The Ogden Standard-Examiner quoted Phil Lelyveld of the USC School of Cinematic Arts’ Entertainment Technology Center about 3-D movies. “The two-color glasses, used for years and years, go back to the 1800s. They achieve the 3-D effect by sacrificing color,” Lelyveld said. “[The newer] polarized glasses are slightly gray in tint, and they don’t take the color out. With polarized glasses, which look like sunglasses, the light is spinning clockwise in one eye and counterclockwise in the other.”
