Sunglasses - dating and identification help

[plousia]

Hi all, hope I'm not wearing out my welcome on this forum. I have tipped in the past and promise to do so again!

I bought these sunglasses thinking they might be vintage but now I'm not so sure. After getting them home I found a faint CE marking on one earpiece, which means they must be 1993 or newer (of course they could still be vintage, but I have no idea of the dating).

I also cannot figure out who the maker might be. They have a mark which reads "SG" on the inside of the nose bridge thingies (what are those called?) Googling "sunglasses SG" doesn't come up with anything useful.

Any help re: dating and/or maker much appreciated!

After doing some more research, I think these are probably from the 90s. See for example https://www.insider.com/sunglasses-...op-stars-lightened-up-with-colorful-lenses-16, especially the photo, and this article about the history of sunglasses which states " the 1990s trend was smaller with colorful tints."

Still no clue about the maker though, so if anyone has any ideas they are welcome.
