UK-based Invisibility Shield Co. has developed a real working invisibility shield that you can actually buy, and it does not involve any kind of magic whatsoever. That’s right, it is all pure science, or to be more specific, a precision engineered lens array that directs much of the light reflected from the subject away from the observer, transmitting it sideways across the face of the shield to the left and right.
Since the lenses in this array are aligned vertically, the oriented strip of light reflected by the standing/crouching subject is diffused when spread out horizontally when passing through the back of the shield. When you’re viewing this phenomenon, the background light is effectively smeared horizontally across the front face of the shield, over the area where the subject would normally be observed. How much will one of these cost you? Well, the company is crowd funding the project, and a full-sized shield is priced at $394 USD for backers. More Information here.

The shields perform at their absolute best against uniform backgrounds such as foliage, grass, rendered walls, sand, sky and asphalt. Backgrounds with defined horizontal lines work really well too and these can be natural features such as the horizon or man made features like walls, rails or painted lines,” said the company.
