Why do your glasses fog when go from the cold outside to a warm house?
When you are outside in the cold your glasses become cold. Because the air within buildings tends to be more humid than the air outdoors when the outdoor temperature is low, upon entering the house the water vapour in the air changes state from gas to liquid on the cold surface of your glasses. This results in your glasses fogging.

Active 3d glasses will not work with passive 3d TV. Active glasses use shutter 3D technology that requires a power source to power the lenses in the glasses. Passive glasses don't have electronics or batteries. Hence, they are lighter and more comfortable. Active and passive TV work using completely different technology and thus active glasses cannot work on passive TV.
