A company in Finland say they’ve developed the world’s first glasses that will autofocus whatever you’re looking at. You won’t need brain implants or have to plug them into some kind of wearable computer. In fact, it’s pretty simple tech. Think of a clear, mini LCD screen, like on your TV, sandwiched between plastic lenses. The glasses use a low power sensor that tracks your eyes while they move. Meanwhile, they also emit invisible light pulses into your eye which bounce back letting the lenses measure reflections off the back of your eyes. Then it determines if you’re looking near, far, or somewhere in between. Then it sends electrical signals to the lens to adjust accordingly. Right now, the lag time is a tenth of a second.
If these work, say “Goodbye bifocals!” It’d be goodbye to a lot of kinds of glasses including having reading glasses of different strengths lying all over the house. Or, should I say, hiding all over the house.
The company said these autofocus glasses are still in development with live demos in a few months.
There’s another company out of Berlin that says they have autofocus glasses too. Here’s the video where a guy tried them. They seem janky.
