I mean if that's the definition of augmented reality - wouldn't literally all glasses be augmented reality since they either tint or do something to distort your vision?
Shoes, hats, many kinds of clothes are mechanical enhancements. Gloves for working without hurting one's hands, etc. All those things give a definite advantage over unprotected skin. I don't even start listing tools, which glasses are.
Less controversially, hearing aids and HDR goggles would also fit the bill.
