The closest we have come is something called meta-materials. These are materials engineered to cause light to refract in the opposite direction found in "normal" materials. Meta-materials can be shaped to cause light to bend around an object, this is called cloaking. Now there has been a very limited demonstration of this ability and there are many technical challenges from this being implemented to make something "invisible". For one thing, the materials work only for very narrow frequency bands so we cna't cover teh entire region of visible light. Another issue is if you are inside the cloak, and all the light that falls on the cloak is bent around it, how do you see out? Light has to come from outside to enter your eye.

Im agreed with earlier answer. also in detail, for viewability light should focus on to your ratina. hen only it can be transfered to brain n we can realise the picture. if you are invisible it means you are transpoerent then no light will focus on ratina how will u see the world. if you are invisible then you must be blind too.
