 While wave upon wave of smartglasses and face-based wearables crash on the shores of CES, traditional glasses really haven't changed much over the hundreds of years we've been using them. The last innovation, arguably, was progressive multifocals that blended near and farsighted lenses — and that was back in the 1950s. It makes sense that autofocusing glasses maker IXI thinks it's time to modernize glasses.
After recently announcing a 22-gram (0.7-ounce) prototype frame, the startup is here in Las Vegas to show off working prototypes of its lenses, a key component of its autofocus glasses, which could be a game-changer.
IXI's glasses are designed for age-related farsightedness, a condition that affects many, if not most people over 45. They combine cameraless eye tracking with liquid crystal lenses that automatically activate when the glasses detect the user's focus shifting. This means that, instead of having two separate prescriptions, as in multifocal or bifocal lenses, IXI's lenses automatically switch between each prescription. Crucially — like most modern smartglasses — the frames themselves are lightweight and look like just another pair of normal glasses.

With a row of prototype frames and lenses laid out in front of him, CEO and co-founder Niko Eiden explained the technology, which can be separated into two parts. First, the IXI glasses track the movement of your eyes using a system of LEDs and photodiodes, dotted around the edges of where the lenses sit. The LEDs bounce invisible i

 If you've ever bought a bag of spinach only to come home and realize you already had a bag of spinach, you may appreciate this fridge. I had a chance to check out the GE Profile Smart Fridge with Kitchen Assistant at CES and was surprised to find I kinda wanted one. To be perfectly honest, most attempts I've seen at the show to "stick some AI in it" are at best amusing but usually completely unnecessary.
Here, though, the AI has a purpose. After seeing how the autofill water dispenser worked, I asked the GE Appliance reps how easy it was to change the fridge's water filter. Jason May, a GE Appliances product management executive, walked up to the fridge's (appropriately sized) touchscreen and said "Hey HQ, where's my water filter?" (HQ is short for SmartHQ, GE Profile's assistant). Then, relying on information it had gathered from this model's user manual, the AI assistant explained exactly where to find it (in the left hand door below the ice maker). It took another rep about two seconds to pop out the filter and, justlikethat, the task was on its way to done.
As for the spinach conundrum, that's handled by a crisper drawer camera, called Fridge Focus. Each time you open the drawers, a built-in camera (that you can physically shutter or turn off in the app) takes a video snapshot of what's left when you're done. So if you're at the store and wondering how much kale you already have, you can take a peek and see.
