What fantastical childhood toy could soon become reality for medical professionals?

A new device developed by Evena called Eyes-On glasses, shown above, allow the user to see through human skin, revealing the vascular structure beneath (what kiddos used to think X-Ray Spex could do).

The glasses do not actually use X-Rays, but rather emit four different types of light, each of which picks up different details. The device then combines the four images gathered from the light emissions and creates a composite image, which is what the user sees. They are expected to retail for about $10,000.
