Contact lenses

There was a piece on our local TV news about a research project at UWO for contact lenses that change colour depending on the BG reading.  see the link at ctv.swo.ca Health & finess file.  An interesting concept but there is no accuracy as yet.

That would be really cool either way...colo(u)r changing contacts would be awesome :) As long as they didn't change the colo(u)r of the things we're seeing
