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



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.
And if you forget to charge your bifocals they still work the next day.
