How Do 3D Glasses Work?
In the past couple of years, 3D technology has become more and more popular, with 3D films such as Avatar, Saw 3D, and Legends of the Flight doing well at the box office. Moviegoers can view the three-dimensional images by wearing 3D glasses when watching movies. However, those that already wear glasses to correct myopic, hyperopic, and astigmatic vision may find it difficult to wear their 3D glasses over their regular glasses. These men and women could benefit from LASIK or PRK surgery, procedures that can help patients get 20/20 vision without relying on visual aids such as glasses or contact lenses. People with perfect vision have no problem wearing 3D glasses, so they can enjoy three-dimensional movie technology with ease and comfort.
