Vintage Bausch & Lomb Ray Bans, Help ID and date.

Good morning all,
I took this pair of ray bans in trade and now I am trying to find out about them. i can find similar pairs that sellers are stating 1970's.
I know that bausch & Lomb sold Ray ban in 1999 so they are at least older than that. They came out with the Olympian in 1969.
But if you combine the style, wire frame and the Olympic logo there seems to be none. Any help appreciated.
On the gold bar above the nose on the top it reads B & L ray Ban USA. the bottom of the bar reads B & L Ray Ban 61 O 15
Both Lens's have the BL logo and one has the olympic logo under Ray Ban.

Looks like it could be a 1992 "reproduction".................. https://www.google.com/search?client=firefox-b-1-d&q=B+&+L+Ray+Ban+61+O+15

 

Thanks for the help. @Hollyblue Which one showed them as reproduction?

 

The top 2 I think,reproduction could be the wrong word used,more like a reissue of an older style for the 1992 Olympics in Barcelona. I remembered what the numbers are,61 is the lens size and 15 is the bridge size with a square between them.

 

yes 61 and 15 with the square, but my keyboard doesn't have a square lol. Ill look at them again.
