At the bottom of the page they say 3D images (not just 3DS) could have adverse effects on kids 6 and under, so they should play in 2D mode, and it's possible for the system to be locked in 2D mode in the parental controls.
They don't specify why it might hurt their eyes, though. Maybe it's just to be on the super safe side.
I think they're just playing safe, I read that there isn't a study that indicates 3D vision can be harmful to kids eyes but that since kids are still developing his eyes they shouldn't see 3D images or something like that.
