Three-dimensional anaglyphic glasses are used for viewing print, movies, Web sites, games and computer applications in 3-D, defined as two views of the same subject (either moving or still) in contrasting colors and slightly offset for two different perspectives. These IYF (In Your Face) 3-D anaglyphic glasses are re-formulated and supercharged with red and cyan filters, designed to punch full four-color 3-D with depth-defying clarity without compromising colors, flesh tones and light. "With the phenomenon of 3-D movies and with all the new movies planned to be released in the next two years, you need to be prepared for the rush. More and more children are having 3-D movie-watching parties. Most DVD rentals only come with two glasses and only four are packed in a DVD when you purchase them," Mark Nidzgorski, director of retail for American Paper Optics, told TDmonthly. Launch date: June 2009.
