Electronically Tuneable Lense and Glasses

I first saw talk about electronically tuneable glasses in 2012.  The company involved appears to have given up.  ( check my work ).  But it is too attractive of a field of work to be left alone.   It is suggested electronically tuned lenses may be used for lense replacements in cataract surgery.
