Until today. Introducing the beta version of AdBlock Freedom: augmented reality eyewear that detects and removes ads from the world in realtime. 

Here's how it works: when powered off, AdBlock Freedom functions as sunglasses. Slide a discreet switch on the frame, and AdBlock Freedom begins scanning your view for objects that it recognizes as ads. Any detected ad gets a "smudge" overlay to blend it into its surroundings.
