Please help identify these logos on vintage glasses

Hi
I have a pair of vintage glasses with an inverted v logo on the side with a dot each side of this
The frames are gold plate and the lens virtually frameless except for a vine leaf holding the glass which is bevelled. Can anyone help identify that logo.

On my second pair the other logo is enamel into gold plate on the side of the glasses, I am lost even to wether its a logo or just part of the design , can anyone help please.
Thankyou in advance for any help you can offer, after hours of research I am still no nearer

 

I think the purple glasses logo is a W (Very cool shape lenses!)

 

Hi Melanie. Yes! I see where you are coming from with that. The frames are incredible quality. They have to be a good designer just who?

 

If it helps, they appear to be 1980s.
