The initiative stems from the fact that more than 900,000 Catalan and more than five million people in Spain can not watch movies in 3D, ie that 12% of the population is unable to appreciate the three dimensional visual effect, showing deficits in processing such images, very common recently with the appearance of films in cinemas and on television screens and games consoles.

The American Optometric Association estimates that up to 56% of people between 18 and 38 years could have problems with binocular visual health.

The COOOC wanted to emphasize that technology itself is not harmful, but the problem must be found in a defect of binocular vision, joint and coordinated vision in both eyes. Thus, the images for each eye reach the brain, combining leading to a unique three-dimensional image.

It is sufficient that one of the two eyes do not work properly or that both lose their coordination to prevent this fusion of monocular images that disappear in 3D or stereoscopic vision. Although you might think that this technology is harmful to vision, COOOC states otherwise, since it requires to exercise the skills fusional for those with unconsolidated binocular vision.

To symptoms such as dizziness, fatigue, double vision is necessary to visit the optician optometrist to get a full visual inspection.

The president of COOOC, Alfons Bielsa, explains that "a slight dizziness is normal, but if it persists, is a likely sign of presence of visual impairment." In the case of children, Alfons Bielsa stressed that "put a blank face to the spectacular 3D film effects, we can almost be certain that we are facing a binocular impairment."

The problem usually has a solution in most cases, being treated with vision therapy and / or prismatic lenses, accompanied by postural and ergonomic recommendations. In parallel, Fabio Delgado, a member of the COOOC, explained that this type of vision is also essential in creating spaces and distances, and therefore driving.

COOOC campaign, presented this morning in Barcelona Comedy Cinemas will begin in July at various cinemas Catalan self-diagnostic tests that will take place in October in schools. Elisenda Ibanez, COOOC Communication, has expressed his desire to "reach the largest number of cinemas and schools as possible to detect the maximum of cases"
