Abstract
A possible link between 3D movies and headache (HA) has never been a target of specific and systematic investigations. The aim of this study was to investigate the relationship between 3D cinema and HA and to evaluate possible risk factors of developing HA during or after watching a 3D movie. This was a prospective, non-randomized, observational study. Six thousand specifically designed questionnaires were distributed to consecutive cinema visitors. Relative HA risks for 2D- vs. 3D-movie visitors and the effects of background variables were analyzed. The questionnaire was filled and returned by 1293 persons. The mean age of responders was 33.0 ± 11.3 years. Individuals who viewed 3D movies reported HA during or after the movie 1.61 times more often than 2D-movie viewers (11.1% in 3D vs. 7.2% in 2D movies, p = 0.017). The risk was higher in women: 2.65 times for 2D (p = 0.019) and 1.85 times for 3D movies (p = 0.06), and decreased with age by 4.6% with each year for 2D (p = 0.0035) and by 3.2% for 3D movies (p = 0.0098). Among 3D-movie visitors, those with previous HAs were 4.17 times more prone to get a cinema-induced HA (p = 0.02). The risk was the highest for persons with migraine (OR = 3.37, p = 0.001). 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 our 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.

Six thousand designed questionnaires were proportionally distributed to consecutive cinema visitors of three major cinemas in Estonia, located in three major cities – Tallinn, Tartu, and Narva – representation of major Estonian regions was ensured
Summary
Watching films in artificial 3D is a new experience for human brain. Anecdotal reports suggest a possible relationship between 3D movies and headache (HA). Possibility of a Despite these few reports, the question of a possible relationship between artificial 3D experience and HA has never been a target of specific and systematic investigations. A possible link between 3D movies and headache (HA) has never been a target of specific and systematic investigations. The aim of this study was to investigate the relationship between 3D cinema and HA and to evaluate possible risk factors of developing HA during or after watching a 3D movie
