Nerf guns can cause serious eye injuries, warn doctors
Bullets from a popular children's toy can cause serious eye injures, doctors have warned.
London medics have reported that they have treated three people with internal bleeding around the eye, pain and blurred vision after they were shot with Nerf guns by children.
Writing in BMJ Case reports, the doctors recommended wearing protective eye goggles and said the safe age limit for the guns may need to be reviewed.
Hasbro warns players not to aim Nerf guns at the eyes or face.
On its packaging, it also advises that only bullets designed for the product should be used.
Nerf guns are designed for children aged eight and over and see youngsters blasting foam bullets at each other.
The company also sells replacement bullets or darts - but cheaper versions are also available online from other retailers.
The eye experts, from Accident & Emergency at Moorfields Eye Hospital, said the unlabelled bullet heads were harder and could potentially cause more damage - something that parents may not realise.
In their report, they describe the injuries of two adults and a child in separate incidents linked to Nerf guns.
One 32-year-old man was shot in the eye from eight metres away by a child with a Nerf gun. He suffered blurred vision and a red eye.
A 43-year-old woman was shot in her right eye from a distance of one metre and complained of blurred vision and a red, sore eye.
An 11-year-old child also suffered a shot in his right eye from a distance of two metres, and complained of pain and blurred vision.
He developed swelling of the outer layer of the eye (cornea), and the inner layer of the eye (retina), from the force and speed of the bullet fired by the gun.
All the patients were examined and treated with eye drops, the researchers said.
Check-ups after a few weeks showed that their sight had returned to normal.
While it was good news for the three patients, the doctors said that projectiles like Nerf gun bullets travelling at speed could cause long-term loss of vision.
One patient told the doctors that there were "numerous online videos which show children how to modify their guns to make them shoot harder, faster and further distance".
They added: "This case series emphasises the seriousness of eye injury from Nerf gun projectiles and calls into consideration the need for protective eyewear with their use."
But they said more research was needed to find out if eye injuries were on the rise as a result of toy guns.
The authors said they could not advise on a safe distance for shooting to avoid eye injuries on the basis of three patients.
