Can I get contacts that shoot laser beams?

Scientists in Scotland have developed an ultra-thin membrane laser that can be placed on a contact lens and emit a low-intensity green laser beam. The research team says this could have applications as a “wearable security tag where they may complement authentication via an iris scan”. (via)
