3d contact lenses

Simple on/off contact lenses

Contact lenses that, like certain IR 3d glasses, simply darken and lighten, in order to facilitate three-dimensional displays. This would be useful in an urban environment, and a simple, near-future step towards augmented reality. As a bonus, or as a selling point for Nvidia, or whomever, the lenses could double as polarized sunglasses....

       Actually in the near future (or the present, if you can afford it) you won't need special eyewear/headgear to use a 3-D display. See the links I just posted for further research.   

       That said, I would still like to have contact lenses that can turn into sunglasses on command. Just not for 3-D displays... the alternate polarization method used in movie theaters necessarily makes the picture half as bright, which is no good.

How so?

       This would make a cool Hollywood hacking premise: hack the sync-signal for the contact lenses so both go dark at the same time for subliminal durations allowing stuff to happen 'in plain sight' of someone.
