With one red lens and one blue lens, these glasses work the same way as the glasses used in the 1950s for viewing 3-D movies. Today they are most popular for viewing anaglyphs (two-color, 3-D still images), such as those sent back by the Mars Exploration Rovers Spirit & Opportunity. Sold in packs of five.
