I used to work in the Emergency room in Detroit. One day they brought in a 14 year old kid who was shooting his BB gun in the basement of his home without eye protection. He hit something hard and the BB traveled back down the line of sight and pierced his eyeball. I saw the X-ray...one little BB floating in the center of the eyeball. They removed his eye.....think what an inexpensive pair of shooting glasses could have saved.
