I've been trying to find similar glasses and I found these.

I got the Gold | Brown Gradient they look almost identical but the lens Gustavo has are more transparent. The brown gradient lens are a little to dark.

The Gun Frame/Gradient Green-brown Lens are more similar to the lens Gustavo has but the glasses don't look the same. I ordered a pair to see how they look in person. Ill update my thoughts on these when they arrive

I hope this is helpful to anyone still searching for a pair.
