lenses

I wear glasses, but don't own contact lenses. And while this normally doesn't make a difference, staring into the midday sun often leads me to think about switching to contacts simply so I can wear sunglasses.

Well, just as I all but convinced myself to switch, the Institute for Bioengineering and Nanotechnology (IBN) in Singapore goes ahead and makes sunglasses all but useless for contact lens wearers. Behold, the first ever transition contacts.

Imaging an unborn fetus and and spotting a lurking submarine could both become much easier with the world's first acoustic hyperlens. The device manipulates imaging sound waves to provide an eightfold increase in the magnification power of technologies such as ultrasound and sonar.

It's the year 2023 and you're lost in a gigametropolis full of flying cars and robots who have achieved singularity. A guide literally appears before your eyes, giving you enough info about your surroundings to guide you on your way. The computerized contact lenses that Babak Parviz is developing could make this fantasy a reality.

In place of glass lenses that move in order to focus, liquid optics uses a drop of water that changes shape when an electric charge is applied. The system is smaller and cheaper than glass and can supposedly focus faster. The tech recently appeared in the Akkord SnakeCam, a webcam sold in China. We brought one stateside and pitted it against two versions with glass lenses.
