I’d put this article to one side and have now got around to looking through it. Have a read and see what you think. I’m not a Luddite so who knows, maybe this technology will be used in the future:

The days of switching between reading and prescription glasses are numbered.

Researcher have designed a pair of smart glasses that automatically adjust to what the person is seeing.

The ‘adaptive eyeglasses’ use liquid-based lenses and sensors to let wearer’s see both nearby and faraway objects, without ever having to swap frames.

Researcher have designed a pair of smart glasses that automatically adjust to what the person is seeing. The ‘adaptive eyeglasses’ use liquid-based lenses and sensors to let wearers see both nearby and faraway objects, without having to swap frames.

The early prototype was unveiled by a team at the University of Utah, which foresees the device putting an end to people having to switch between glasses and change prescriptions they are.

‘Most people who get reading glasses have to put them on and take them off all the time,’ says Mastrangelo, who also is a professor for USTAR, the Utah Science Technology and Research economic development initiative.

‘You don’t have to do that anymore. You put these on, and it’s always clear.’

Mastrangelo and his colleague Nazmul Hasan, a doctoral student, designed the special lenses with rubbery membranes made of glycerin, a thick colorless liquid found in soap and skin care products.

There are three actuators on each of the lenses that push the membranes back and forth – similar to a piston in a vehicle.

This process is the key to these smart glasses, as it adjusts the focal length between the lens and the eye.

‘The focal length of the glasses depends on the shape of the lens, so to change the optical power we actually have to change the membrane shape,’ Mastrangelo says.
