Researchers at the University of Utah have designed electronic glasses that automatically focus on objects both near and far according to where the user is looking.
Once commercialized, the eyewear could replace reading glasses that are not worn regularly and progressive lenses that require the wearer to look through different zones in the lens depending on the distance of the object.
A smartphone connection with Bluetooth allows users to upload eyeglass prescriptions to the glasses, which are automatically adjusted.
Electronic components on the frames of the glasses surrounding the lenses control membranes on the front and back of the lenses so that focus is achieved depending on what the user is looking at. A meter gauges the distance of the objects and activates the focus within 14 milliseconds.
