I dunno about scratch resistance or invincibility, but I do know that optics require very exacting tolerances.
I've heard people say that cheap glasses/optics will give them a head-ache.
There's also interesting things like polarized lenses.
Ever since my first pair of polarized lenses, I can't go back to non-polarized.
I've been wearing Oakleys for the years, because they are:
More scratch-resistant than cheaper pairs I have owned.
ANSI impact rated, more durable overall (frames can be bent, re-bent, and tweaked for comfort without fear of breakage).
Comfortable, do not come off my face.
When they do get scratched, worn and the frames get beat up, you can get a replacement pair from the manufacturer for 50% off. Which is still expensive, but for polarized glass lenses, it's a nice bonus.
