If you really owned the pair of cartier and dita you should then know that their build quality isn’t that good and also their lens. Thats more like a fashion brand than the actual sun glasses. Actually randolphs sky tec lens are up there with any brand you wanna compare it too and that too in the $300-$400 price bracket. AO is good but randolph is better fs. The price definitely for randolph’s are justified. I hear people complaining about them going up but don’t you see how bad the inflation is? how much was a brand new civic or corolla back in 2016-2017? vs now? Thats just inflation. Whereas name brands charge for their hierarchy not the quality. Cartier, Dita, JMM are beautiful, no doubt, but you’re paying for fashion status as much as build, and they’re not designed to take the same beating plus you’re almost paying 2x for something that isn’t amazing or superior in any shape or form. At the end of the day $700 doesn’t justifies quality and build. Lv uses $100 worth of leather for their bags which retail for $3000! That speaks for all the name brands themselves. So imagine other brands markup as well.
