When the first came out, the 3D Vision 2 glasses were the same price. They really aren't bigger, at least not compared to the wireless 3D Vision 1 glasses, but they are much more comfortable and lighter. I most definitely would recommend the 3D Vision 2 glasses. The glasses play no part in the lightboost process, that is on the monitor. They work the same, but for comfort value, the 3D Vision 2 glasses are much better.
