Review confirmed by purchase 
Lightweight but seem solid. I am very positively surprised by the Platinum coating! I immediately ordered another model, this time with polarization. Most of my glasses, due to long exposure to full sunlight, would crack right in the middle of the nose. Here, the nose piece is made of polycarbonate, which gives hope for long-term use. It's a real pity that there isn't a version with black temples, because I would blindly order another pair.
