Schematic illustration of experimental setup. Positive defocus was imposed monocularly in the right eye. The pupil of the left eye was tracked in infrared light (IR LEDs) with a custom-built eye tracker and custom-developed software to cover different parts of the movie frame in real-time with a gray patch while the subject watched a movie from a large TV screen at 2 m distance.
