While most of the warnings may be the work of overzealous lawyers, there’s “a small method to the madness,” says Dr. Norman Saffra, director of ophthalmology at Maimonides Medical Center.
迈摩尼得斯医疗中心的眼科主任诺曼·萨弗拉医生说，尽管大多数警告可能是过分热心的律师的“职责”，不过我们“多少还是可以理解他们对此问题为何如此疯狂”。
This is especially true if you happen to have an ocular condition – such as weak eye muscles, lazy eye or the inability to see 3D. In those cases, “you’re stressing the [eye] muscle system so that everything can stay in focus all the time,” Saffra says, “That’s why some people, after taking off the 3D glasses, have horrible headaches and can be disorientated, because things are off balance because their eye muscles have been strained watching the movie or TV show.”
如果你恰好有眼睛方面的疾病，比如眼部肌肉薄弱、弱视或看不了3D电视，这些警告尤其需要注意。有那些眼部问题的人在看3D 电视时，“你的眼部肌肉系统变得紧张，这样你才能始终集中精神，”萨弗拉说，“那就是为什么有些人在摘下3D 眼镜后，感到头剧痛，并失去方向感的原因——因为观看3D 电影或电视节目时会导致他们眼部肌肉痉挛，身体失去平衡。
