I bought a pair of these AO Pilot aviators and love the distortion-free view through light gray lenses.

The frames and lenses are not particularly prone to damage, as I often carry them loose in my pocket.

I'm partial to the shiny chrome finish, which is a separate choice from matte chrome.  Fit is wonderful, and comfortable as they hug the head, and not annoying.  I wear unsized hats in medium and have an average hat size (7 1/4) with oval face, and 55mm was the right size for me.  How far spaced apart the lenses compared to more modern frames gives them a vintage Korean War-era look.

An economical imitation of these aviators, more squared off, and clearly  not as well made, is available for $10.00 from Pugs, a gas station brand.  I bought the Pugs first, and once I tried these AO aviators after that, I could see where the extra $30.00-plus went. Both shades are priced fairly.
