Evena Eyes-On vein viewer review

One of the sad facts of getting old, is that you’ll need more medical attention. However, while there are plenty of medications that can be given to help you age respectfully, finding a vein to inject can be quite difficult, as vascularity decreases. Fortunately it looks like Evena might have solved the problem of finding a good vein for medical professionals, it’s called the Eyes-On.


The Eyes-On is a head mounted display and camera system, that gives nurses and doctors the ability to see a patient’s veins and arteries in real time, through the skin, giving them a much better idea of thickness, placement and susceptibility to blow out. This is achieved though multiple spectrums of light being analysed by the cameras built into the Eyes-On. It’s able to look at infrared, as well as visible light, with the image sent to either the augmented display on the glasses themselves, or wirelessly to a display nearby, letting the patient or other medical staff observe what’s going on as well.

The big selling point of this system is that it’s totally hands free. While Evena has offered this sort of imaging system before, it’s only now with the Eyes-On that it’s made it available without the need for plenty of wires or some sort of cart system.

This means that only one member of staff is required at a time and patients need only be stuck with a needle once, to achieve the desired result.

The power for the device comes from a belt system, featuring both battery and a small computer system. It’s lightweight, but hidden out of the way so as not to interrupt what the medical professional is doing.


Unfortunately Evena is only a provider for medical institutions, so this isn’t a piece of technology that’s available to end users as of yet. However it would be interesting to see if it had any applications in the fitness field.


Since it’s a professional, medical device, drawbacks in this case are a little different than a more consumer focused product. As interesting as the technology is, it does look a little silly. Older patients, the kind that would benefit the most from this sort of imaging, are not particularly likely to trust it. Similarly, due to the cost of needing a separate headset and computer system for each medical staff member, I’m not sure hospitals would be willing to dish out for too many until the technology is proven effective.

Bottom line

As interesting as the technology is, time will tell if it sees much usage in this form, or if it gets bundled into something like Google glass to provide more functionality over all.
