This lecture discusses the optical properties of 3D cinema glasses, focusing on the polarization angles of the lenses and how they interact when viewing other viewers' glasses. By analyzing the conditions for light transmission and opacity, the instructor explains the necessity of having the lenses polarized at 45 degrees to ensure proper separation of the left and right eye images. Different scenarios are explored, highlighting the importance of the lenses being perpendicular to each other and aligned with the Earth's surface normal for effective image discrimination. The lecture concludes by emphasizing the significance of maintaining a 90-degree angle between the lenses to ensure each eye sees the correct image in 3D cinema projection.
