Three-Dimensional £¨3D£© movies have been becoming more and more popular in recent years£®It seems 3D TV sets may be going into family households in the near future£®While new digital 3D technology has made the experience more comfortable for many, for some with eye problems, long 3D viewing may result in an aching head, doctors say£®

         "There are a lot of people walking around with very minor eye problems, which under normal situations, the brain deals with naturally," said Dr Michael Rosenberg, an ophthalmologist £¨ÑÛ¿Æҽʦ£© in Chicago£®He said in a 3D movie, these people face a completely new sensory experience£®"That translates into greater mental effort, making it easier to get a headache," Rosenberg told Reuters£®

         In normal vision, each eye sees things at a slightly different angle£®"When that gets processed in the brain, that creates the perception £¨¸Ð¾õ£© of depth," said Dr Deborah Friedman, an ophthalmologist in New York£®The images people see in three dimensions in the movies are not calibrated £¨Ð£×¼µÄ£© in the same way that their eyes and brain are£®"If your eyes are a little off to begin with, then it's really throwing a whole degree of effort that your brain now needs

to exert £¨½ß¾¡È«Á¦£©," he said£®                    

         Dr John Hagan, a Kansas City ophthalmologist, said some people who do not have normal depth perception cannot see in 3D at all£®He said people with eye muscle problems, in which the eyes are not pointed at the same object, have trouble processing 3D images£®

         Rock Heineman, a spokesman for RealD, a provider of 3D equipment to theaters, said headaches and nausea were the main reasons 3D technology never took off£®

         Heineman said older 3D technology used two film projectors£¨·ÅÓ³»ú£©, one that projected a left-eye image and one that projected a right-eye image£®Three-D glasses would allow viewers to see a different image in each eye£®

         "People often complained of headaches and it was really because the projectors weren¡¯t lined up," Heineman said£®

         Now his company has developed a new single digital projector, which switches between the left and the right-eye image 144 times a second, to help overcome some of the old problems£®

         "By going to a single digital projector, those problems were solved," he said£®Friedman said he thinks most people will do fine with 3D movies and with 3D TVs, but Rosenberg said people may quickly tire of the novelty £¨ÐÂÏÊÊÂÎ£®"I suspect there will be a lot of people who say it's sort of neat, but it's not really comfortable," he said£®

1.The text is mainly about ____£®

         D£®those with eye muscle problems should not watch 3D movies

         A£®a single digital projector could solve all the problems with 3D technology

         B£®people will gradually become comfortable with 3D movies and TVs
