I'd think a simple piston arrangement in the side-arm of the glasses would allow for an additional 1-2 diopters adjustment for reading, and also allow for intermediate adjustments for viewing computer displays. A high-tech version could even automatically adjust focus to follow your gaze. Prof Silver's idea also could simplify automatic focus for camera lenses. I wonder whether such spin-offs for richer countries might be able to attract more capital to help fund the development cost for improvements - it's a really great aim to try to get the price to a dollar for for hundreds of millions of people to benefit.
