3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.
