TV glasses have two main types. All of them are related to TV watching. Under most conditions, we mean the latter type when talking about TV glasses and TV sunglasses.
The first type is just normal glasses that will help when you watch TV and videos. They may reduce eye strain and improve vision effect. Special ones are 3D TV glasses. 3D TV glasses increase the depth of realism and create 3D images in front of you. These TV glasses look like ordinary glasses but with particular treatment on the lenses in order to achieve special TV effects.
The commonly said TV glasses and TV sunglasses are indeed complex devices. They consist of extremely thick lenses, cables connected to digital TV-out interface and earphone. You can watch TV and videos on them rather than on a real TV. TV glasses can create a virtual screen of as large as 50 inches from several feet away.
If you have a mobile phone that is capable of showing mobile TV, TV sunglasses do change the way we watch TV programs on cell phones. Mobintechs PDG replace the small screen of your handset and double the battery life, compared to watching mobile TV on the phone. Even if a call is in, you need not to stop your watching on the TV sunglasses.
TV glasses and TV sunglasses remove peoples concern that someone else may be seeing what they are watching. These devices can protect our privacy. Once you have portable TV tuner, 2.4G wireless AV or 3G mobile phone, TV glasses provide you with the most comfortable and convenient TV programs.
