Researchers have begun developing more lifelike 3-D displays that might address the problems, but they're years or even decades from being available to the masses. That isn't deterring the entertainment industry, which is aware of the problem yet charging ahead with plans to create more movies and TV shows in 3-D. A handful of satellite and cable channels are already carrying 3-D programming; ESPN just announced its 3-D network will begin broadcasting 24 hours a day next month.
Yet there are already signs that consumers may not be as excited about 3-D as the entertainment and electronics industries are. People went to the theater less, but spent more. Those models cost more than regular ones and require glasses, just like in theaters. Research into how today's 3-D screens affect viewers is only in its early stages. There have been no large-scale scientific studies.
A study of South Koreans watching 3-D screens close up found that 3-D caused more eyestrain than 2-D. The research prompted the Korean government to recommend that viewers take a break of up to 15 minutes after an hour of 3-D viewing.
But that study was based on glasses with red and green lenses rather than the ones used in theaters and with TVs. Based on an unscientific, online survey, the American Optometric Association estimates that 25 percent of Americans have experienced headaches, blurred vision, nausea or similar problems when viewing 3-D. TV makers do their own testing, but don't publish results. Samsung warns on its Australian website that its 3-D TVs can cause "motion sickness, perceptual after effects, disorientation, eye strain, and decreased postural stability.
Nintendo Co. That simulates the way objects that are at different distances in real life appear in slightly different places in each eye's field of view. Of course, the quality of the movies increases, and as well does the quality of cinema equipment.
Now the quality is often higher than Avatar had, but significant decrease in problems may take about years more. Right now looking for a good 3D quality you need to choose high budget movies and properly equipped cinema halls.
Wish you fewer headaches! Vatolin also referenced a French poll that asked movie-goers to report how they felt after watching a 3D movie. According to Vatolin, everyone who watched a 3D movie felt discomfort at least once. Headaches caused by the reordering of left and right views are reactions to the wrong scene coming to both eyes at the same time. This is what has to occur in order for our brains to produce a stereo effect. Vatolin hopes this research can be used practically to cut down on the number of headaches that follow the release of a 3D movie.

Among them, one of the most painful and happily, one of the rarest to be seen blunder is reordering of the left and the right views of the 3D video, that may sometimes happen even in the most professional production.
And that is far from the only disadvantage of contemporary 3D-movies. As the main achievement of his team, Dmitry Vatolin names a creation of 'metrics' - programs allowing to track such errors, minimizing the time of 3D movies technical control. With the help of these metrics the research team scanned the present Blu-ray productions and compiled statistics of the main problems. In particular, 65 scenes with the left-right view swap were found in 23 different movies.
Some problems were found even in such top ranking movies as Avatar, The Chronicles of Narnia, Stalingrad etc.
A lot of various errors were detected in horror movies, Vatolin tells, which can be explained with their relatively low budgets.
