Help ID old glasses

Anyone have any idea what type/style of sunglasses Marcello Mastroianni wore in 8 1/2? Google has failed me on this one.

The answer eludes me but here’s a poster for the film.

The page is slow to load.

Hornrims?

That’s what I’d call them. The glasses on the right are similar to the ones in the poster.

Not his real glasses, the sunglasses.

Thanks though.

They’re kind of similar to these.

On the IMDB message board for that movie, someone suggested that they are Persol 2833S although the ones you linked to look very straight in front, and the Persol glasses have a slight angle to them.

They are called “Producer Glasses”

Here’s what they look like
