From Sciam (via Boing Boing), comes news of an ocular implant designed to act as a telephoto system and correct macular regeneration. It doesn’t seem like a huge leap from this little series of lenses implanted in the pupil, to the same sort of thing being used for cosmetic enhancement purposes.
Researchers in Laval and Florida have been developing thin lenses made of polymers and glass that react to electric currents and change their focal length. The range is currently 60cm-infinity — not quite good enough for human optics (I like being able to see stuff within 60cm, personally) but certainly useful for cameras and other optical applications, and certainly a step in the right direction. When we are able to focus accurately using a single fixed lens and no moving parts that’s one fewer mechanical failure to worry about.
