IMAX is not superior technology. It uses a linear form of polarization that can easily cause headaches or disorientation with a slight turn or tilting of the head. The newer techonologies such as RealD and Dolby 3D use a circular polarization and dichroic filters to present the two different images respectively. This will not completely eliminate headaches and discomfort for all viewers, but tends to cut down on the side effects considerably. It is likely that if you had some problems with 3D initially over time this would subside with more frequent exposure. Similar is one who is on a boat and develops sea sickness. If you stay on the boat or are exposed to boats more frequently you tend to develop your "sea legs." Also, kids should not view 3D content for more than a couple hours a day and maybe only a couple hours a week. The binocular system (how the eyes work together) is still developing up to about 12 and possibly longer. This could effect their ability to see depth in the future if they are constantly tricking their eyes into seeing depth for multiple hours a day.
