When my father’s eye was saved by his safety eyewear last week, everyone spoke about the advantages of wearing protective gear while in an industrial situation. Many of the workers were surprised that the projectile piece of plastic actually scratched and nicked the lens of the glasses. The safety manager of the factory said that the lenses must be a minimum of 1 mm thick to fit the requirements. It was verified the lenses were that thickness. The lenses did what they were supposed to do. They stopped the projectile from injuring his eye.
