Actually, many/most 3d films now don't use polarised lenses. The glasses in the Dolby3d system have filters that block certain specific wavelengths of light. The image seen by each eye is actually subtly different in terms of colour, but it's close enough that humans can't detect the difference.

This means that the glasses are more expensive than polarised ones, but the projectors are much cheaper, which is why the cinemas really love it.

So could this actually work at home with no extra equipment?(besides the glasses of course)
