Fiona North, Ophthalmic Adviser with the SHSSB added: Eye injuries caused by fireworks are extremely serious and can permanently damage eyesight. I would urge those who are co-ordinating efficient firework displays to use appropriate eye protection.
Fireworks blind people.
While fireworks are capable of causing eye injuries that are serious and may permanently damage eyesight, this does not necessarily mean blindness. It could be just visual impairment. Blindness was not mentioned. This was hard for the machine because it requires an illogical and counter-intuitive thought process to see this statement as anything but true.
