    I make masks and costumes.I have a camera with a broken usb connection but other than not being able to take pictures off of it it works fine. I want to use the lens and viewer as part of a mask to allow the wearer to see even though the eyes are not in a normal position.

    My eyes really started to hurt the last time I went to the cinema (to watch Avatar 3D), and I think it was something to do with the glasses. Can you do anything to stop it? It is spoiling the film for me.
    Dont say watch it in 2D!
