3D content 'delivers 3D images with different left and right images, [which] has a potential impact on the growth of children's eyes.'
This is not only false, but illogical as well. The whole purpose of having two eyes at different locations is to see two different images at once and see 3D. Showing the eyes two different images is exactly what should be happening. The problem is actually with the fact that a 3D video will have arbitrarily-selected and static areas of focus, while human eyes typically handle the focusing on their own. Because of this, uninformed people will watch the movie and accidentally (and usually repeatedly) try to change their focus and strain their eyes because the image does not change focus at all. If people would understand this and focus solely on what the video is focusing on, they typically wouldn't get headaches, provided the shuttering/refresh rate is also suitable.
I recently decided to explain this to my friends, and all of a sudden two of my friends who always had headaches after 15 minutes were able to watch a full movie, with off-the-shelf consumer 3D technology nonetheless. Go ahead; try it - just make a conscious effort to not focus on anything except what the video is focused on and watch the eye strain nearly disappear.
Uh. Even a really strong magnet isn't going to provide much resistance.
