Belgian team develops “LCD” contact-lens display

What a mean trick that headline is. Everyone reading that thinks its going to be an awesome augmented reality enabling HUD, and instead we find out its only a "display" for everyone BUT the wearer.

Isn't there a rule about writing biat switching headlines?

It's the headline of the actual article. I suggest you write a strongly worded letter to the editor explaining the HN submission guidelines.

Probably best send it in triplicate, just to be sure.

It also isn't really inaccurate. The team was Belgian. They developed a contact-lens. The contact-lens uses "LCD" technology and acts as a display.

True... I thought it was going to be a HUD type thing but I blame that on me wanting a HUD and having no interest in using my contact-lens to display things to passers-by.

Maybe it's time to invest in one-way mirrored sunglasses?

I never understood how contact-lens displays were supposed to deliver a focussable image on the retina. Is this doable? Maybe it will require some kind of magic metamaterials or something.

I don't think it's doable with today's technology, that's why laser-based retina projection is what everybody's working on right now. Achieving the same effect with a thin and semitransparent lens would require a lot of engineering to achieve tightly controllable photon angles and I imagine power/data transmission to the lens would also be an issue. Also, personally I would rather put on a pair of glasses than stick a piece of plastic directly into my eye.
