. It’s not always easy to find the right vein for an intravenous drip, since the target vessels are sometimes hidden below the skin; often it can take multiple attempts, causing much discomfort of the patient. The Eyes-On 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.


Eyes-On Glasses can also transmit the images viewed to remote locations via Bluetooth, Wi-Fi and 3G. Combined with the glasses’ two-way audio conferencing capability and built-in storage for photos and videos, the technology could also open up training possibilities and faster communication. Image processing and power are supplied by a separate microprocessor, that is worn on a belt and hard-wired to the glasses.

Evena’s device also uses Epson’s Moverio “smart glasses” technology, which allows the wearer to view overlays of virtual content over objects in the real world. Anna Jen, the director of new ventures and new products for Epson America stated:

It’s extremely gratifying that one of the first healthcare solution concepts featuring Epson’s Moverio smart glasses technology is one that improves both patient comfort and nursing efficiency


The first product is targeted at hospitals, but Evena is also working on a head-mounted display for use by the U.S. Army. The product is also being adopted by paramedics and EMTs to start IVs in patients quickly and permit them to connect with physicians at the receiving hospital. Eyes-On Glasses should be commercially available to medical clients as of the first quarter of next year, and will improve not only the efficiency of doctors and nurses, but also the comfort of patients.
