As we get closer and closer to being run over by a wave of 3D televisions, Blu-ray players, and assorted peripherals, we can start to see more of the details of that oncoming rush. Most recently revealed is the battery life of Sony’s active shutter glasses. As we’ve reported before, Sony is diving face-first into 3D technology for the home and each face that wants to follow along will need a pair of $133 TDG-BR100 or TDG-BR50 glasses perched upon it. Both models will manage 100 hours of active viewing before running dry — less than half the 250 hours Panasonic is pledging for its peepers, but more than double the 40 hours for NVIDIA’s option. 100 hours sounds like a lot, sure, but coming hot on the heels of Nielsen’s 35 hours per week of television report, we’re thinking you’d better keep that recharger nearby.
