At first, I thought this could be quite intrusive. I mean, you're putting something in your eye! It's the same discussion as the biometry authentication systems (retina scanning, saliva, etc).

But then I realized: the alternative is to put a piece of hardware under your skin! It will be embeded in you "forever" and can only be removed via surgical procedures...

These contact lens, if ever available, will in fact revolutionize the diabetes scene and may open precedent to new "wearable" technologies targeting health.

Maybe. You need to understand that diabetes equipment is a lot like a Segway - it's interesting and solves a problem but it's expensive and somewhat infeasible.

Many things could contribute to this not being as revolutionary as it sounds. Everything from cost down to accuracy is a concern. Diabetics do like to have hope that this will be the game-changer but they've heard that many times before.
