Pregnant women, drunk people and “those who are sleep deprived” should not watch 3-D television because of potential health issues, electronics manufacturer Samsung says on its Web site.
The company also says people at risk for stroke or epileptic seizures should consult a medical professional before watching TV in three dimensions.
Samsung and Panasonic began selling the first 3-D TVs in the U.S. last month.
The warnings come as other TV manufacturers are set to debut 3-D home entertainment systems this year. When watching 3-D TV, users wear special glasses with lenses that open and close rapidly to produce an image that appears to leap off of the screen.
