Paper Abstract
We describe and demonstrate a pair of diopter-adjustable eyeglasses aimed to correct presbyopia; the glasses provide a tunable optical power in the whole surface of the lens cell, eliminating the optical distortion typical of bifocal/trifocal or progressive glasses. The wearer can actively control the optical power by a simple sliding gesture on the bridge of the glasses, so that presbyopic vision can be interactively corrected. Results from a preliminary experiment showed that a presbyopia sufferer could clearly observe near and far objects under the assistant accommodation of the glasses. Designing a truly wearable system poses some challenges – none of them theoretical – so the system should be feasible in the near future.
