If your main concern in regarding a 3D is the safety of the eyes, especially for the kids, who will watch it for the long hours, you need to know about two technologies - active and passive viewing. Active or the shutter glasses lead to flickering or crosstalk while watching a 3D TV and start to hurt our eyes or even cause a headache. On the other hand, Passive glasses, which do not open and shut regularly have no flickering issues and allow many hours of television viewing without any problems. Active glasses come with TVs of companies like Sony and Samsung, while Passive glasses come with the LG Cinema 3D TV of the LM series. The latter are fickler free, as well as cheap. So if you decide to go for 3D TVs, do keep these points in your mind. And your kids will also enjoy playing games with the “Dual Play” feature; it is like playing opposite each other with the entire screen at your disposal!
