A little small talk with patients about 3-D games and movies might reveal subtle eye disorders. Although there’s no evidence of permanent damage from watching 3-D movies or playing 3-D videogames, the increasingly popular movie/game format may help sniff out eye disorders.
According to a study from the College of Optometrists, 3-D movies can act as a litmus test for people who have underlying vision problems. Some people who aren’t aware they have any vision problems find 3-D movies uncomfortable to watch, or impossible altogether. Their eyes aren’t able to perceive the depth that 3-D movies require, which can indicate more serious vision deficiencies that may otherwise go undetected. Because many underlying disorders don’t affect daily activities, 3-D movies act as the catalyst.
“Although people have reported experiencing symptoms when watching 3-D content, specifically headaches and eyestrain, there have been no studies whatsoever which have detected any permanent damage,” said Dr. Peter Howarth of Loughborough University. “Furthermore, stationary examples of these types of pictures have been around since Victorian times (Wheatstone stereoscopes), and films have been around since the craze for them in the middle of the last century.”
