3D Contact Lenses

There are two ways for this idea to be baked so I shall halfbake them here.

First the simple way. Two contact lenses that have a polarized film on them that are each polarized to a different specific angle. They would be near full eye size with just enough lense to go past your iris so you can line up the black and red dots that calibrate the polarizing qualities of the lenses. Red dot for right eye.

(A short rundown, polarized light not matching the polarized angle of the lenses will be filtered out, thus the blurry effect when you take off your 3D glasses in a theatre.)

The more complicated way. Sandwiched liquid crystals in a lense, flip when current is running through them, effectively cutting out most of the light. The red and black dots now more than just for allignment purposes are also IR sensors and minute solar cells. When the correct signal is given off with the picture taken from the angle of one particular eye, the contact lense of the other eye is shut off. Such IR signals can be bounced off a movie screen. Sterioscopic movie cameras are baked this would just allow for a difference in the ordering of the frames in the movie.

In either case, the contact lenses you bring yourself that are equipped with 3D capabilities will be cleaner and less scratched than the ones you borrow from the theatres. Plus, they can be perscription lenses. A further benefit is that they allow for 3D happenings anywhere outside a movie theatre, wherever the right conditions would occur.
