Testing a 3D Blu-ray master for the home takes quite a few more steps than with a 2D master. Many qualitative factors are tested so that the content is true to the filmmakers intentions.
Blu-ray testers watch up to 12 hours of 3D per day and have built strong eye muscles. 3D is used by athletes to also build their vision systems and improve their stereopsis.
Over 100 3D movies were available in 3D Blu-ray at the end of 2011. Blu-ray discs are available through your favorite retail outlet.
