Exciting news for those enough who are 40+ and spend too much time in front of a computer screen: a Finnish startup called IXI is promising to end the era of clunky bifocals and the 'head-tilt' struggle of progressive lenses, replacing them with a pair of glasses that focus as naturally as the human eye using a combination of infrared eye tracking and liquid crystal-transparent indium tin oxide glasses

Clunky bifocals?

Vs the battery, camera, and focusing mechanism these are going to need?

    There is at least graceful degradation:

    When the battery dies, the glasses continue to function as a traditional pair of single-vision specs, ensuring the wearer is never left in the dark or have safety compromised such as when driving or operating machinery.

    Plus “clunky” bifocals have way fewer moving parts and can be made with thin wire frames so they’re lighter.

    I’m sure there might be someone with really bad eyesight for whom these might be useful - like if the near and far prescriptions are too different to be possible, maybe - but this is inferior to the actual solution in almost every way.

    As someone with clunky bifocals, the weight of the frame (even the chunky ones) is absolutely unnoticeable compared to the weight of the lenses. You don't get thin wireframes for the lower weight, you get it because they're less noticeable visually.
