i still see internet postings of guys firing muzzleloaders without eye protection and without hearing protection too. A good pair of safety glasses will protect ones eyes from any piece of primer that gets ejected from a muzzleloader under some worse case scenario.

Just came from another website where folks are having a cat fight about the requirement to wear safety glasses and hearing protection on certain firing ranges.

Yep, folks have a right not to wear safety glasses while shooting. They also have the right to complain after losing an eye.
