The emergency room at the University of Iowa had never seen anything quite like the summer of 2017. In the months after Iowa legalized consumer fireworks, a steady stream of patients arrived with catastrophic eye injuries—some blind in one eye, others facing a lifetime of impaired vision from what was supposed to be a celebration. For years, advocates had successfully blocked legislation that would allow Iowans to purchase and use consumer fireworks. But when the ban finally lifted in 2017, the consequences were swift and severe. Researchers from the University of Iowa documented the consequences in a comparative study. The findings will be presented this week at the 129th annual meeting of the American Academy of Ophthalmology, the AAO said in a press release.
"Almost immediately, the emergency department began seeing a surge of devastating firework-related injuries," said lead researcher Ikenna Nwosu, BS MS, of the University of Iowa. "Patient stories of sudden, life-altering vision loss and the testimonials of physicians stretched to manage these cases made a lasting impression."
The study, which examined firework-related eye and orbital injuries before and after legalization, found not only a dramatic increase in cases but also a troubling shift in the age of victims. After 2017, patients arriving at the emergency department were younger on average than those injured in previous years.
"While we anticipated an increase after legalization, the scale was greater than anticipated," Nwosu said. The finding about younger patients was particularly concerning. "National trends already show higher rates of firework injuries in younger individuals, but it is especially harrowing to hear these stories firsthand and witness how these injuries can lead to lifelong disability."
The Iowa findings mirror a troubling national pattern. A previous University of Iowa study had already documented a rise in firework injuries statewide, echoing trends seen across the country. But the new research zeroes in on the specific toll on vision and the delicate structures around the eye.
The study's implications extend beyond Iowa. More than a dozen states have loosened restrictions on consumer fireworks in recent years, often under pressure from industry lobbying and arguments about personal freedom and economic benefits.
But researchers say the human cost is clear. "Fireworks are not harmless entertainment; they are explosives capable of inflicting life-changing harm on both users and those nearby," Nwosu said. "Protective eyewear, public safety education, and legislative awareness are critical to preventing these tragedies."
In response to the crisis, the research team partnered with Eye on July, a nonprofit organization, to distribute safety glasses at eye clinics and through community firework vendors. The goal, they said, is to reach consumers before injury occurs.
Nwosu hopes their findings will spark conversations among clinicians, policymakers and the public about prevention strategies. The toll on patients and providers alike, they say, has been profound—and entirely preventable.
