3D TV No Glasses
Look honey, 3D TV no glasses!!! Is this possible? If so how and what is required to make it work? Learn more below. Although it is currently possible to watch 3D content without 3D glasses, TVs do require glasses at this time.

3D programming is available to watch without glasses, however it is available on personal devices such as cell phones, hand held video games and computer monitors. The reason for this is that the technology does not provide a very wide viewing angle, meaning that you need to be sitting directly in front of it when watching to see the 3D effect. Obviously this will not work as well for televisions because multiple tend to watch at the same time and spread around the room.
There is technology in the works for television that will allow watching 3D without glasses, but at this time the TV manufactures have standardized on a 3D approach that requires Active Shutter Glasses. Active shutter glasses synchronize with the TV and actively manage what the eye sees by actually blocking one eye at a time as the TV shows the image for the each eye. To put it simply, to create the 3D image, the TV alternates showing two images slightly offset from one another. One image is for the right eye and one for the left. When the image for the right eye is shown the glasses block the left eye and when the image for the left eye is shown the glasses block the right eye. This all happens very quickly and is why the glasses are called active shutter, because the lenses are rapidly opening and shuttering in synchronization with the images being displayed by the TV.
In case you are wondering, active shutter differs from what most movie theaters use for 3D viewing. They originally used red cyan and now most are using a method know as polarization which requires polarized glasses.
3D TV No Glasses Summary
OK, to summarize the 3D TV no glasses article. You can watch 3D programming now without glasses, however not on TVs. There is technology in the works for TVs but it is likely a year away at best. TV manufactures have standardized on Active Shutter technology for the current 3D TVs. This technology is different from that used in movie theaters to watch 3D movies.
