ABSTRACT

Historically, 3D movies have been associated with audience eyestrain and headaches due to technical issues and poor planning. The real problem was not eyestrain; it was brain strain. A viewer’s eyes can only send images to the brain with a note attached: “Here are two pictures, figure it out.” If the brain can’t “figure it out” it will unnaturally realign the eyes or become confused by the two conflicting images sent from the eyes. Eventually, the brain goes into strain mode and the audience gets headaches, eyestrain, and occasionally nausea.
