There you go, another warning about playing with toy guns that fire projectiles. Doctors are warning Nerf gun users better take precautions in protecting their eyes when playing which looks like a tame game. Doctors from Moorfields Eye Hospital in London are calling for the use of eye protection. In the BMJ Case reports, the doctors treated three people from unrelated incidents in which they suffered internal bleeding around the eye, blurred vision, and pain when they were shot at by children.

They also recommend that the age limit for the safe use of Nerf guns by children should be reviewed.

Nerf is owned by Hasbro, which is one of the biggest names in toys. According Webmd,  spokesman from the company said, "Product safety is of utmost concern at Hasbro. Nerf products are designed based on years of consumer insights and research and undergo rigorous reviews and testing to assure that they are safe and fun to play with and meet or exceed global standards and regulations.

"Nerf foam darts and foam rounds are not hazardous when used properly. Consumers must never aim Nerf blasters at a person's eyes or face, should only use the foam darts and foam rounds designed for specific Nerf blasters and never modify darts or blasters."

Whilst the company also produces the Nerf darts, players can also buy cheaper and unauthorized version from other vendors online and they are usually not the same as the Hasbro specs. The doctors say they can be harder and can cause more damage. They also mentioned that a patient told them there are videos on how to modify Nerf guns to shoot faster, harder, and at a longer range.

There is always one thing that we should always remember: if we play or work with anything that has projectiles, or can produce parts that can just blow up, wear eye protection. Even if Nerf darts look harmless, we’d rather recommend wearing eye protection. Just like in airsoft, Hasbro recommends not to aim at the eye or head so not to accidentally hit the eye. But do not take chances as accidents happen.

Whether you buy Nerf for office warfare or for playing with the kids in background, it’s best to bring eye protection. Basic eye protection is very much affordable and it will save the money to go to the doctor.
