Calfing for Safe Celebrations
Last Fourth of July, Pete, a 14-year-old boy, was enjoying the lit-up skies and loud booms from the fireworks (烟花) being set off in his neighborhood. Suddenly, the evening took a terrible turn. A bottle rocket shot into his eye, immediately causing him terrible pain. His family rushed him to the emergency room for treatment. As a result of the injury, Pete developed glaucoma (青光眼) and cataracts (白内障). Today, Pete has permanent vision loss in his injured eye because of his bottle rocket injury.
June is Fireworks Eye Safety Awareness Month, and through its EyeSmart campaign, the American Academy of Ophthalmology (眼科学) wants to remind consumers to leave fireworks to professionals (专业人员). "There is nothing worse than a Fourth of July celebration ruined by someone being hit in the eye with a bottle rocket," said Dr John C. Hagan, clinical correspondent for the Academy and an ophthalmologist at Discover Vision Centers in Kansas City. "A safe celebration means letting trained professionals handle fireworks while you enjoy the show."
According to the U.S. Consumer Product Safety Commission, more than 9,000 fireworks-related injuries happen each year. Of these, nearly-half are head-related injuries, with nearly 30 percent of these injuries to the eye. One-fourth of fireworks eye injuries result in permanent vision loss or blindness. Children are the most common victims of firework abuse (伤害), with those fifteen years old or younger accounting for 50 percent of fireworks eye injuries in the United States. Dr Hagan estimates that his practice sees more than 30 injuries each year from fireworks.
Even fireworks that many people consider safe represent a threat to the eyes. For children under the age of five, apparently harmless sparklers (花炮) account for one-third of all fireworks injuries. Sparklers can bum at nearly 2,000 degrees Fahrenheit (华氏).
