In the recent past there have been a number of amazing innovations in the world of 3D entertainment, from movie theater technology to what we see at home, to highly developed games. As time goes by and the technology becomes more and more affordable, it seems likely that viewing images with 3D glasses could become a part of day-to-day life for many. Now researchers say that might not be a good thing, as the dangers of 3D glasses come to light in research.
3D glasses can reportedly be very unhygienic(不衛(wèi)生的). Health officials in Italy recently confiscated (沒收) 3D glasses that they claimed posed health risks because the 3D glasses weren’t cleaned properly between screenings. The other more obvious dangers of 3D glasses remain. Researchers at the University of California, Berkeley have found that viewing 3D movies with 3D glasses can strain the eyes by changing the relationship between the eyes and the brain. This can result in headaches and blurred vision, and it seems that the problem is particularly troubling for young children. Those who do experience these kinds of painful side effects should limit their 3D viewing, as long-term results haven’t been found.
What should be done about the dangers of 3D? Well, the headaches and dizziness that some viewers experience can be reduced simply by lessening the amount of time spent using 3D technology and those who experience the effects for a long period of time should consult their doctors.
