Make the object invisible?

In real world invisibility came from a trick of light using a glass. You see an object because of light that we see in our eyes. Cloaking the object or making the object invisible involves bending the light to hit our eyes on that object so we can see whats behind that object but not the object itself.

The researches from University of Rochester in the New York have found a way around that. So the object it can be invisible to the viewers. Its the first in the eyes that you can cloak or make the object invisible and they've done it using but nothing 4 standard lenses that you can see and buy in the market or you can find in any lab. The key to make the object invisible by cloaking it is in the setup. It has a mathematical calculation on how far is the lenses to make the object hidden to the eye of the viewers.

As long as you're looking to the first lens, anything that will moving about 15 degrees on the center of the cloaking or invisibility point will remain hidden.

This cloaking or invisibility setup is not  ready for night time sneaking around.
