Few days back Samsung published a note warning people for the dangers of 3D movies. In their note they have warned pregnant women, elder people and many other kinds of people should not watch 3D movies for more than specific time. According to them people can become sick. The problem here is they are not explaining what they mean by sick and how it will happen by watching 3D movies. Bill Nye , the famous American scientist and his eye care group explains why some people will be unwell while watching 3D movies.
According to him 30% of the total population is suffering from ‘Marginal Binocular Vision’ which means that your eyes are not working together as they should be and if they are not in total coordination then you will not get proper stereoscopic 3D effect while watching 3D movies.

To save yourself from that problem you need to take out 3D glasses in between or close one eye and then close the second eye for a moment. You can change the angle at what you are watching the movie.
