3ds for your eyes.

Like the Nintendo 3ds it can create fake virtual images projected from a card to on a screen called AR or augmented reality. Google is as we now speak developing glasses that pretty much projects the internet. Futurama's eye phone has almost come to life only. The thing is you look a bit ridiculous since others can't see what you see so it will look like you dancing around like a maniac.

The bad things is that it is (like the 3ds) mostly can be used for a short period of time before it can cause major eye damage " The glasses are not being designed to be worn constantly — although Google engineers expect some users will wear them a lot — but will be more like smartphones, used when needed, with the lenses serving as a kind of see-through computer monitor."
