Small children should not watch films in 3D. It is because 3D films can make small children feel headachy , tired and nauseous . And how could 3D films impact their eyes in the long term ? It is still unknown . Our brain fuses two images together and we can see three-dimensional pictures. But for some young children, this process makes them tired and uncomfortable . It is because it puts a lot of strain on their visual systems. So do not just put small children in the lounge room . Parents should balance screen time with green time.

幼儿不该看三维电影
幼儿不该看三维（立体）电影。这是因为三维电影可能会使幼儿头疼、疲乏、恶心。从长期看，三维电影会对幼儿的眼睛造成怎样的影响呢？这一点还没有定论。我们的大脑把两种画面融合起来，这样我们就能看见立体画面了。但对幼儿来说，这个过程会让他们觉得疲乏，很不舒服。这是因为这个过程给他们的视觉系统带来了很多负担。所以不要只把幼儿放在客厅里。父母应该将幼儿看电视的时间与其看绿色植物的时间加以平衡。
