Are Invisibility Materials Real?

A type of material called Quantum Stealth bends light around an object to
make it almost invisible.

Invisibility materials essentially are real, and Canadian camouflage
company HyperStealth Biotechnology has invented a material known as Quantum
Stealth that is claimed to make its wearers invisible to the human eye. The
company did not reveal all of the details of how it was able to accomplish
this technology, but it is known that the material bends the light spectrum
around the object it covers, which makes the object seem to be invisible.
Invisibility materials are mainly being developed for use in military
defense, but Quantum Stealth is more likely to be first implemented for
covering large objects, such as buildings or tanks, rather than being used
for soldiers' uniforms.
