Actually, there are different types of 3D glasses available in the market. If you want to know what type of glasses you need to use for a certain movie, you can read my blog post here.
If the movie you are watching is in anaglyph format, or the one with red/cyan-red-green outline, you can use a custom-made glasses. It is just made of cellophane. (The one used to wrap Yema or “cheese candy”.)
But just in case you need 3D glasses like the one used in cinema, you can always have it for a very low price. CD-r King have it.
