I don't know that there are sunglasses out there with polarized lenses but no UV protection (though I can't be sure).
Essilor and Luxxotica merged a while back. They're the same company.I got a pair last year from EyeBuyDirect. They're great. $73 because I now have to wear progressive lens. I could have otherwise gotten a pair for like $20ish.
I got the glasses in about a week and a half as I recall.
Their parent company is Essilor.
DeBeer?I work as an optician,its literally one the worlds bigger,if not the biggest cartel in the world,i struggle to think a company having such dominance in any field in such a vertical way,they bought/merged a couple years ago with Essilor which is a huge optic lens manufacturer company,wish they had a solid competitor.
