As what we can notice today, almost all popular films and movies has a 3D version. For example, we have a standard film version of “The Pirates of the Caribbean: On Stranger’s Tide” and also a 3D version which is “The Pirates of the Caribbean: On Stranger’s Tide in 3D”. You will notice that the title of most movies have the suffix “in 3D”.

Not just on cinemas but also at home. 3D technology has been equipped with the DVDs and Blu-Rays copies of those films (also called as stereoscopic). I once saw a Shrek movie on DVD in 3D. Most of them come with some 3D glasses to be used by the viewer. But what If you don’t have 3D glasses for your “downloaded” 3D movie?
But some people are still asking about that. What type of 3D glasses should you use to watch 3D movies and films? Or, how to know what type of it should be used?
Actually, the type of 3D glasses to be used will depend of the type of 3D technology which is in the 3D movie you are watching. If you see a red and blue overlay on the movie, then “red/cyan 3D glasses” should be used. If it’s overlaid with color red and green then use a red/green 3D glass. On the other hand, cinemas around the world uses polarized 3D glasses to project anaglyphs.
