Never worn sunglass frames from my fathers stock of eyeglasses when he was selling them to opticians and doctors from the 70's - 80's.
These 80's thin black metal aviator sunglasses are marked UV impact resistant glasses. The frames are a nice hard metal and the lenses are substantial. Not flimsy! the smokey gray lenses look great - not scratched or used!
Everyone needs some optical aviators! Originally made for men but looks mega-cool on either sex.
If this doesn't float your boat, I also have gold aviators and black plastic in my shop, http://forsythiahill.etsy.com.
