I use very good sunglasses, my dad has always insisted since i was little i wear good sunglasses. I used to sell sunglasses on the internet once and made alot of money out of it, I was only 15 in school, dont have time to do it anymore, and window cleaning pays so well
Raybans are the best imo. Getting a new pair of wayfarers soon. Bur for work a pair of wrap arounds is best, like Oakleys
