但芝加哥西北大学费恩柏格医学院的眼科学教授迈克尔•罗森堡博士说,长时间观看3d电影可能会导致头痛。

dr deborah friedman, a professor of ophthalmology and neurology at the university of rochester medical center in new york, said: "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. this disparity for some people will give them a headache."
