Ejecting cartridge casings can indeed pose a significant risk of eye injury while using firearms. When a firearm is discharged, the action of the gun forces cartridge casings out, sometimes at high speed and with considerable force. If these casings make contact with a person's face or eyes, they can cause injury, ranging from minor irritation to serious damage. This is why eye protection is a crucial part of firearm safety practices, particularly in shooting sports and at ranges, where this kind of risk is prevalent.

Targets generally do not pose a direct risk of eye injury during the shooting process unless they are made of materials that could splinter or shatter upon impact. Shooting range rules are designed to promote safety and do not inherently pose a risk, while hearing protection is essential for guarding against noise-induced hearing loss and does not create a risk of injury to the eyes. Thus, the danger associated with ejecting cartridge casings makes it the correct answer in relation to potential risks of eye injuries while using firearms.
