I think that with the rise of 3D movies everyone should own a pair of 3D glasses for themselves. If you could get money off a 3D movie ticket with your own pair of 3D glasses would you buy them for $25 or so? If not, or in addition to, would you purchase your own pair of 3D glasses if you could switch out the 3D polarized lenses with regular polarized sunglass lenses for $30-35?
