Sean, i can see this time you've opted for some ligther-tinted shades, are they photochromic perhaps? Anyhow, i am currently carrying out some extensive research on lens materials used by premium eyewear makers (Dita, Salt Optics, Akoni, just to name a few) - will definitely keep you posted on that, provided you are interested of course (i know you are more focused on performance-driven sunnies, but this "high-fashion" brands may surprise you, trust me!). Bye for now. Keep 'em coming ;-)
Hey buddy! These are the Costa Paunch with gradient tint. I wish they had a photochromic option! Love to learn more on what you find out. I have a lot to learn and our audience appreciate it too.
@@Engearment Well, for now i can tell you that all these premium brands seem to prefer the tried and tested cr39 for their sun lenses - granted, it's the cream of the crap for it's of optical grade and it's made in Japan - though still the most basic organic material there is. I've recently talked with a representative of the brand Akoni and he told me that their cr39 is as clear as glass, scoring a perfect 59 of Abbe value (the only other material with that high a score is of course crown glass) but i am still skeptical about this... Plus i've reads somewhere that the crystal lenses made exclusively for Oliver Peoples are some of the best glass lenses produced today. Those with the VFX polarized tech. Somehow, some high-end makers have opted for polyurethane for their sun lenses (Mykita uses a urethane material by lens manufacturer Tajima) and they too claim it's as clear as glass and as unbreakable as polycarbonate. They won't specify the lab tests that they carried out though... So, long story short: glass is still the king! With 'ole cr39 a close second. I'd steer clear of polycarbonate and nylon. Don't know about polyurethane... Thoughts?
Great review as always Sean. Always been a fan of OR gloves, have quite a few pairs, and these look awesome. Btw, what Patagonia jacket are you rocking? Something I bet we cannot get till next winter I bet 😉🤣
Love your energy in this video! You can tell when someone eally enjoys what they are doing. Greetings from Switzerland.

Agreed on the OR gloves being awesome. They know what they are doing.
Yep, next seasons Patagonia Snowdrifter jacket 😎😆
