3D TV Active Shutter Glasses

We are receiving many questions related to 3D TV active shutter glasses. Do I need them to watch 3D TV? How do they work and do I need to match the same brand as my TV? Where can I find the best prices on 3D glasses? We answer those questions and more below.

Lets start with the most popular question related to if you need 3D glasses to watch 3D TV. Right now, for TV, the answer is yes. There are technologies in the works that will not require glasses and you are likely to see this technology become available in none TV devices such as cell phones, computers and cameras fairly soon. However TVs will take a little longer due to some limitations. See 3D TV without glasses for additional details.

Now that we have established that glasses are needed to watch 3D TV lets look into exactly what is needed and how they work. There are three types of 3D glasses, however the TV manufactures have standardized on active shutter glasses so we will not discuss the other two types here. Unfortunately although manufactures have agreed on the use of active shutter glasses, they have yet to agree on how the glasses synchronize with the TV. This means that glasses will not necessarily work across brands of TVs and that you should purchase glasses of the same brand as your TV. Not that big a deal, but it does mean if your friends come over to watch a 3D movie or sports with you, they may not be able to bring, and use, their glasses if they have a different brand of glasses than your TV. So you will need to be able to supply enough glasses for everyone that will be watching 3D TV.

That last paragraph was pretty deep, so here are some details that will likely answer some of your follow up questions. First if you are interested in the learning more about how the active shutter glasses work and why they need to synchronize with your TV, see how the 3D TV works. Additionally if you are interested in more information about 3D glasses, such as where to find them at the best prices, or what the other types of glasses are besides 3D TV active shutter glasses, see 3D TV glasses.

A few more answers to some common questions. 3D active shutter glasses are designed to comfortably wear over your existing prescription glasses. Therefore if you currently wear contacts or glasses you will continue to do so and wear the 3D glasses over them.

The active shutter glasses are actually active, which means they need a power source and have batteries in them. Some are rechargeable and others require replacement batteries. Batteries typically last for about 70 hours of viewing before needing to be replaced or recharged. If you are curious about the need for batteries and what "active" really means, the how 3D TV works article mentioned above explains that also.
