Need help determining era/model for a pair of Julbo Glacier Glasses

I am pretty sure these are a pair of Julbo Dolomite Glacier Glasses, correct me if I'm wrong, trying to determine approx year they may be from or any additional information for my curiousity' sake. I think they're awesome glasses and would just like to know more about them.

I am by no means an expert on Julbos, but those look like the classic glacier goggle design which Julbo has had for decades. My buddy had them in the mid 70's.
