3D glasses are what turns a 3D-capable display or projector into an actual 3D image for the viewer: active shutter glasses synced to the display's refresh rate, and passive polarized glasses paired with displays built for that format. Without the matching glasses, a 3D-capable screen shows nothing but a flat, doubled picture.
Glasses must match the display's 3D technology exactly - active and passive systems are not interchangeable, and active glasses are often further paired to a specific display brand's sync signal. For classrooms, theaters, and multi-seat viewing, passive glasses are typically the more practical and lower-cost choice per seat, while active glasses suit smaller, single-system setups. Battery life and comfort for extended wear matter for active models used in longer programs. COLAMCO supplies 3D glasses matched to the displays and projectors business, government, and education programs already run.
