Switching of a contact lens shaped display. The contact lens is still transparent but is able to modulate the transmitted light using LCD technology. Direct applications could be medical, as an artificial iris, or cosmetic, as an iris with tunable color, or it just could serve as a gimmick. The dollar sign is a reference to the many cartoons featuring people/figures with dollars in their eyes :)

When worn, the image would only be visible to bystanders, since the eye cannot focus on objects in such a close proximity. Research is currently being performed to solve the focusing problem and to see whether an embedded contact lens display that can be seen by the lens wearer is feasible.

All work was performed in the Centre for Microsystems Technology, Ghent University, Belgium.

Additional comment:

Dear All,

This video was originally made to demonstrate the state of our technology to other partners, while also being a test to use new media channels as a promotional tool. If I had known it would go semi-viral, I would of course have payed more attention to it. So, to clear some things out:

1. The music choice is controversial, but to avoid licensing problems I used the music of a friend. Probably there were better choices but, as with all art, it does remain a subjective issue.
2. The dollar sign is a reference to cartoon figures, not to my potential wealth or greed. I am a scientist/engineer at first, not a VC.
3. I do not own a professional camera nor have a well-lit studio, but most quality was lost during editing and conversion. If you want to help out, please feel free to do so.

As for the scientific comments, I try to be as clear as possible to what the technology really stands for. Seeing the emotions it stirs up, I do know I should keep on pursuing this research.

All the best,
