Three of these adjustable products are real--spot the fake!
Adlens's liquid-filled lenses are for anyone: Twist a knob on the side of the frames, and adjust the prescription to your eyes.
Snapped a photo, but it came out blurry? No problem: The Lytro camera allows you to adjust the focus after it's taken.
Downsize to one pair of jeans: Pull Lucky's new fabric taut and they're dark blue; crumple and they look acid-washed.
Push a button and the car's exterior changes color, as particles in Nano Energia's paint move to reflect different light.
What's fake: Decades after the '90s Hypercolor fad, some heat-sensitive clothing is still sold. But there are no jeans that are this controllable.
