Evanas 'X Ray Glasses' Can See Through Skin (VIDEO)

For years X-Ray Specs were a staple product featured in the back pages of comic books, designed to lure imaginative schoolboys into sending 50p to a PO Box in return for the promise of looking at peoples' underwear.

Now it's here - but this time it's real, and useful. Evana's Eyes-On Glasses are a new device designed to be worn by doctors in order to see through your skin.

The specific purpose is to help doctors find veins when giving injections to patients. Apparently up to 40% of the time doctor's miss a patient's vein and need to perform two or more procedures. The new glasses use four kinds of light (not harmful X-rays at all) in order to make an image of the skin that contrasts veins with the rest of your flesh.

With this image - taken by cameras embedded in a pair of wearable glasses made by Epson, and projected onto screens just in front of the eyes - a doctor can more accurately target the vein.

The glasses can also be used to check for leakage from IV tubes, the makers told The Verge.

The glasses will be on sale to medical professionals from April, costing $10,000. Check out the video above for more details.
