3D Cinema and Headache Relationship Analyzed
Scientists from Tartu university (Estonia) investigated a possible link between 3D movies and headache. This was a prospective, non-randomized, observational study. Six thousand specifically designed questionnaires were distributed to consecutive cinema visitors. Relative headacherisks for 2D- vs. 3D-movie visitors and the effects of background variables were analyzed.
For the first time, it was evidentially shown that 3D movies can provoke HA. Persons at risk are mostly younger women and/or migraineurs. Based on the study results, for those belonging to the aforementioned risk groups, it can be mainly recommended to choose passive 3D technology and to view movies from the farthest possible distance.
The study was supported by the Estonian Headache Society; the full pblication of the study results is available here.
