Bizarre: France government agency cautions children against watching 3D
Evidence free medicine: BBC News – French health watchdog warns on 3D usage for children.
- Scholar.google.com did not turn up any papers on the subject. Pubmed.gov did turn up some papers:
- http://www.ncbi.nlm.nih.gov/pubmed/23224123 – this paper formed an hypothesis, not a conclusion – and is referenced by the government agencies as the basis for this recommendation. The abstract says “As there is hardly any information available in the medical literature on this subject it is the aim of this article to provide an overview of the technology and physiology with the advantages and disadvantages.”
- http://www.ncbi.nlm.nih.gov/pubmed/23928879 – looked at a group of people with pre-existing vision problems to understand the impact of bad 3D imagery on them. Pretty much the same in this paper – http://www.ncbi.nlm.nih.gov/pubmed/24516978
Thus, these recommendations are based on the practice of evidence-free medicine.
