Retro 3D glasses used to view 3D images and videos on TV aren't used too much anymore. They are being replaced by newer technology glasses.
However, the symbolism of them is still in.
I seen that Panasonic lens, wish they made a really nice one for my 5D Mark II, there's just the Loreo 3D Lens in a Cap which from what I can tell doesn't have very good quality glass @ http://www.loreo.com/pages/products/loreo_3dcap.html
