There are certain shooting certifications the eyewear makers have to pass to be "shatter proof" whatever that is....I like the term "impact resistance"...I'm sure they make Oakley's designed for the shooting sports.
As for the expense...well only you can decide what your eye sight is worth. Side impact is also a factor...ever been shooting next to someone when their gun "let go"...Oh yeah....pass the tissue please..
