Adjustable Focus Eyeglasses
The future has finally found eyeglasses – you can now buy glasses that let you adjust the focus with the twist of a knob. Adjust your vision for reading or for distance simply by turning a dial on the glasses – incredible.
A company called Adlens is the major player in this area right now – they sell adjustable glasses starting at under $50. But there are also many competitors starting to make a name for themselves, such as Eyejusters.
