"What We Tested: Seven pairs of 3-D glasses \u2014 three that came wrapped in plastic, and four that didn&amp;#039;t (but were supposed to have been cleaned by theaters between uses). At theaters where we weren&amp;#039;t able to take the glasses home, we swabbed them and sent the swabs for testing to EMSL Analytical, an independent lab in Cinnaminson, NJ, along with the other glasses.  What We Found: None of the glasses were sterile. While most of the bacteria we found weren&amp;#039;t reason for alarm, one unwrapped pair was contaminated with Staphylococcus aureus, which can cause skin infections, conjunctivitis (pinkeye), food poisoning, and even sepsis or pneumonia.  Protect Yourself: According to our lab findings, the most effective way to clean 3-D glasses was with an alcohol wipe from the drugstore, which reduced bacteria more than 95 percent in our tests. A soap-and-water wash in the restroom sink was almost as effective. Don&amp;#039;t just rub glasses with a dry tissue, though \u2014 that wiped away only 66 percent of germs.
