Doesn't make any difference to 3D's adoption in my cynical opinion. The Stewart report on mobile phones underlined a known and not understood neurological stimulation from mobile signals, particularly the digital pulsing, a different effect to the concerns of localised heating caused by microwaves. The recommendation was to keep developing brains away from mobiles, and yet no-one paid any attention.I read an interesting article the other day that went beyond "lazy eye" and was directed at the concern of young children's ability to spatially differentiate depth and that 3D may pose issues with the brain's processing of depth in addition to concerns related to the article.
The future will be people bumping into lamposts because they aren't spacially aware!
