To think otherwise would be similar to thinking that asking a quadriplegic to carry your groceries might somehow exacerbate his/her condition.
This is a different situation than a headache, induced by eyestrain in an adult. The adults eyes have fully developed muscles which will work really hard to do what the brain tells them to, even if it's something that is very difficult (trying to focus with a lens that no longer has the elasticity it needs to achieve it, etc.)
Eyestrain and headaches associated with 3D displays is real. I worked in the industry for 7 years, and it was one of those things every optical design had to take into account.
It would not surprise me in the least to find that headaches, or other adverse physical reactions to 3DTV, have something to do with pupillary distance. Every person has a pupillary distance, which is the physical distance between your pupils. Most are within a certain range, but it can vary widely, and a young persons eyes are closer together than an older persons are. When the source material is created, the producer has to decide on an arbitrary pupillary distance, which may be quite different from that of the viewer. I have seen it written that artificially expanding this distance augments (or exaggerates) the depth effect, so there's no real knowing how closely any particular media will coincide with any particular individual's own natural vision process, or the long term effects of prolonged viewing when it does not.
Video games which can be calibrated to create the different views based on the viewer are much better able to overcome this issue than static conditions during filming, so there is a distinct advantage on the gaming side...but probably only for one person at a time.
