Fed up with multifocal glasses or having to switch your glasses for reading, now a US Company has come up with a $100 solution that allows people who struggle with their strength of their glasses to adjust with the turn of a dial.
Launched at CES 2021 the new Voy glasses can change focus from -5 to +2 in a matter of seconds, eliminating the need to carry multiple pairs of specs To adjust the lenses, the wearer can turn the wheel away from the nose for a more negative power, or turn the wheel towards the nose for a more positive power.
The glasses use a technology first developed in the 1960s by Luis Walter Alvarez, a Nobel prize-winning scientist.
It relies on two polycarbonate plates on each side of the glasses, which slide across each other when the wheel is adjusted.
Depending on the position of the plates, the strength of the lenses is adjusted.
The Company claims you can adjust one eye at a time then fine-tune your vision with both eyes open for the most comfortable view.’
