Treatments for eye conditions that cause 3D vision viewing include surgery for cataracts or glasses/contacts to correct poor vision in one eye. What: Arch Oboler’s Bwana Devil in spectacular Natural Vision 3D When: Tuesday, July 14, 1953, commencing sometime around sunset at 9:03 PM under a Waxing Crescent Moon Where: River-View Drive-In, Mary Ingles Highway (Route 8) in Dayton, Kentuckyon the banks of the Ohio River, across from Cincinnati How: Two interlocked projectors with boosted light output and polarized filters, a screen. Other conditions that cause 3D movies to fall flat include lazy eye (amblyopia), strabismus, keratoconus, or poor vision in one eye due to cataracts, glaucoma or retinal problems. The condition is called vergence accommodation conflict. About 2 to 3 percent of people have an eye condition where only one of the eyes turns inward to track a close object. When seeing a 3D movie here in the States, it is best to carry an antibacterial spray or wipe - just in case.ģD can have some advantages - some patients actually discover health problems because they are unable to see the images clearly. They confiscated 7000 pairs of 3D glasses from cinemas, stating that they were not properly disinfected between screenings and lacked tags that proved that they do not cause vision problems. In Italy, the ministry of health has other concerns about 3D movies - specifically the cleanliness of the borrowed glasses. Today's 3D with digital technology gives crisper, clearer images and fewer problems, however there is still a risk of visual fatigue and "simulator sickness", a type of nausea that also plagues users of flight simulators, head-mounted virtual reality displays and other 3D applications. Produced and directed by Arch Oboler, the picture has an African locale and stars Robert Stack, Barbara Britton and Nigel Bruce. These tended to give viewers headaches, eyestrain, and nausea. Bwana Devil, the first feature-length 3-dimensional color film in history, went before Natural Vision’s 3-D cameras on June 18. This creates the illusion of three dimensions.Įarly 3D movies used color to set the images apart, and viewers wore paper glasses with one lens colored red and the other colored blue. The two images travel to the visual cortex, the area of the brain primarily responsible for processing vision. Special polarized glasses are worn that force one of the images to enter the left eye and the other to enter the right. To generate a three-dimensional effect, a special projector displays two identical images on the screen, but from slightly different angles making one appear close and the other to appear far away. ESPN has launched a 3D channel, which broadcast 18 of the World Cup soccer matches, and Discovery plans their own channel in early 2011. There are approximately 20 3D movies set to release in 2010. ![]() ![]() According to the National Association of Theatre Owners, almost 10% of US movie screens are now capable of projecting in 3D, up from 1.5% in 2007. Stephen Glasser, a Washington optometrist, says that more people may discover eye problems as 3D movies become more mainstream. However, one issue hasn't changed over the years - eye-related health issues can be a problem. The technology for 3D movies has come a long way since the first American color feature Bwana Devil in 1952. ![]()
