3D glasses help us experience the excitement that is inherent in movies where we can see images that would appear right in front of us, giving us a real-life encounter. You might see birds fly off the screen in such a realistic way that you would have to duck to avoid being hit by them. The science behind making things reel time to real-time Stereoscopy creates the effect that we see from 3D glasses. Under this, two marginally different images are projected at slightly different angles. Since the human eyes are spaced apart, it means that each eye sees things from different angles and perspectives. To see 3D images, you will have to wear 3D glasses or else those images will appear fuzzy and off balance.
