You will need one set of 3D glasses for each person watching 3D TV. You can watch 2D programming without the need for glasses.
When you purchase a 3D TV, you should pay close attention to the description. Some 3D televisions will come with one or two sets of 3D glasses while others will require you to purchase your own glasses. You can also purchase smaller glasses designed to fit better for kids.
In the end, pay close attention to how many pairs of 3D glasses your TV comes with and be prepared to buy a set or two more for the family. And don’t forget that you’ll certainly want to show your new 3D TV off to friends so having an extra set or two for movie night won’t hurt either.
