Guide to 3D Glasses

If you’re building a 3D home theater, you may be wondering, “Do I need 3D glasses to watch 3D movies?” and, if so, “What kind should I buy?” The answer to the first question is yes. You do need 3D glasses. But not the cheap paper kind of the past. Today’s technology offers two different types of 3D glasses to choose from: passive polarized or active shutter. We’ve put together this guide to 3D glasses to help you determine which type is right for you.

Passive vs Active 3D Glasses

What’s the difference between passive polarized and active shutter? Passive polarized 3D glasses are the more inexpensive option. They look and feel a lot like sunglasses and are similar to the plastic 3D glasses you’d get at the movie theater. Active shutter 3D glasses are battery-operated glasses that rapidly shutter open and closed. They have a transmitter that syncs the shutter rate with the onscreen display. Active glasses are a little bulkier and more expensive than passive glasses, but the technology is more advanced.

How to Choose the Right 3D Glasses

The right 3D glasses for your home theater will depend on what type of TV or video projector you have. Video projectors always require active shutter 3D glasses. TVs, on the other hand, vary among different brands and models. Some TVs require passive, while others require active. Refer to the user manual provided by the manufacturer to determine which type is right for your TV.
