Safe Celebrations This Fourth of July{{/B}}
? ?Last Fourth of July,
Pete, a 14-year-old boy, was enjoying the lit-up skies and loud booms from the
fireworks 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 and cataracts. 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 wants to
remind consumers to leave fireworks to professionals. "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, 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 account
for one-third of all fireworks injuries. Sparklers can burn at nearly 2,000
degrees Fahrenheit. |
The American Academy of Ophthalmology calls on consumers to
A:celebrate the Fourth of July with fireworks. B:leave fireworks to professionals in their celebrations. C:stop celebrating the Fourth of July altogether. D:set off fireworks together with trained professionals.
