Canada Pharmacy Reports the Cons of Watching 3-D Movies

"Avatar," "Hugo" and other 3-D movies thrill many viewers, but also make some feel sick. Young adults and those sitting close to the screen are more likely than older viewers to experience blurred vision, nausea and other symptoms while "immersed" in a 3-D [three-dimensional] film. In times like this, Generic Domperidone will surely help relieve stomach discomfort, nausea, vomiting and reflux encountered while watching 3-D films. 

"3-D movies are only good as long as you're not feeling terrible," said study lead author Shun-Nan Yang, a senior scientist at Pacific University College of Optometry in Forest Grove, Ore. 

Symptoms, which are brief and temporary, are related to visual disturbances and motion sickness. But they can be minimized -- at least if you're watching a 3-D movie at home -- by sitting farther back and gaining a wider viewing angle, Yang said. 

Also, an eye doctor may help you resolve any vision issues, Yang added. 

The most severe problems reported were headaches and nausea, Yang said. Symptoms could increase within 15 minutes after watching the film, he said, although the problems didn't last into the next day. 

Watching movies in 3-D is visually challenging because the eyes must adjust to the fixed closeness of the screen and the seeming distance of the 3-D images, he said. If you're in a movie theater, he said, you may experience fewer symptoms while watching 3-D than viewing the film at home. 

Older viewers were less sickened by 3-D than younger viewers, possibly because they're less sensitive to visual stimulation or the deterioration of their eyes makes it easier to handle the near/far discrepancy, he said. Younger viewers reported more "immersion" in the 3-D movie. 

Yang said it's a mystery why many viewers have visual or physical complaints after watching ordinary movie images on TV. Those people also said they suffered eye problems when they used computer monitors, he said. 

If you're watching a 3-D movie at home, Yang said, you might avoid symptoms by changing where you sit to obtain a different viewing angle or adjusting the brightness of the screen or the lighting in the room. "When you sit closer, you are going to perceive the movie as more real, but you'll have more symptoms," he said. 

One solution for children bothered by watching 3-D movies is to let them take off their 3-D glasses and simply watch the blurred movie, said eye doctor Dr. James Salz, a clinical professor of ophthalmology at the University of Southern California and spokesman for the American Academy of Ophthalmology. 

He's tried that with his own grandchildren, ages 4 to 7. "They don't complain as they seem more comfortable," he said. To buy Domperidone online is good for emergency purposes. 

Three-dimensional space is a geometric 3-parameters model of the physical universe (without considering time) which we are. These three dimensions are commonly called length, width, and depth (or height), although any three directions can be chosen, provided that they do not lie in the same plane. 

In physics and mathematics, a sequence of n numbers can be understood as a location in n-dimensional space. When n = 3, the set of all such locations is called 3-dimensional Euclidean space. It is commonly represented by the symbol. This space is only one example of a great variety of spaces in three dimensions called 3-manifolds.
