It comes after three patients in three months attended Moorfields Eye Hospital in London after being shot in the eye with a Nerf gun from distances of 3ft to 26ft.
They treated three people with internal bleeding around the eye, pain and blurred vision after they were shot with the toy guns by children.
The report, issued via the Press Association, cited one 32-year-old man who was shot in the eye from eight metres away by a child with a Nerf gun. All the patients complained of blurred vision and red eyes and were treated to reduce pressure inside the eye, and their symptoms resolved after a few weeks.
The youngest patient, an 11-year-old boy, suffered swelling in the outer and inner layer of his right eye when he a Nerf bullet hit him from about six feet away.
Bleeding under the white part of the eye, the conjunctiva, is common and not that risky, Bizrah said, but bleeding in the space between the cornea, the eye's outer layer, and iris, the circular colored portion of the eye, is far more unsafe.
All the patients were examined and given eye drops, the researchers said.
Check-ups after a few weeks showed that their sight had returned to normal.
Though all three people made a full recovery, doctors are anxious the toys can cause long-term vision loss.
Julie Duffy, senior vice president for global communications for Nerf's maker, Hasbro Inc., wrote in an email that Nerf foam darts and foam rounds are not hazardous when used properly.
"The unlabelled brand by which the patient was injured was more firm". Instead, off-brand "ammunition" made by third party companies with no ties to Nerf itself often tends to be more risky, as different materials are often used in their production.
All the injuries documented in the case study involved Nerf guns shot from a close distance.
Commenting on the findings, Katrina Phillips, CEO, from the Child Accident Prevention Trust (CAPT) told HuffPost UK: "These sorts of guns are growing in popularity and new guns are being released all the time, so it's helpful for parents to know that doctors are seeing serious accidents with children's eyes".
The report also makes an interesting note that the soft foam projectiles made by Nerf aren't always to blame. Children should protect their eyes when playing with these guns, they advise. The guns should never be aimed at a person's eyes or face, and the products should never be modified, she said. "It would be great to see manufacturers providing eye protection, that's appealing to children, alongside the guns".
