LCD glasses might replace bifocals

The specs use electrodes that can alter the configuration of the LCDs, automatically refocusing based on what the wearer is looking at. There are, however, a couple of downsides. Other researchers scoff that the lenses would end up being too heavy and thick (and the prototype pictured here does look kind of goofy). The other downside: if the batteries give out, you’re left with plain glass.
